Garmin 920XT – GLONASS vs GPS which is best and what is GLONASS anyway?


Original Source

Original Source

GLONASS is Russia’s version of GPS. It tells electronic devices where you are.

It is increasingly used in high-end SMART devices, including the new Garmin 920XT.

GLONASS is neither particularly better nor worse than GPS.

HOWEVER, when they are used TOGETHER accuracy *IS* increased.

It is often said that using GPS+GLONASS can gie accuracy down to 2m and can also improve accuracy in buil-up areas; especially in the Northern Hemishpere (that’s where Russia is, right?).

Downsides: None really. Might use a tad more battery power though.

Do I really need it? Maybe the orienteer or golfer might benefit from super accuracy but I don’t think many people will really NEED accuracy to 2m. It should make running pace more accurate but you don’t NEED it to become an awesome runner, cyclist or triathlete/duathlete.

Garmin ® Announces Gear Tracking and Group Posts for Garmin Connect ™



GEAR TRACKING: This is a nice new feature in Garmin Connect for some.

Useful to let you know when you need to replace your trainers or a tyre maybe

There is a similar feature in SportTracks and I confess to not having the time to ever really use that. Still, we are all different – this will be music to someone’s ears no doubt.

GROUP POSTS: This could be an interesting feature to help athletics/tri club members communicate and share results/workouts/plans…not looked into the details myself yet.

—————- PRESS RELEASE FOLLOWS verbatim ——————-

We’re excited to announce additional features for Garmin Connect including gear tracking and group posts. These features are available for users now in the modern view of Garmin Connect.


Gear Tracking – Users can now track the distance logged on multiple types of gear, including running shoes and cycling equipment, in Garmin Connect. Simply assign gear to an activity to keep track of wear and tear.


Group Posts – Users can communicate with members of a Garmin Connect group by posting, commenting or liking a post. Group admins can also post an announcement that displays at the top of the activity feed, and members can now set notifications to receive an alert that another member has posted a comment to the page.


5k: Straightforward Improvement Plan

For a more detailed look at running relatively fast 5km races then have a look at this post:

However that post is NOT for everyone. If you are a 25 minute 5ker or slower then you might want to look at and consider the following straightforward plan to get going. It assumes you have a GPS watch that displays your running PACE.

IMG_3202Start on number 1 each week:

1. A long run

  • If you can’t yet run 1 hour non-stop then that should be your first goal. If you can run 30 minutes non-stop then just keep upping the distance/time slightly each session. If you are absolutely exhausted, panting and sweating then you are going too fast. Slow down to a comfortable speed.
  • When you next do 35 minutes then perhaps the time after aim to do 2x lots of 20 minutes with, say a 5 minute, break in between. These ‘intervals’ let you do a harder session without your body feeling it quite so much.
  • You might want to have a day or 2 off before you try again
  • Once you’ve achieved the hour then you can start to add in other distances and speeds. But keep the weekly long run of 60 minutes going, maybe perhaps trying to do it a bit faster as the weeks go by. But aim for a constant manageable speed if you can.
  • Increase the distance/time to 90 minutes. That’s probably further than you need so don’t specifically target going further than that.

2. A long yet a bit faster run

So you can run for an hour right? OK, let’s continue. But make sure you had a rest yesterday.

We’re going to try 3x 10 minutes at a bit slower than your race pace but a bit FASTER than your long run pace. In fact we’ll aim for 30 seconds per km slower. So if you can do 5k in 30 minutes that’s a pace of 6:00/km so you will run at 6:00 + 0:30 = 6:30/km. That’s a good pace you can try to make it a little faster if you want but I would rather you aim, instead, to maintain that pace for longer so we’re going to start with 3×10 minutes at that speed but if that’s too easy then go for 2×15 minutes (in subsequent weeks) or 3×15 minutes or 2x20minutes.

Do that once a week.

Over time aim to bring that speed down to FASTER than your race pace. This SHOULD be relatively straightforward to do. In the above example you would ultimately be aiming for, say, 5:45/km pace.

3. Miles

Run 3x 1mile at fast than your race pace, resting for 4-5 minutes after each mile. You might be looking at something like 5:30/km pace in the above example.

4. Speed

Occasionally do 30 second or 1 minute intervals at a very fast pace. Resting a minute or so in between. Aim to do about 8 minutes worth of effort. Do this once every couple of weeks, especially as your race draws near. (Then do some research on ‘tapers‘)





Reblogged from an original By Coach Mike Arenberg

In the last issue, I wrote about three New Year’s Resolutions to make triathletes fitter and faster in 2008. For the run resolution it was simple: do more tempo runs. Many elite and international coaches will tell you that one big reason that the East Africans are so dominant in distance running is that they do a huge amount of tempo work.

Coach Joe I. Vigil, Ph.D., coach of Athens Olympic marathon medalist Deena Kastor and Meb Keflezighi wrote, “Volume runs, when combined with a regular diet of tempo runs, are the single most important workout for the development of the distance component.” Dr. Jack Daniels adds, “Tempo running is one of the most productive types of training that distance runners can do. Training at this pace helps runners avoid overtraining and yields more satisfying workouts and better consistency.”

The purpose of tempo runs is to stress lactate clearance, not to overstress it. Done properly, tempo runs will increase anaerobic threshold, the point at which lactic acid starts to accumulate in your muscles. Not so long ago, Vo2max was the physiological measure considered the best indicator of running potential. Vo2max is the maximum amount of oxygen that your body can process to produce energy. The ability to run at the highest possible percentage of a runner’s Vo2 for a longer time is the result of one thing–tempo work, and lots of it–over a long time.

All the speed work, weekly mileage and Vo2max workouts won’t mean as much as they will with the addition of regular, consistent tempo work. If you read about the Kenyans’ training, it revolves around tempo work. Recently, Vo2max has lost its standing as the best predictor of running performance. A new measure, vVo2, has come to the forefront as the best indicator of running performance. vVo2 stands for velocity at Vo2max, or how fast you’re running when you reach Vo2max. Thus, it factors in your running economy, in addition to your cardiovascular and muscular capacity.

How Does It Work?

Most runners have trained their bodies with lots of long, slow distance running to deliver oxygen, but they haven’t trained their bodies to use it. Tempo running does just that. During tempo runs, lactate and hydrogen ions are released into the muscle. The hydrogen ions make the muscle more acidic. The better trained you become, the higher you push the threshold at which this occurs. This means that your muscles become more efficient at dealing with these byproducts. The end result is a less acidic muscle, one that has a new, higher threshold.

What Is Tempo Work and How Do I Determine Tempo Pace?

Tempo pace is not a single pace, but rather a range of paces both faster and slower than a calculated target. There are anaerobic threshold runs and aerobic threshold runs, both very effective. In our summer running program we use both, each done once per week. Tempo runs can be single bouts, such as 20-50 minutes at a specified tempo, or they can be run in two or more segments or bouts. (Some marathon runners do tempo runs in excess of 60 minutes). For instance, 20 minutes of tempo running can be divided into two segments of 10 minutes at tempo pace with 1-2 minutes easy jogging between segments.

The most important thing is to have an accurate idea of what your tempo pace range should be. Determining this is easier than you think. First, you find your vVo2, and then you do a little math.

There are many ways to determine vVo2, but the simplest method is to run a 1-mile time trial. Your pace for this effort is your vVo2. Then do the math. Your threshold training pace is 85-87% of your speed for the mile, and your aerobic threshold pace is 75-80%. It’s important to note when calculating these ranges that it represents a percent of velocity, not percent of your mile time. For example, if you run the mile in 6:30, your threshold pace would be 6.5 minutes divided by 0.85-0.87, or 7:28-7:39 pace. Your aerobic threshold pace would be 8:07-8:40 pace.

Another method is to run a 6-minute time trial on a track. Then determine your vVo2 by using the following formula:

vVo2 = distance covered in meters/360.

For example, if you covered 1,500 meters in 6 minutes, your vVo2 would be 1,500/360 = 4.16 meters/second. To convert your meters/second to 400 pace, divide 400 by meters/second. In this example, 400/4.16 = 96 seconds. 96 seconds x 4 will give you a vVo2 mile time of 6:24. 85-87% of 6:24 is 7:21-7:31, which would be your threshold pace, and 75-80% is 8:00-8:32, which would be your aerobic threshold pace. You can also use a recent 5K to estimate vVo2. Simply subtract 20 seconds per mile from your 5K race pace to get a good approximation of your vVo2 velocity.

Tempo runs can also be done using heart rate as a guide. After determining your maximum heart rate (MHR), tempo runs can be done at 80-90% of MHR, with aerobic threshold runs at the lower end (80-85%) and anaerobic threshold runs at the upper end (85-90%).

Now to the fun part, designing a week’s training using your vVo2.

Devote a day to each threshold (anaerobic and aerobic) and keep enough easy days in between so you’re well rested. A general guideline is to start threshold runs with a 20-minute run. The best way to design any week of training is to start with the end in mind. What I mean by end is the weekend long run. (Long runs and recovery run pace can also be calculated by using 70-75% of your vVo2 pace.)

If you run your long run on Saturday, do your first tempo run on Tuesday. This gives you 2 days of easy running in between. Tuesday would be your threshold run day. Again, the 20-minute run doesn’t need to be run in a single bout. 4×5 minutes with 1 minute’s easy running, 2×10 minutes with 2 minute’s easy jogging. Wednesday would be a recovery run, and Thursday would be your aerobic threshold run. Since the pace of the aerobic threshold run is slower, this run can be longer in duration. The same rule applies in dividing it up into manageable segments.

As a coach, the hardest concepts to communicate are the ideas of progression and overload. When do I add minutes to the tempo runs? How do I decide when to do the threshold paces? Tempo runs can be done all year long. Be patient and allow your body time to adapt. The only way to answer the second question is to perform a new vVo2 test or mile time trial periodically–say, every couple of months.

Remember: always design your training with your goal in mind. If you’re focusing on a specific race–5K, 10K or marathon–decide where you want to be with your tempo runs in the weeks leading up to that event. Don’t try to do too much too soon. Training is like combining two paints to make a new color. Once you add too much of one paint, you have to start over. Developing a higher form of fitness comes as a result of training systematically at various paces both faster and slower than your target pace. Stress both aerobic threshold and anaerobic threshold and you’ll see the results.

New British Flag Without Scotland In The Union

New British Flag Without Scotland In The Union

I had a call from Garmin today saying that some Irish chap had been pretending to work for the5krunner blog and that ‘could he have a 920XT to review please?’. I’m sure he planned to return it.

Aspiring gadget thieves should note that it is actually fairly hard for most people to get scarce PR samples from the manufacturers and they verify addresses. Expensive bits of kit have to be signed for etc etc. And when I last looked there were certainly no Irish males here !

2014: || Garmin 920XT Forerunner || – Early thoughts for a review & upgrade from the 910XT

Garmin 920XT vs Garmin 910XT - Triathlon Showdown

Click to buy: otherwise just stare and marvel.

The 920XT is now more generally available in the UK as the pre-Xmas orders are fulfilled. The promises (hopes) of a wonderful new model by myself and others started to wear a bit thin on some ears in the UK as the product was only on sale in very small volumes, unlike in the US. Well now I can write this as we are all good to shop.

Review of the Garmin 920XT to follow in the New Year (2015)

To order one: click the watch image (above) or for a better deal use your British Triathlon Federation discount at the Garmin shop – the 25% saving will cover the membership fee!!

OK we all know that if you have a 910XT you will, for sure, want the newer 920XT. But is it worth upgrading?

Summary: The Garmin 920XT is for sure the best triathlon watch ever.

But will it make you a better athlete if you ditch the 910XT?

We’ll see if “probably not” really is the answer to that one. So I’m starting off writing something to help you rationalise that upgrade that you are going to make anyway :-)  Let’s consider that ‘must-have’ feature – that really is only nice-to-have but you, at least, sell the idea to your loved one who is going to buy it for your birthday/Xmas in any case.

If you have cash to burn and love gadgets you will, of course, have already bought one. You’re probably reading this to rationalise to your fellow tri-club member the reasons for your wise investment.

So I’ve started off a bit tongue-in-cheek, apologies if you don’t like that sort of thing, I will go through the key upgrade features as I see them. You can assume it does what the 910XT does and more. And, yes, I do have one and it’s great.

Must have or Good-to-have

  • Battery life. This really is GOOD (purportedly up to 40 hours in ‘UltraTrac’ mode). In line with the other manufacturer offerings. Even if your battery life degrades a bit over time then you will have enough juice for your Ironman or Ultra as well as turning on all the inbuilt bells and whistles. The battery life is WAY more than adequate enough for my needs; even if I forgot to charge it for a couple of days I would be fine. This feature certainly is perfect for having a gadget ready-to-go when you are…not true of the old 305!
  • Recovery Advisor/Recovery Time: Once your HR zones are entered this will work. It will tell you how long to wait until your next hard session. This really should be what we all look at after a session as we should not interfere too much with the adaptation process in order to improve. However it does not take into account swimming efforts at all. So: good to have but not fool-proof. IF you do duathlon this is a nifty little useful feature; a little less nifty for triathlon but certainly of some use.
  • Altimeter : I don’t really bother about the number of metres I’ve climbed. Perhaps I should. If I did I would find that, according to several sources, the altimeter has some accuracy issues that are dependent on the time to work out the altitude at the starting position (although Firmware v2.57beta notes improvements). However my reading of the problem is that if you leave the 920 turned on a lot those issues should lessen.
  • Current pace bug fixed: This seems to be a lot better. It seems usable!!. I’ve yet to really pay attention to current pace over all my training speeds but superficially it looks usable. This is a BIG plus for me as with the 910XT the current pace was unusable.
  • Proper bricks and indoor bricks : Brick workouts with the 920XT are mostly great. Finally I can create a custom run-indoorbike-run-indoorbike-run brick session. And wonderfully the GPS is automatically turned off for indoor bike on the multisport session. You certainly couldn’t do that with the 910XT where it had to be done manually and that manual process was a step backwards from the 310XT IMHO. Anyway It’s perfect now. Or is it? Well. no. There looks to me like a limit of 9 stages to a custom multisport session. Why? I can’t see why it shouldn’t be limitless for two reasons: sometimes I *DO* more than 9 stages (not often admittedly – say in a transition practice brick) and there is also the scenario where you press the wrong button a few times and zoom through the stages incorrectly whilst racing S-B-R-B-R-B-R-B-R-B-R…….. is the best setup to cater for errant fingers.
  • Auto footpod/pod calibration: I’ve not really properly looked at this yet. The 910XT’s 1km GPS calibration only worked for me if I (for instant pace) calibrated it at the speed that I intended next to run at. I didn’t find it as foolproof as others suggest.
  • RR HR when swimming. DCR reports that HR recording occurs in OWS mode but not indoor swimming mode. You must have an optical wrist strap like the MIO Link for this to work, this is good progress Mr Garmin! But we are still not quite there. So, basically, it’s easier but less cool to have a HR caching strap like the  WAHOO TICKR-X – no RR data though with the WAHOO cache :-( If you want RR data in a Garmin environment for swimming I suspect you will have to wait until Spring 2015 for the Suunto (!) belt to be supported by your smartphone’s Movescount app (you combine it later with your fit file) and even then I don’t know if you will get RR. You could use the PULSEON wrist device but I don’t think that is sufficiently waterproof.
  • Swimming Drills & rest periods: Super Nice!

Nice to have

  • Colour screen. My workouts are coloured in blood, sweat or tears. A colour screen will not help one iota. It’s OK. I have to confess to initially being confused by whether or not a menu option was highlight when I pressed ‘enter’.
  • Watch Mode: It can work as a watch for months (apparently) without needing to be recharged. Apparently lots of people wanted this. I didn’t but as I am going to use it as an activity tracker I might as well dual-purpose it as a watch and get my money’s worth.
  • Metronome: for technique improvement whilst running. Nice enough. Not a deal breaker.
  • Running Dynamics: This really is only nice to have. Albeit an impressive one. What in reality are you going to do with the number? You can’t really compare to other people and most of us will probably not track their improvement over time. This might be more useful for coaches. To be fair Garmin have researched runners’ stats and now do have guidelines but if your Ground Contact Time is too high then what are you going to do about it? Where is the next actionable step for YOU? OK you makes your GCT less, but how do you exactly intend to do that?
  • Cycling dynamics I imagine is imminent with Vector firmware upgrades. Perhaps this will be more of good-to-have as I personally think it might be more actionable, with the mechanics of cycling being much simpler than those of running.
  • It weighs less and is smaller. And it’s probably more aero. These things will not make any difference. Well being smaller it might be fractionally more easy to get a wetsuit off over it. I never had problems with the 910XT. Indeed in a race I often never bothered wearing a watch in open water.
  • Wifi and Bluetooth. These make things marginally easier for me managing data and bits of kit. I can and have survived without either for a long, long time. No doubt I will use them but they will not make me faster. I appreciate these are different for other people. Wifi improvements are in the pipeline and there are general industry moves to make bluetooth faster. NOTE: Bluetooth is only to connect to a smartphone; the 920XT will absolutely not, for example, connect a Bluetooth HR strap.
  • Ability to create workouts in your calendar online and to a degree manage some settings online. As sports watches get more complex this will become a more important must-have feature. Setting up alerts, plans and workouts on a small device is fiddly. I still find the online process a little more time consuming than I would like and often revert to just doing a session manually.
  • VO2 estimates: These are from Firstbeat so they should be accurate. In cycling mode you will need a power meter. But again what are you going to do with these numbers? Some coaches do set %VO2 efforts in sessions, many do not. VO2 *IS* a fantastic measure of how good you are (well vVO2 is at any rate) and it will/may improve gradually as you train more and then plateau. But it is what-it-is. IMHO it will play little use in my daily training or quarterly planning.
  • Recovery Advisor/Recovery Check: Gives you an indication of your immediate post-workout recovery. Interesting but I don’t think I would monitor that over time.
  • Bluetooth Phone Notifications To your 920XT: Really? I must be getting too old to answer texts when I’m running; come to think of it I don’t take my phone with me. Though on the other hand when on a mind-numbing treadmill session with headphones it might be good to know that someone is calling you to invite you out for a beer.
  • Activity tracker – well I’m going to use this lots. And it’s nice to have. But it won’t make me faster. At all.
  • Personal Bests – Why? Why would you want this on a watch? Why?

So: Really for me it’s only worth getting the current pace working and being able to have a GPS-free component to the indoor parts of some of my brick settings. I will use the drill mode more in swimming. That’s NOT a lot for £300+. But the 920XT is very good, very nice and  I am a happy bunny with it. Just a bit poorer!

Then again sell your 910 for £200 or thereabouts and you’ve paid £100 for an upgrade with a new 12 month warranty…that sounds MUCH better.

FWIW: I was offered a bigger discount from Garmin to buy the 920XT – I ended up buying it from the Garmin Shop myself with the British Triathlon discount – just like you can. I don’t run this site to make money, unlike many others out there.

Android support is on its way for Polar Flow App



I’m just surprised that companies devote so much of their resources initially to iOS. In the UK it seems to me that Android and iOS *SPORTS* users are fairly equal in numbers. Maybe it’s different in the US maybe it’s different across the whole population. It just really (well a little bit) annoys me that the Android version are either pared down versions or versions that are released 6 months later. Mild rant over.

 In reality this will be released in early 2015

————- Official Press Release Below ——————-

We wanted to give you a heads-up that Android support for Polar V800 and M400 will be part of FlowApp 2.0 release targeted for next week. This means that Android users will be able to enjoy FlowApp and its many useful features, such as easy wireless syncing, instant visual analysis and more. We know you’ve been waiting for this for a long time now, and we thank you for your patience.

We are working really hard to get this to you, fingers crossed that we don’t get any technical surprises which would prevent us from meeting the targeted December timeline. So please bear with us, we assure you this is our highest priority at the moment.

In the meantime, happy training!

What is the best HRM – Sports Heart Rate Monitor Comparison


, , , , , , , , , , , , , , ,


Source: me

I’ve tested a few sports heart rate monitors (HRM) recently and used many over the years. Here’s a quick post to say which I think is the best.

Firstly I’ve only looked at these from the point of view of sports-usage, rather than medical accuracy & usage. You’ll find a lot of Polar HRMs used by Sports Scientists and medical professionals.

For us sports people we need to look at what would be the best HRM for the gadget & stats world that we at least partly inhabit.

If that world is Polar or Suunto or IOS or Android then your ‘best’ HRM will need to support Bluetooth. Going forwards that’s going to be Bluetooth 4.

The Garmin world is ANT+, plain and simple.

Some older monitors would use proprietry or other analogue signals and some monitors will support both bluetooth and ANT+.

What criteria do I use?

  1. Accuracy & range & lack of spikes/drop-outs
  2. Comfort (which would include size and type of strap)
  3. Special functionality
    1. Wrist usage
    2. Data caching
    3. Multi-protocal/band signals
    4. Special data (eg cadence, ability to send RR/HRV and other efficiency measures of your technique)

Polar H7

  • What is it? Bluetooth chest strap.
  • What’s good about it? Accurate, comfortable
  • What could be improved? Other than its size there’s nothing that needs to be improved, it does what it sets out to and it does it well.


  • What is it? Bluetooth & ANT+ chest strap
  • What’s good about it? Accurate, special cadence and running sports efficiency, caches swim data, ‘tap’ functionality which can control music or lap markers. It starts caching data as soon as you put it on, so you don’t need to activate it with any other watch or device.
  • What could be improved? It could cache the RR/HRV data as well as the other efficiency data. It could makes its efficiency data compatible with, for example, the Garmin HRM-RUN.

MIO Link

  • What is it? Wrist based bluetooth & ANT+ strap.
  • What’s good about it? Can transmit an ANT+ signal to an adjacent watch underwater.
  • What could be improved? RR/HRV data may not be fully accurate, it could cache the data and a better display could be added. Battery life is fine if regularly charged but rechargeable battery life is always an issue to someone.

Garmin HRM-RUN

  • What is it? ANT+ chest strap
  • What’s good about it?  Accurate, special cadence and running sports efficiency. this is the most accurate of the Garmin series of straps in terms of drop outs.
  • What could be improved? Other than its size there’s nothing that needs to be improved, it does what it sets out to and it does it well.

Suunto SMART Sensor

  • What is it? Bluetooth chest strap.
  • What’s good about it? Accurate, comfortable, very small. Appears sleek and well-made. Caches data and later bust-uploads it back to movescount. Must initiate/terminate the exercise-to-be cached with a smart-device (currently iOS only) so it also exposes you to the risk that your smartphone will run out of battery while you are swimming.

I use a bluetooth based HRV app every day and I find it quite interesting how quickly and easily the bluetooth devices are found. The Suunto is VERY quick to be found and works perfectly 90% of the time…which doesn’t sound a lot but it is the best of them all, including the Polar. It is the most realible hassle-free connection IMHO.

In terms of accuracy all of these models are super-accurate for sports usage. The Suunto is the only one that regularly reports 0% errors in HRV data sent to FIRSTBEAT. But that does NOT mean that it is any more accurate for your normal Sports-HR recording. If you use HRV it might be important.

For underwater usage the TICKR-X is the most reliable all round performer. The Suunto appears good but if you forget to turn on the data recording you have to go back to your locker or bring MOVESCOUNT poolside somehow. The Polar is great underwater too. The MIO is OK underwater if you position it just-right but of course in the ANT+ world it relies on your Garmin being able to accept an ANT+ signal in swim mode (only possible in OWS mode on the 920XT)

For me the best strap is the WAHOO TICKR-X it does just about EVERYTHING I want a HRM to do in the Bluetooth & ANT+ world that I co-inhabit. It’s also great as it saves me having a cadence sensor on my bike and it’s great that it gives me running efficiency data. However the only reasons why this product is not perfect is a. It’s a tiny bit big (fair enough for what it does) and b. it does not support Garmin 620/920 protocols to display those metrics and c. it does not store all the special data so I would be tied to a smartphone to see that data. And me relying on a SMARTPHONE is never going to happen. So, just change those last 2 points and it will be the only HRM you will ever need.

So I revert back to my early morning Suunto for getting my HRV right first time, every time. There are also a few glitches in the smartphone app that mean that I cannot YET rely on the Suunto for swim data usage.

For others who hate chest straps the MIO is an obvious choice. HOWEVER the imminent MIO FUSE will provide VERY significant updates to what the MIO LINK offers and will make it a much more attractive device. Review to follow.

Really wrist based caching of accurate RR swim data is the only way to go for innovation in the swimming world. I don’t think we will get there quite yet. (I haven’t tested the MIO Fuse though)

Interesting: Only the Suunto tells me (on the app) what the charge of the battery is. What a great feature! Such an easy way to eliminate the battery as a cause of any problems you might be experiencing.

Boring: Or you could just use one of the really old Garmin hard straps. Cheap as chips and reliable.
