My favourite kit and nutrition
- Maurten — the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter — the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck — the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 — front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 — radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd — the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 — the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.

Such a pleasure to see ST3 is still being used for analysis by t5kr.

I do have dcanalyzer software ready as backup for when st3 stops working
Hi,
interesting articles. I have use the 1030+ for a couple of weeks now. Before I had the 810. I experience Strava segment problems with the 1030+. During a 33km/h cruising speed ride I have multiple KOM’s with 50+ km/h. Very annoying. Like 70 km/h average with a max speed of 27 km/h.
Could it be the GPS settings?
hey, yes that is seriously wrong. Apart from obvious questions like…were you in a car a little alter on i can’t see a sensible explanation for this.
STRAVA do adjust segmeent performances and i guess it’s possibel that your gps might have incorrectly recorded the start/end of the segments.
For elevation accuracy, the only way to test would be using LiDAR data. There is wide variation across devices – I have found that Garmin Edge devices are good, as are Wahoo, but the latter does more smoothing and the former gives more unsmoother raw data (I prefer that). I have some detail on adding LiDAR data on YouTube:
See videos 7 and 8 https://www.youtube.com/playlist?list=PL_xiJBvuN7zdfaGEqojYI9HySrXUpEh27
And this one too:

Also calibration of the device should be turned on, but not on as riding when riding the segment for comparison if you want all data to correlate, if you see what I mean.

hey there, thank you for those links and your comment
surely though the 10m tiles will only be accurate if your gps can put you in the right one. eg on very steep hills that will be a problem as will urban canyons.
do you know the tile sizes for garmin’s DEM model?
Good point! I wasn’t using it that way, as I was creating a route. You can go down to 25 cm squares with good data, but as you say, to truly compare, that’d need the device to put you on that square.
Garmin’s DEM via Garmin Connect follows SRTM fairly closely. Strava’s is most refined.
