You have probably heard of tapiriik.com, you can sync all the following fitness/sports data services, shown in the image below, to your heart’s content
Tapiriik

Of course you can, for example, avoid the exorbitant $2 a year fee and link the likes of Garmin and STRAVA directly together. But those direct service-to-service links are far from available in every possible combination of sports data service.
What I specifically like about Tapiriik though is the ability to sync to DROPBOX. One of my sidelines is age group duathlon coaching (tri too) and a great way for other people to get raw data files to me is through dropbox. My athletes can automate that with tapiriik…cool.
You already knew that. You are a clever bunch.
But there’s no Polar on that list above, is there? There’s no Suunto either (Movescount & sports-tracker).
syncmytracks
Sync your tracks? Sync my tracks? This one does a similar syncing job on different services. Oh. Look here they support Polar and Sports Tracker (Suunto).


Some kind person even wrote about it in a bit more detail here…
Be careful though. This one will set you back about £2. That’s something like $3. Probably not worth it. Probably best to keep doing it manually 😉
FitnessSyncer
These products are all a bit confusingly named aren’t they? I mean, what could FitnessSyncer possibly do?
Oh, exciting. Suunto are in this list too 😉


Note: Eric at FitnessSyncer supports a LOT more services than the ones shown in the image above and it’s worth checking out if you have more unusual requirements.
Some More Suggestions
GC can automatically update itself from a dropbox folder as well as directly from some online data sources.
For those of you who might prefer an online data analysis platform then you could look at sporttracks.mobi which is continually improving.
Or you could check out Runalyze.com (link out: https://runalyze.com/). That a great-looking analysis platform. Indeed they prompted me to write this post as they announced today that they are supporting direct linking to Polar Flow. Flow is good (I like it) but it has its limitations.
For those of you who bothered to read this far (thank you) and the latest snippet of a rumour is that the Polar Flow app MAY be being redesigned this year ‘for some reason‘. I will leave the ‘some reason’ to your imagination.
Oh oh oh Polar goodies!
