I know the calculation of calories burnt isn't an exact science and different sites use different algorithms, but I'm looking at a bike ride I logged with the Fenix 2 yesterday and Garmin Connect is saying I burnt 1,032 calories while Strava reckons it was 634! Why the massive discrepancy? I've got the same personal profile set up on both sites. Surely a 40% difference has got to be down to more than just a variation between calculations? If not, these algorithms must be next to useless!
That is interesting, as when I run with a HRM I typically get 100kcal per 1km on Strava and around 70kcal per 1km with my Garmin device. Which is a massive differential albeit the opposite direction.....
