Accuracy WAY off?!?!

[John1422]

I've recently had the same problem with my Surge. I rode 32 miles today with a lot of hills. My average heart rate was 89,117 max and burned 969 calories. It seems like the accuracy has been falling off fast.

Welcome to the Community @John1422! I recommend performing the restart follow the instructions on this post, this will help to improve the accuracy of your tracker. I also recommend checking this great post in order to learn more about the heart rate data. 

Hope it helps!

I rebooted it twice within a day before that ride, once since then. On a 26 mile ride yesterday Fitbit recorded 26.06 miles, Map My Ride 26.56 miles. Fitbit showed 1250 calories, which is better than 969 it computed for the earlier 30 mile ride, Map My Ride figured 1705 calories for the 26 miles so it's still way off. The heart rate also seemed more realistic thougy, 127 average for the 26 miles.

Hey there @John1422! The algorithms that MapMyRide uses are different from the algorithms that Fitbit uses. The inaccuracy that you're experiencing is from the calories, the distance or the hear rate? 

I recommend choosing if you want to track your ride with MapMyRide and add it to Fitbit you can link you exercise to your Fitbit account check out the integrations that we have available on this site. 

Catch you later!
