Mapmyride - Calories

[AndyBrew]

Just used my mapmyride for the first time and it hasn't calculated my calorie usage, anybody know what I may have missed??

The only thing I haven't set is the resting heart beat as I have no idea what it is.

not sure why its not working for you but does anyone have an idea why there is such disparity between the calories burned on strava and map my ride?

Both are guesswork
