Trying to get some handle on calories burned. Looking at online estimators, MFP, Strava and MapMyRun even- the estimates are all over the place. Anyone have any data or info they can share from a power meter?
As an example. Today I rode 18.77 miles in 1:19:40. Very flat. Avg speed was 14.1.
Strava: 550 cals
Bicycling magazine:1026-1300(depends if I pick 12-14 mph or 14-16) I would split and say like 1150
Spark people 1114
Just a few examples. As you can see the numbers are all over the place.
Trying to get an approx. like if someone says for example 30 or 50 or 70 cals per mile - something like that
