I'm just shy of being a Clydesdale (199 lb) and just took up cycling. I've used MapMyRide and Strava to count the calories I burn.
I typically ride flat terrain at 14-15mph and both apps are telling me I burn 1000 calories approximately every 15 miles.
Now my online life coach (part of my health plan) says that's not correct and I'm way over-estimating. But how can both apps be so wrong?
