Calories burned cycling
I went on a ride yesterday with my wife and went on the same ride today by myself. Both rides almost duplicate of each other except for the intensity. How is this calorie burned so little difference?
Yesterday 20 mile 1 hour 37 minute with average speed 12.3 mph. Calories Burned 563
Today 20 mile 1 hour 14 minutes with average speed 16.1 mph. Calories Burned 586
