If that is the case, you were at a steep calorie deficit and did not have enough energy to fuel your ride.
I rode 20 miles that day.
I did the same ride again on Monday. Averaged 17.6mph and heart rate was normal for the effort I put in. The fact that my performance was down for one day isn't a big deal. I am just trying to understand why, so I can use that knowledge to make better choices in the future.
