Usually from 11 mph to 13 mph depending on which bike, and the weather and wind conditions. Much slower in deep snow.
Then there are variances in stamina from day to day dependent on sleep and diet, etc.
Also, what's happening at the end of the commute? Do I need to take it easy to be fresher and more energetic afterwards, or can I give it my all?
