The ride to work was 19 miles and i average 16.1 miles per hour and 7 of the miles was on a gravel trail. THe ride home was 11.1 and I average 16.3 home. First time I have double commutes above 16mph avg. I am not sure where the speed came from but it sure was fun to ride fast.
I rode in this morning average 15.7 and I felt slow

I average 10 mph.
I'm still new to bike commuting. My ride is only about 12 miles each way, but my stamina isn't great so I try to save my legs for the couple of sprints that my commute requires, and the climb up the hill to my house. When a descent gives me a boost though, I do shift to the highest gear on which I can easily pedal without mashing to sustain my speed until the momentum runs out.
