I'm one of 'those' people, who use the commute for a good workout twice a day. The distance is short, less than 8 miles and I usually make the ride in less than a half hour. I have access to a shower/change of clothes at work, so I really work out! So I have been checking my average speed and distance on the commute and loading it into Bike Journal. Since I began riding my bike to work in January, my average speed for the trip has gone up to around 16.5-17 mph most days. That includes a fast three mile trip along the highway in the bike lane, and then residential streets, crossing the main drag in town, three intersections controlled by traffic lights and another half dozen stop signs that I normally roll through if the way is clear (in residential areas). So, how fast do you commute on average????
