Solo ride at lunch from work, extended loop out to Poway Rd and back. The day was a nice one for riding, with little wind to deal with. I felt pretty good and rode at a good pace. Of course, this route has no real climbs, which helps with the average speed.
Avg. speed = 18.6 mph. Total mileage = 16.5 mi
