Well my rides to work and back this week so far have been wonderful. I have been trying to keep my speeds at nothing less then 15 mph, with a avg. high speed at 29 mph [down hill at one point of my trip into work. ] coming home up the hill I am getting avg. speed of 12 mph. then after leveling off I can get back to 15 mph. Cars have been a little heavy, but all have given me the space need to make me feel good about riding.
