37F (3C) this morning. Ifind it so much harder now to maintain a good speed that I would on my road bike (i'm on an old mongoose hilltopper SX MTB with slick tires). I think it has something to do with positioning. I don't feel the same muscles working, and I just don't have the same power. My 80PSI tires feel like they want to hug the asphalt, and the clothing I have to wear feels very restrictive... Not to mention the inscreased gear I gotta carry because of weather.
Ah well, I guess I just gotta keep on riding, and try to adjust my position. Winter's going to be hard, but I'll keep on biking. I had a good workout, and that counts for something, right?
