Well, today I noticed that the real cold is bothering me more than usual. I think maybe because it was so freaking warm this year. And i didn't even ride today! I just have to acclimate. I, also am no longer a desert rat, after 20 years. I have the right clothes, too. But I think I've reached my outer limits for riding, in low 30's. I don't think I would like my hair freezing. What's the point? Being miserable is not my idea of fun. I ran on the treadmill in my nice warm loft today.
It's just that weird time of year between the end of the better riding weather (i.e. 40s) and the beginning of the nordic ski season. Hey, in 4 weeks, today's temperatures will feel balmy.
