A couple of weeks ago I rode at my coldest temps, low 20's. Surprisingly it was dh idea. Despite my Gore Windstopper my fingers were frozen by mile 10 and ached. This is a club ride that I lead, not that there were many to lead, but I ride at a slower pace so accomodate.
Although others faired not too badly, I wasn't going fast enough for my body to get warm. I will resume leading the rides when temps get warmer needless to say. I also ended the ride at 15 miles since I couldn't take much more.
