I'm not much of an endurance sport person but nothing gets me going like CC skiing. But then again nothing gets me sweating like CC skiing. I think the cold winter really exacerbates the problem too. If I can I do a warm up lap before a big one and strip off my heavy layers. Otherwise I wear things with zips so that I can vent easily. I always keep my ears covered but not with anything too warm. Sorry that is the best advice I can give.

I have a question though, does anyone have a recommendation about balaclavas. I just bought one and it is nice until I warm up, then I pull it down so that it is only keeping my head warm. But because I was breathing through it, it is all wet and gross. Any ideas as how to avoid this grossness?
