Yeah, a lot of people confuse overreaching with overtraining and get all freaked out. I don't think I know anyone who's ever overtrained, and I know a number of people who ride PBP and LD races. Most folks are sane enough to back it off when they find they're riding 2 cogs lower than usual. Occasional overreaching is fine. In fact if you don't, you don't know where your limits are. We just try not to do that in the middle of the season.
