Thanks. Right now I like having something to train for and they are a new challenge. I recently saw an article that said these mud races and other races (triathlons, ultra marathons etc) are the new mid-life crisis. If so, it's more productive and cheaper than buying a Corvette! We are thinking about doing Polar Rush, which is in February at a ski resort. Their promo video makes it look fun but if we get a cold, windy day it could suck. I squatted this week for the first time in months. Felt good but I only did 115x5.
