I'm thinking of doing a "Spartan Race" in August. I've only recently learned about it but it sounds like so much fun......also outside my comfort zone, which is a good thing. I love trying new things. Basically it's a 5km obstacle course race. You climb, crawl, balance, throw things etc. My only concern is that this will be 2 months before my half ironman in Miama and I would hate to injure myself and jeopardize my race. Hmmm.....I'll have to think about that one.
