Anyone else like to participate in Tough Mudder events in your area? Do you have a favorite obstacle? I'd have to say mine would be the rings. My least favorite is probably the jump from the 20' platform into the cold water. Boy do I dislike heights... I did the Twin Cities (Sommerset, WI) event in May and I've signed up for my second one in Cascade, WI which is scheduled for Sept 9. I'm so stoked! I love to train for these things and I always get super pumped when I watch their 2012 promo video.
