I did the one in PA. It was 12 and a half miles. I didn't train for it besides my normal workout schedule and a bit of running. I hate long distance running but wanted to do it regardless. My boyfriend trained very hard for it. Ran up to 12 miles a week. So if you enjoy running train for it. If not good luck and hopefully you can muscle through it. Hah.
We finished in 4 hours and I suffered from cramps, torn toenails and bloody knees and of course, a lot of mud. Everywhere. Not too bad. The obstacles weren't too bad but it was the running that did me in as to be expected. The hardest obstacle was probably the tallest wall considering I'm short and by that point I was extremely exhausted.
I loved it but at some points I didn't think I would finish so it's awesome that I did. Even if I was limping across the finish line.
You have to dress up. We wore this:
We were just going for ridiculous..but somehow people knew we were gay? Got a few weird looks and a few high fives. As life goes I guess.
