Today my husband & many of my friends are running in the Warrior Dash. At the beginning of this year a zillion of us signed up for this race. I ended up selling my ticket because, well, pregnancy is a really good excuse to not do it! From what I read in the rules, they won't ban you if you're pregnant, but truthfully, even an extremely fit pregnant woman probably shouldn't be doing these obstacles.
The least scary obstacles appear to be jumping over fire, crawling through a mud pit under barbed wire, & dashing down a river. There is also the 'Deadweight Drifter' where you walk through waist deep water & go over logs as your obstacles (because apparently waist deep muddy water with 1,000 diseases in it isn't enough of an obstacle). And the hardest (to me) it looks like is crawling across tangled nets. As in, don't fall, or you're screwed.
In 3.56 miles there are 12 obstacles. Twelve. And it appears that 10 of them are in the last half of the race.

So wish him luck, and please say a prayer that he makes it out okay without needing medical attention!
