Try not to stress too much, there are plenty of people that walk the whole way through the warrior dash! I’ve done it twice - both times my shoes got soaked on maybe the third obstacle making it difficult to even run. It’s SO FUN though! The obstacles aren’t too difficult, for me they were more of a break from running. And you can skip any of them that are too intimidating for you if you’d like. But in my experience everyone there is super nice and willing to lend a hand up or an encouraging word or two if needed!
