Have seen this, never done it. Won't be doing it this weekend I am off to do the half at the Flying Pig in Cincinnati. I agree I hope for COOL weather! Reading the stories on CMM last weekend doesn't make it sound to appealing. I also had a friend run the Glass City in Toledo last weekend... he said it was pretty bad. Lots of DNF's, he even sent help for two different people sagging by the road between aid stations. If it is that bad, lots of walking coming up!
