I don't have many chafing stories, I have been lucky. The one I do have is not pleasant. I think I have told it before. During the 2016 Disney full I wore my water belt. I normally wear it with the pouch that holds stuff in the front. Never had a problem in any training run or race prior to this one so no big deal. Well, for whatever reason, maybe because I was drenched from the humidity before we hit MK it was different. Well, think about wear that pouch would rest while sitting in the front and what it might rub on for 27 1/2 miles during that race. I couldn't feel anything wrong because I was sweaty I guess. Needless to say, that shower back in the hotel was not fun. For the record, I wore the belt so it faced the back this past year and I did bodyglide my friend down below just to be safe as well. Sorry if that was TMI.
