You should have pooped beforehand and you could've been lighter on the feet. 
How high are you??
I remember running a half marathon, having gone to the bathroom before, then going FIVE TIMES in the space of 90 min or so after finishing the race. Irritable bowel syndrome is a b---h and sometimes you're so down you want to end it all.
If you're going to do a spin off thread, pick one that more people have posted in so they know what you're talking about lol.
