Half Marathon Ideas (costume encouraged)

k7n2w3

In 2 weeks, a friend and I are "catching up" by running a half marathon together. Costumes are strongly encouraged and I am hoping to gather some ideas because a costume party is one thing but we have to run 13 miles in whatever we choose and there are also obstacles that we have to do but from what I hear they aren't like military ones, more like running through a bounce house, water balloon fight, that kind of stuff.

I just ran Broad Street in Philly but took it as a challenge for a personal record but this is to be a fun run (while still getting 13 miles in for a run that day) that advertised basically "costumes recommended, fun obstacles, free beer at the end, and a free massage"... those qualities just can't get anymore fun haha.

Any fun costume ideas? keeping in mind there is 13.1 miles to be run in it, i think they spray you with hose/water balloons at one point so water is involved, and there might be things to climb :-) (i'm sooooo stoked for the run but def want a fun costume too!)
