Here is a link to the Palmetto O-run Challenge. It is similar to the USMC Mud Run, but without the mud. I ran in the inaugural race last year, and it was very good. The best thing is, that there are (were) way less teams than the Mud Run. It's less crowded, less dirty, and just as fun. If you are into this kind of thing, you will really enjoy this one. I plan to be there. Come on out and lets race.
