GROC Genesee Regional Off-Road Cyclists

This is a women's only race that supports breast cancer, along the lines of Tough Mudder.  It holds several races across the U.S. and one of the races is being held in Buffalo, NY.

Run, walk, climb, crawl—you will experience it all. With obstacle names like H2OMG and PMS (Pretty Muddy Stuff), you can expect to laugh until your cheeks hurt. But don't worry, if you get to an obstacle that's more than a challenge for you—hey, take one of the detours.

Also expect safety throughout. Expect the competition to go on rain or shine. Expect not to be timed. Expect some crazy team uniforms. Expect to leave with an overwhelming sense of accomplishment. Now, check out the website for more info!
