If you feel like you want to be one of the Dirty Dozen, we've got a mission for you! This mission is of the ultra and mentally challenging variety: the ultra part is to run 50k, the mental part is to do so while doing 12 hilly loops in Forrest Park.

It’s one of the tougher ultra-races in New York City, a city that can be an ultra-challenge in and of itself. Are you crazy and/or tough enough to be part of the Dirty Dozen? If so, we’d love to see you accept the challenge and join us on September 9th! The race will begin at 8am and has a time limit of 8 hours.
