Nestled in the foothills of the Green Mountains, the Peak Races Mount Sparta 24-Hour Challenge is hosted in the rustic New England town of Pittsfield, Vt.

Just down the road from Killington, the Riverside Farm foothills offer up to over 1,000 feet of elevation gain with a course of just over a mile. In this self-supported event, participants will have 24 hours to be the last person standing as top male or female.
