About the race

New Boston, NH hosts The Hamsterwheel, an 11th-year ultrarun along the New Boston Rail Trail by the Piscataquog River. The course is a continuous 4.0-mile loop that is largely flat with one minor speed bump, starting near the Hillsborough County Fairground and turning at Lang’s Station. Runners may choose 6, 12, 24, or 30 hours, with relay and team-entry options.

Pacers are allowed after dark for longer races; crews and tents are welcome; dogs are not allowed. A central aid station provides water, electrolytes, real food, and gels. Finishers earn a belt buckle, solo or with a team, with chip timing. Visit the organization's website for the most recent information.
