The Hamsterwheel Endurance Runs

The Hamsterwheel is a timed ultra event organised by Just Keep Running, LLC in southern New Hampshire. Editions take place in November at the New Boston Fairgrounds. Recent events include the 2025 edition and a listed event on November 7-8, 2026.

Course and format

The event uses a repeated loop course that the organiser describes as a lollipop loop of four-mile length. Runners complete that loop multiple times as part of the timed endurance format. The event is presented as an opportunity for experienced ultra runners to accumulate mileage and for less experienced runners to attempt longer distances in a timed setting. Organisers and participants frame the race as a community-focused weekend that brings people together around the endurance format. Visit the organization's website for the most recent information.
