BIG DAY RUN OFF - Gorham, NH
BIG DAY RUN OFF is a trail half marathon held in Gorham, New Hampshire, with the start and finish located in the parking lot of Big Day Brewing. The course covers approximately 13.1 mi(ish) and uses the Coös Trails Network.
The majority of the course is singletrack trail. There are three short non-singletrack sections: a 0.1 mile paved connection between the brewery and the trails, a 0.6 mile gated gravel road about halfway, and a 0.6 mile woods road near the end. Some short trail segments and intersections are shared between outbound and inbound runners and will be marked. Participants may cross paths with mountain bikers, hikers, and other trail users.
Course elevation begins near 800 ft with total elevation gain of 1,508 ft and total elevation loss of 1,464 ft. There are tentative plans for two aid stations located near mile 5 and mile 9.
Event logistics note ample parking at Big Day Brewing and on-site access to water and indoor facilities. Water, coffee, and snacks will be available before and after the race. Bib pickup is available on race morning and day of registration may be accepted if bibs remain. Podium results and awards will be presented after sufficient finishers have completed the race.
Proceeds from the event support the Coös Cycling Club stewardship efforts on the Coös Trails Network. Photos from the 2025 event are available. Visit the organization's website for the most recent information.
