Spaulding Woods 50K

The course is a technical 5.6-mile loop trail filled with rocks, roots, and foot bridges. To finish the full 50K each runner will have ten hours to complete six laps, or approximately thirty-four miles and 4.2K feet of total gain. The course is over 90% singletrack with a small portion of doubletrack. You will have access to a well-stocked aid station and your own drop bag as you complete each lap.

The race begins on the Spaulding Academy & Family Services campus, 72 Spaulding Rd in Northfield, NH. Bib pickup is between 6:45am and 7:45am on the day of the race. There is a ten-hour time limit to complete the race and a strict 4:00pm cutoff to begin the last lap. Any runner not on their sixth lap by 4:00pm will not be permitted to continue. Dropouts must check in at the timing table prior to leaving the event.

To minimize the race’s impact on the trail system, pacers are not allowed. This is a cup free event, please bring your own refillable water containers to help avoid excessive trash. For safety we do not allow dogs, strollers, or drones and discourage the use of headphones while running.
