About
TARC Wapack and Back is run on May 8, 2027, in Ashburnham, Massachusetts. The 50-miler (80.5 km) and the 43-miler (69.2 km) start together at 5:00 a.m., and the 21.5-miler (34.6 km) follows at 9:00 a.m. Elevation gain is not listed.
A 5:00 a.m. start means the first hour is run by headlamp: put at least two night runs into your build-up so the narrow beam and the slower, more careful footing feel familiar. On rocky New England singletrack, average speed drops well below road pace, so plan your day in hours of effort and aid-station splits rather than in minutes per mile and you will finish far closer to your estimate.
