Notes
Pemi Loop in the White Mountains of New Hampshire. 51k loop, plus a 2k detour at the start looking for the trail.
Overall a great run. Felt really strong after the first 1/4, was going at ~10 hour pace, the next 1/4 was really hard (steep and rocky) slowed to a ~16 hour pace, the last half was pretty quick. Very hard trail overall, around half way the up hills really started to hurt, luckily most of the elevation gain is done in the first half.
Felt surprisingly good afterward and am not terribly sore the day after.
