Started at base of Monadnock and climbed Old Toll Road to summit of Monadnock. Followed W-M trail from summit of Monadnock west to finishing point at parking lot of Mt. Wantastiquet. 47.3 total miles from base of Monadnock to finish. Technically W-M trail begins/ends at summit of Monadnock. Took 45 minutes to summit Monadnock (2.1) miles, so time for W-M from summit of Monadnock to finish is 10:52, according to Strava.
Support: Cached aid at points throughout. My wife and kids met me in downtown Keene with a water bottle and moral support, then again at the entrance to the Horatio Colony trails with my hydration vest. They also dropped a cache of water and pizza for me at route 63 crossing. Otherwise, I ran alone and self-supported.
