For the first two years of its existence, the Notchview Ultra was a 6-hour fatass-style event where the top mileage tallies were in the mid-30s. When the event added 12- and 24-hour options for 2017 and 2018, Dietmar Bago was the standard setter with 91.2 miles each time in the event’s longest offering.

In 2019, the Notchview Ultra entered new territory as race director Benn Griffin expanded the format into a multi-day distance fest that included a 72-hour race. In doing so, Griffin dared runners to dream of the endurance possibilities and discover what was possible on the 1.9-mile cross country ski loop at Notchview Reservation in Windsor, Mass. Ann Alessandrini was the first to set her sights on 200 miles, and she blasted through the distance barrier in the final hour to close out a 201.4-mile effort. It was the first time a runner would surpass 200 miles at Notchview, but not the last.

The Berkshire Ultra Running Community for Service (BURCS) played host to the 10th edition of the Notchview Ultra on July 11-14, 2025, at Notchview Reservation in Windsor, Mass. Runners took on a distance-specific 100.7-mile race or time-based 72-hour, 48-hour, 24-hour, 12-hour and 6-hour ultras on a 1.9-mile cross-country ski loop course.
