Bimbler's Bluff 50k

Bimbler's Bluff 50k takes place in Guilford, Connecticut, on October 18, 2026. The event offers a single format, a 50K (31 miles) trail race that starts at 8:00 AM. With one distance on the schedule, the whole day is built around the ultra field, and the mid-October date usually means cooler temperatures for a long day on foot in southern New England.

A 50K is the classic first step into ultrarunning, and this one sits at a manageable point on the calendar: you can build through late summer and early fall, then race before the cold sets in. Plan on a 16-week block that progresses your long run toward 20-plus miles on trails, with hill repeats to prepare for the ups and downs the name suggests. If you already have marathons behind you, treat this as a chance to practice fueling and pacing over rougher ground rather than chasing a road-style split.
