Bimblers Bluff 50k

Guilford, United States • 18 Oct 2026

Bimblers Bluff 50K - Guilford, CT

The Bimblers Bluff 50K is an off-road foot race that begins at Guilford Lakes School, 40 Maupas Road, Guilford, Connecticut, and travels through several inter-connected woodland preserves in southern Connecticut. The route is composed entirely of rolling forest roads and single-track trail that can be extremely rocky, so footing varies throughout and sections demand careful navigation.

The course is laid out as a point-to-point or connected route rather than repeated identical loops, which distinguishes it from many local events. Organizers note the race is intended to combine adventure with sustained effort, and recommend entrants have recent long-distance running experience such as a road or trail marathon.

Aid stations are provided along the course. Cutoffs are enforced at named aid stations and at the finish to ensure participants are off the course before dark and to allow volunteers to conclude their duties. Entry fees increase as the event date approaches, with tiered pricing that rises from lower early-entry amounts to a higher race-day price. Limited spots are available and volunteer support is used to staff the event. Visit the organization's website for the most recent information.
