Bimblers Bluff 50k

Guilford, United States • 18 Oct 2026

Bimblers Bluff 50K : Guilford, CT

The Bimblers Bluff 50K is an off road foot race held on October 18, 2026, that begins at Guilford Lakes School, 40 Maupas Rd, Guilford, Connecticut. The route passes through several interconnected woodland preserves in southern Connecticut and consists entirely of rolling forest roads and single track that can be extremely rocky.

The course does not require competitors to complete the same loop multiple times. Organizers describe the route as an adventure that requires both physical fitness and mental stamina; entrants are advised to have recent running experience such as a road or trail marathon. There are aid stations along the course and time cutoffs at several points to ensure all participants are off the course before dark.

Entry fees increase as the event approaches, with different pricing tiers listed for early, regular, and late registration, and there is a race day price. Spots for the 50K are limited. Volunteers are sought to support the event for those who cannot or prefer not to run; volunteer opportunities are available and are used to staff aid stations and other race functions.
