Bimblers Bluff 50k

Guilford, United States • 19 Oct 2025

The Bimblers Bluff 50K is an off-road trail race held in southern Connecticut, starting at Guilford Lakes School. The course traverses several interconnected woodland preserves, featuring rolling forest roads and single-track trails that can be extremely rocky. Unlike many ultras, the route does not require multiple loops, offering a unique adventure and challenge that tests both fitness and mental stamina.

The event is suited for experienced runners, ideally those who have completed a recent marathon. All participants receive a goodie bag, and finishers within 10 hours earn a special award. Proceeds support local land conservation efforts. Visit the organization's website for the most recent information.
