Chubb Bermuda Triangle Challenge
Hamilton, BM · Sunday 19 January 2025
Held in Hamilton on the island of Bermuda in January, this race takes place in one of the Atlantic's most distinctive settings. The island itself is small and densely populated, with a subtropical climate and a landscape shaped by limestone and ocean. The race weekend draws runners from around the world to experience Bermuda's particular character, where colonial architecture, lush vegetation, and the constant presence of the sea define the environment. The event has deep roots here, having grown from a modest seven-person affair in 1975 into a signature race weekend that the local community embraces. The full marathon course covers 42.2 kilometers of trail running over moderately hilly terrain. Runners will navigate elevation swings of roughly 250 meters across the route, with the highest points reaching around 39 meters above sea level and the lowest dipping to about 5 meters. The trail surface means footing demands attention, and the undulating profile will test your legs more than a flat road race would. Expect a workout that's neither punishing in terms of vertical gain nor completely forgiving, with enough climbing to keep you honest and enough rolling sections to find rhythm. The island's compact size means the course weaves through Bermuda's various neighborhoods and natural areas, giving you a real sense of place rather than an out-and-back or loop that feels generic.

Surface Type: Trail
Chubb Bermuda Triangle Challenge is a trail race, meaning the course includes unpaved surfaces such as dirt, gravel, or forest paths. Trail surfaces are inherently slower than road courses due to uneven footing, technical sections, and often steeper gradients. Trail-specific shoes with good grip are recommended, and runners should expect a finish time 10-20% slower than their equivalent road marathon time.
