Butterfield Mile, BF&M 10k, and PwC Bermuda Marathon

3 Races, 3 Days, 1 Beautiful Island

26.2 miles not enough to satisfy your passion for running and adventure? We’ve got you covered. The Chubb Full Bermuda Triangle Challenge offers participants the opportunity to run 33.4 miles over three days. The fun begins Friday night with the Butterfield Mile, then continues on Saturday with the BF&M 10k Run & Walk, culminating in the PwC Bermuda Marathon on Sunday.

During the event weekend, you’ll experience the best that Bermuda has to offer, including the island’s ONLY nighttime race in downtown Hamilton, beautiful courses that feature some of Bermuda’s most scenic beaches and architecture, amazing on-course support and entertainment, plus a post-race party on Sunday that is second-to-none.

3 races, 4 amazing one-of-a-kind Finisher’s Medals, and 3 days of fun!

Participants in the Chubb Full Bermuda Triangle will receive a 2023 Chubb Bermuda Triangle Challenge technical t-shirt (men’s and women’s sizes available), a high-quality branded jacket*, four custom 2023 Finisher’s Medals (one for each race and a special challenge medal), custom finisher’s certificates for each race, a swag bag, and a virtual race bag.

In addition, everyone is invited to celebrate their accomplishments at the post-race Finisher’s Festival in Barr’s Bay Park, featuring music, free food and snacks (including Oscar Mayer hot dogs, Nature Valley granola bars, and Haagen Dazs ice cream) courtesy of Butterfield and Vallis, locally brewed beer courtesy of Bermuda Craft Brewing, and rum cocktails courtesy of Gosling’s.

Participants that register online after November 1, 2022, or wait to register during the Race Expo, will not be guaranteed the correct sized technical t-shirt or finisher’s jacket. Register early to avoid disappointment! Please note that Challenge participants and people that register for more than one race (e.g., the 10k and the half) will only receive one shirt.

*Jackets run small in the women’s sizes. We recommend sizing up one full size to ensure a comfortable fit.
