From the Organizer
Join us for the 5th annual Island 25 or Island 15 Bike Race on Howland Island- part of the Northern Montezuma Wildlife Management Area on Saturday, June 6, 2026. A great warm up event for the Black Fly Challenge the following week.
Riders of both the Island 25 and the Island 15 will start at the Savannah Fire Dept. (corner of Rt 89 and Savannah Spring Lake Rd). There is lots of free parking. Helmets are required to be able to participate in the races. The event will be capped at 250 total participants.
In order to uphold Safety and Integrity Standards, this event will exempt from participation any athlete/individual officially sanctioned by either Safe Sport or the WADA (doping).
This year's participant giveaway will include a custom tee shirt.
