About this race

The Maine Summer Adventure Race is an annual event designed to showcase the most beautiful, interesting, and fun parts of Maine. Self-supported teams one to four travel nonstop on an unmarked, linear course via mountain bike, foot, and boat, navigating by map and compass. Adventure racing is the ultimate test of endurance, strategy, and teamwork, which is why this race is known as "The hardest day in Maine."

The 24-hour race will begin at 10 a.m. on Saturday, July 11 and will end at 10 a.m. on Sunday, July 12. Check-in and map hand-out begins at 8 a.m. on Saturday.
