The Maine Summer Adventure Race is an annual event designed to showcase the most beautiful, interesting, and fun parts of Maine.

The 3-hour race, with mostly on-trail hiking and optional mountain biking, is a perfect introduction to the sport for those new to adventure racing. Past finishers have included toddlers and septuagenarians. There are still plenty of spaces open for this course! 

The 8-hour race includes hiking, road biking, optional mountain biking, and sea kayaking. It’s a manageable challenge for anyone willing and able to spend a day roughing it in the woods (provided there’s food and beer waiting for them at the finish).

The 24-hour race is an extreme challenge, involving multiple hiking, mountain biking, and sea kayaking stages. Teams race through the day and night (and day again), covering 50 to 100+ miles in total distance.

All three races are hosted and designed by Kate and Cliff White, the founders of Strong Machine Adventure Racing.

The 3-hour race fees are $50 per adult racer and $30 per youth racer.

Registration fee includes:

  • Boat rental fees (8- and 24-hour races)
  • All insurance, permits, and safety staff
  • Post-race party with food and beverage
  • Official race t-shirt (for racers registered by June 15)
  • Prizes for top teams in each division as well as a gear raffle for all racers
  • USARA points for 3- and 4- person mixed gender teams​
  • 3-, 8-, or 24-hours of well-curated adventure in Western Maine!
