Inspired by the preeminent, international swimrun race series ÖTILLÖ (island to island), originating in Sweden in 2006, two multisport veterans looking for the next adventure are pleased to once again present in 2017 the ONLY “ÖTILLÖ-style” swimrun event in North America.

Consisting of multiple, alternating swim and overland running legs (island roads, trails, and shoreline scrambles) between several islands in Portland, Maine’s spectacular Casco Bay, the race will test competitors with run legs across varied island terrain and several miles of open water swimming. For 2017, a Long Course event is in the works for approximately 5 miles of open water swimming and nearly 16 miles of overland routing over 12 islands. A simultaneous Short Course event for newcomers will consist of approximately 2 miles of swimming and 6.5 miles of overland racing over 4 islands.

Remaining true to the originators of the ÖTILLÖ, Casco Bay Islands Swimrun is a two-person team event. Not a relay, teamates must race the entire course together. Rules permit swim aids such as hand paddles, pull buoys, wetsuits and even swim fins to name a few. Certain safety gear is mandated by race rules and hydration and race fuel can be carried too, but what one starts with, so too must they finish. Changing from trail shoes to swim fins, or tending to awkward gear can chew up valuable time. Having the right teammate and equipment can make all the difference
