Inspired by the preeminent, international swimrun race series OTILLO ("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 "OTILLO- 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, SwimRun will test competitors with run legs across varied island 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 15 miles of overland routing over 10 islands. A simultaneous Short Course event for newcomers will consist of approximately 2.25 miles of swimming and 6.5 miles of overland racing over 4 islands.
