The 2016 SwimRun USA Casco Bay Islands

The first island to island style SwimRun race hit US-soil on Sunday in Maine’s Casco Bay Islands off the seaport city of Portland. 121 two-person teams started out over the 4-miles of swimming and 10-miles of running over seven different islands and all but four teams completed the course.

Dan Kimball and Marcus Barton are a very experienced and accomplished team, and they were in a tight race for the men’s podium throughout the day.

Earlier that day, following a half hour delay due to heavy fog the race got underway on Chebeague Island with a 1.8-mile run.

Matthew Hurley and John Stevens from Portland, Maine, arrived on the rockiest section of the course at Vaill Island with sizeable lead on the other teams.

The second team to come ashore on Vaill Island was the mixed team of pro triathlete David Thompson and Bridget McCoy from Minnesota.
