3 triathlon events in South Berwick, Maine

The Sea to Summit is not your traditional multisport race. This is an amazing day which combines the core elements of triathlon with the challenges of an adventure race. With assistance from your support designate, or porter, you’ll swim 1.2 miles, ride 95 miles then run and climb your way up the tallest mountain in the Northeastern United States. Serious athletes only need apply.
