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 1.5 miles, ride 92+ miles then run and climb your way up the tallest mountain in the Northeastern United States. Serious athletes only need apply. The 2019 event has reached its capacity (waiting list available: see link on this page) and the 2020 event will open registration on August 1, 2019.
