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 Sea to Summit Triathlon is a largely self-supported race consisting of:

• a 1.5 mile swim in a tidal river connected to the Atlantic Ocean
• a 91-95 mile bike ride (depending on course variations) from Maine into New Hampshire, following roads of your choosing, with 6000 feet of climbing
• a strenuous five mile run/climb up the tallest mountain in the Northeast: Mount Washington, with 4300 feet of vertical gain in altitude
