Alaskaman Extreme Triathlon

With a total gain of 10,100′ between the bike and run courses and an average water temp of 53°F, Alaskaman is one of the most challenging extreme triathlons on Earth.

Alaskaman is the hardest long distance 1-day triathlon event in North America. This unforgettable event will take athletes through the frigid waters of Resurrection Bay (Seward), up the winding, mountains passages of the Seward Highway, and to the top of Mount Alyeska to finish a journey that you change you as an athlete. This does not come without risk.

Having your own support IS ABSOLUTELY MANDATORY FOR EVERYONE as your support crew is your lifeline during this event. The only way it is permittable for two athletes to share a support crew is if they complete the event together and are the same speed throughout the entire event, agreeing on this ahead of time and getting special permission from the event management.

2020 will mark the 4th anniversary of the Alaskaman Extreme Triathlon. In an effort to give as many athletes a “Taste of Alaskaman” as possible, we are opening up separate categories to our registration. This will not effect the main event. Those racing the entire extreme distance will still be the only ones eligible for the covenanted finisher’s shirt and ulu knife (back as a included finisher’s item in 2020), but allowing others to participate in events like the full relay, swim, aqua bike, duathlon, and 10-mile runs, really opens the event for growth and local support on a level we haven’t seen in past years. As always the main goal of our event(s) lies with the athlete and support experience, the camaraderie, and the purity of the sport. We love Alaska and we know anyone coming here to race will fall in love with the Last Frontier as well.
