Legend has it that this race started when two sourdoughs argued whether or not someone could run up and down the mountain looming over Seward in under an hour. At the time, it couldn’t be done: the fastest time of the first organized race in 1915 was 1:02. This one-of-kind race happens every 4th of July and attracts people from all over the world to the self-proclaimed “toughest 5k on the planet” to scramble up and down 3.1 steep and technical miles with almost 3,000 feet of elevation gain. Registration is capped for this popular event – first timers have to register for the lottery for a chance to race. Even if you can’t race, this event is fun for all, with spectators flooding the streets of downtown Seward to cheer on the runners! Today, top racers make it up and down in just over 40 minutes.

Cirque Series, Girdwood
This race will test not only your grit, but also your quads. People from all over the globe travel to participate in this technical race where running up and down Mt. Alyeska means that mud, snow, rock scrambling, and often rain are all part of the course.

Views of the Chugach mountains, glaciers, and Turnagain Arm are just one of the reasons the race is well worth the climb.
