The Alyeska Climbathon is a multi-lap, all day event held on the North Face Trail (NFT) at Alyeska Ski Resort. Climbers run/speed hike/walk up the approximately 2.2 mile hiking trail ascending 2,000 vertical feet from the Hotel Alyeska to the top terminal of the Alyeska aerial tram.

A lap begins at the tram base, climbs the North Face Trail and is counted at the top of the tram. Participants descend the tram and repeat over and over.

Over the course of 10 hours, climbers lap the trail as many times as physically possible. The event starts at 9am at the base of the tram and finishes at 7pm at the top of the tram. The winner of the Climbathon makes the most up the North Face Trail before 7pm. At the 2019 Climbathon, Mikey Connelly crushed the long standing vertical record by climbing 13 laps up the North Face! Mikey churned out 26,325 vertical and 28.6 miles of running. This is the equivalent of climbing Annapurna in a day! The field of 325 climbers made a combined 1,160 laps, 2,349,000 vertical and 2,552miles on the trail while raising over $90K for GYN cancer programs. Seven climbers in the field made 10 laps or more; Denali in a day!
