Girdwood Marathon

The Girdwood Marathon, held in Girdwood, Alaska, is a challenging trail race set for October 4, 2025, featuring a full marathon (26.2 miles), half marathon, juniors half marathon, and a new 5K trails race. Starting and finishing at the Alyeska Day Lodge, the courses traverse over 30 scenic trails through temperate rainforest, including the Winner Creek Trail, Iditarod Trails, Nordic 5K Loop, and various mountain and bike paths. Known for its rugged, ultra-like conditions with creek crossings and soggy terrain, the marathon has a 4.5-hour cutoff at mile 17 for safety.

Five aid stations provide snacks and water, but runners must bring their own bear spray and hydration. The event supports the Girdwood Nordic Ski Club and encourages volunteering, especially for first-timers. Dogs are not allowed. Visit the organization's website for the most recent information.
