Westmore Mountain Challenge

Westmore Mountain Challenge takes place in Charleston, Vermont, on September 26, 2026. Organized by the NorthWoods Center, the event offers two trail formats: a marathon-length run (26.2 miles) and a 20-mile option described as the trail-only portion of the course. Both take place in Vermont's Northeast Kingdom, and the name points to a mountainous day rather than a fast, flat route.

The 20-mile trail-only version suits runners who want the mountain miles without the full marathon distance, or who prefer to skip whatever non-trail sections connect the longer course. The marathon-length option is for those with a marathon or long trail race behind them who want a hard, hilly effort. Either way, prioritize climbing and descending in your training, aim for a 14- to 16-week build with weekend long runs on steep terrain, and expect to hike the steepest grades. Pack layers and a way to carry water, as mountain trail events typically have fewer aid stops than road marathons.
