Wild Goose Trail Festival

Wild Goose Trail Festival runs in West Milford, New Jersey, on September 19–20, 2026. Organized by Sassquad Trail Running, the weekend lines up seven trail formats: a 100-mile, a 100K (62 miles), a 50-mile, and a 36-hour timed event on Saturday, September 19, followed by a 50K (31 miles), a half marathon (13.1 miles), and a 10K on Sunday, September 20. Whatever distance you choose, you will be racing on trails in northern New Jersey.

Festival formats like this let a household or running group pick different distances on different days, from a first 10K trail race to a full ultra. The 36-hour event and the 100-miler are for experienced runners who have already completed a 50-mile or 100K and can manage overnight running. Runners targeting the 50K or half should focus on a 12- to 16-week block with weekly time on rolling trails, hill repeats, and one long run that gradually approaches race duration. Multi-day options also make it possible to volunteer or crew one day and race the next.
