Grills Trail Run 2026

Grills Trail Run is a fall trail race at Grills Preserve in Westerly, Rhode Island, offering 10-mile and 10-km options. Both races begin and end within the preserve, sharing the initial mile before diverging. This design provides a focused local trail event, distinct from road races merely labeled as trails. Westerly Track & Athletic Club organizes it as part of its fall race series. The event is intentionally straightforward, featuring club timing, no race shirts, and a lower entry fee compared to larger races. The course consists mainly of single-track trails, approximately 80 percent narrow and 20 percent double-track, incorporating riverfront sections and bridge crossings. The 10-mile route extends from Grills Preserve into Grills Wildlife Sanctuary in Hopkinton. Walkers are directed to the 10-km option, as the longer race has a 2 hour 30 minute cutoff. Strollers and dogs are prohibited, aligning with the course's tight trail format. The race contributes to the WTAC Fall Race Series standings, with a discount available for participants registering for multiple series races.
