Trailway Trail Race : Lake Somerville State Park
The Trailway Trail Race takes place at Lake Somerville State Park, Birch Creek Unit, on October 10, 2026. The course uses The Trailway, a connector trail between two park units that runs along the lake shoreline and through forested tunnels. The route has a mix of exposed shoreline running and fully canopied sections, with gently rolling terrain, some hard packed rooty sections, and areas of sand or loose soil.

The event uses a lollipop style loop. Shorter courses split from the main loop at marked intersections; the marathon distance is two identical half-marathon laps, and the 50 km extends beyond the half marathon turn around. Course markings include caution tape, yellow arrows, and confidence markers so no map navigation is required.
Aid stations are placed on course and at the start finish; they provide water, ice, gels, Tailwind, soda, and sweet and salty food. The race is cupless so runners must bring a cup or bottle. Drop bags are allowed at aid stations except Wolf Pond. Chip timing uses ankle straps and mass starts are organized per distance.
A pre race tailgate is held at the race hub the evening before, with packet pickup, a cookout, a pre race briefing, and backyard games for families.
Ruck division rules require a mandatory weighed pack, specific minimum weights based on body weight, weight carried on the back, and no trekking poles. Visit the organization's website for the most recent information.
