About
The race
Project 13.1 is a specialized, high-performance half marathon held at Rockland Lake State Park in Congers, New York. Designed primarily for competitive athletes and serious recreational runners aiming for personal bests or aggressive time goals (such as Olympic Trials Qualifiers), this no-frills event prioritizes speed over spectacle. The USATF-certified course features an incredibly flat, fast route running clockwise around the lake. Offering professional-style race amenities like elite-level pacers and personalized bottle service stations, it has earned a strong reputation as one of the premier destinations in the country for runners looking to chase a blazing-fast half marathon time.

Loop Around the Lake
The course is a loop around Rockland Lake, so you'll return to the start area; plan your bottle access and pacing accordingly. Use the lap to run even splits.

Personalized bottle service stations let you run with your own nutrition; label your bottles and note where stations are on the loop so you don't miss them.

Drive to the Park
Rockland County is car-oriented; public transit won't get you close to Rockland Lake State Park. Plan to drive and arrive early to avoid entrance congestion.
Spectator Viewing
Spectators can watch from the lake path inside Rockland Lake State Park, seeing runners multiple times on the loop. The flat course keeps sightlines open.
Nyack Recovery
After the race, Nyack's walkable downtown and Hudson River waterfront are a good spot for a recovery stroll. The area's suburban-river mix is its character.
