Project 13.1

Lace up for speed at Project 13.1, known as "America's Fastest Half," set to take place on Saturday, March 21, 2026, in Congers, NY. This premier 13.1-mile race at the world-famous Rockland Lake State Park is engineered for personal bests, boasting a USATF/IAAF-certified course renowned for its exceptionally flat profile and minimal elevation gain. Designed as a focused time-trial experience, Project 13.1 features two distinct waves of runners, complete with dedicated pacers and individualized bottle service to optimize your race day performance. With typical race day conditions seeing highs around 49F and lows around 32F, and only an 11% chance of precipitation, the stage is set for an ideal running environment.

The course itself is meticulously crafted for speed, beginning with a 0.75-mile out-and-back segment before runners embark on four clockwise loops around the scenic Rockland Lake. To ensure every participant can run the most efficient line, tangent markers will be strategically placed along the 2.94-mile bike path that circles the lake. This "low-frills" event eliminates common race day distractions like large crowds and long lines, allowing you to concentrate solely on achieving your fastest possible time. Past runners have consistently praised Project 13.1 for its streamlined logistics, including convenient race-day bib pickup and readily accessible porta-potties, contributing to numerous personal records.

Project 13.1 has garnered a reputation as the go-to destination for runners chasing fast half marathon times, with hundreds of athletes having achieved PRs here. Upon crossing the finish line, celebrate your accomplishment with a stylish 2026 Project 13.1 hat from Fractel and a well-deserved catered breakfast featuring muffins, fruit, eggs, and waffles. The race starts near Parking Lot 5 at Rockland Lake State Park, with additional parking available in Parking Field 4, a short walk from the starting line.
