America’s Fastest Half Returns March 2027
The next installment of Project 13.1 will take place on Saturday, March 20, 2027 on the world-famous Rockland Lake State Park half marathon course, which has become the go-to destination for runners looking to chase fast half marathon times. The event will feature two waves, pacers, individualized bottle service, and controlled conditions designed to help you race under the best conditions possible. Hundreds of runners have PR'd at this event -- now it's your turn!
Registration Opens September 3. Lots more to come soon!
Additional Information
Is there a time standard to enter this event?
Kinda! Project 13.1 is built for runners aiming to complete a half marathon in under 90 minutes. We’ll have pacers to support runners going for times under that goal, and if you anticipate running a slower time, be aware that you might find yourself running solo—and other races may offer a better experience for you this spring. That said, if you’re up for the challenge and excited about what this race represents, we’d be happy to have you!
I am interested in pacing? How do I signup?
This event relies on incredible pacers! If you're interested in pacing one of the groups listed above, let us know by filling out this form. Pacing this event is a great way to log a hard workout, and you’re welcome to pace the first half and then finish the race. Pacers receive free entry to a future Trials of Miles event of their choice, event swag, and breakfast after the event. Questions? Email joe@trialsofmilesracing.com.
Is there a capacity limit on this event?
Yes. Like we did last year we anticipate having two races each with around 250-300 participants.
WHere should I stay?
Coming soon!
The Course
The Project 13.1 course, renowned as one of the fastest in the country, is a USATF/IAAF-certified route designed for speed. Runners will head out for roughly 3/4 mile, make a 180-degree turn, pass the start line, and then complete four clockwise loops around the lake. To ensure everyone follows the shortest possible path, we'll have someone marking the tangents along the course, giving you the most efficient line for every loop.
