Project 13.1

America's Fastest Half! Registration for the fastest half in the country is officially live on October 1, 2025! Grab your spot, because the race will be limited to the first 500 who register and we expect the event to fill up fast.  The race will take place on Saturday, March 21, 2026 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! All registered runners will get a 2026 Project 13.1 hat from Fractel as well as a full catered breakfast with muffins, fruit, eggs, waffles, and more. Visit our website to learn more.
