Event overview
The 2/3 Marathon is scheduled for January 31, 2026, at McCarren Park Track in Brooklyn, NY. The race distance is about 17.5 miles, which is completed by running 70 laps around the track.
Course and format
Runners complete laps on the McCarren Park track. Each lap is counted by a dedicated lap counter - a friend or volunteer who clicks a handheld counter for every lap the runner completes. The official finish occurs when the first runner reaches 70 laps; all other runners complete the lap they are currently on and then cross the line. As a result, a runner’s final lap may vary in number from one participant to another.
Additional details
The event is hosted by a comedian and uses an unconventional race format that centers on lap counting. Registration closes on Friday, January 30, 2026, at 11:59 PM ET. Visit the organization's website for the most recent information.
