2026 Date - December 12th
Long Island has a rich and deep running culture. There are multiple events every weekend to choose from. However, runners that enjoy longer race distances or trail events have only a few options to choose from over the course of the entire year. This event will provide an opportunity for those that enjoy ultra or trail running to participate in a unique event. A portion of the proceeds will benefit the Long Island Greenbelt Trail Conference, who help maintain the trails on Long Island.
A backyard ultra is not a race to see who is the fastest but see who can endure the longest. Participants will run 4.167 miles every hour on the hour, but will be required to drop out if they cannot complete the distance in that time period. The final competitor to be able to complete a full loop will be declared the winner.

From Endurance Grid
This race spans more than one sport — here’s a guide to each, so you can understand what’s involved and decide if it’s the right fit. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
Running off-road — dirt, singletrack, and mountain paths — from 5Ks to ultras. The terrain, not the pace, is the whole point.
