2026 Backyard Ultra
Get ready to run until you drop, because on September 26th at Leominster State Forest we're hosting our 2nd annual Backyard Ultra!
What does that mean?
Every hour, runners must complete a 4.167 mile loop - a yard - until they can't. That's it! If you don't make it to the starting line at the turn of the hour, you're out! Once a final runner runs a yard alone, the race is complete.
Whether you want to push yourself to your limits, mingle with new runners, or just want an excuse to be in the woods for a Saturday, you'll be in the right place.
We will provide some light snacks, drinks(water, Gatorade, etc.), a porta potty, and a canopy (or two) for shade. Suggestions on what to bring include camping chairs, picnic blankets, your own food and water, a hat, first aid supplies, and a change of clothes. Additionally, you must wear blaze orange during the race, as we are in hunting season and the neighboring property is hosting a hunting event during a portion of our race.
The race begins at 10:00 AM so please arrive between 9-9:30 to allow for check-in and prep. Entry Fee: $35. If you sign up before August 31st, you'll also get a t-shirt!
