The Details!

Summit Trail Racing is excited to host the Backyard Ultra - Last Person Standing trail race to kick off the Thanksgiving holiday. From the brain of Lazarus Lake, participants will run a 4.1667 mile loop every hour till there is only one person standing. Run it fast, run it slow, run it how you want. You just have to be back in the starting area before the next loop starts! This is an officially sanctioned Backyard Ultra. The number of loops you complete will count towards an at-large bid for Big Dogs Backyard Ultra World Championship 2022! Runners get our signature Seeking Summit Boco Performance Trail Hat along with other fun race swag! The winner gets the Summit Cowbell Trophy and $100 cash!


Be back to the start line in 60 minutes (minimum 14:23 min/mile pace).

We will give you a 2 minute and 1 minute warning to get lined up for the next loop.

Crew access is available at the start/finish. We will provide Cold Water, Tailwind and lots of race snacks to keep you going throughout the day! There is plenty of room to set up for your racer. Tents are allowed.

No pacers whatsoever.

We will provide aid at the start/finish (water, ice, and orange-flavored-Tailwind, race snacks).

To win, you must be the only person left standing, the last runner.
