Summit Trail Racing Event

Saturday | November 19th 2022 | 8am – Last Person Standing

What | The Purpose

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! For every competition, loops completed count towards an at-large bid for Big Dogs World Championship in October 2023!


  • 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. There is plenty of room to set up for your racer. Tents and 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.
