Backyard Format Rules

The Backyard format is simple: 100 miles divided into 24 hours give you 4.167 miles for a "yard" (lap). Every hour, on the hour, a new yard will start and you must finish within the hour and be back in the starting corral for the next one to stay in the run. Complete as many as you can, last runner standing wins.


Runners and crew will be able to set up a personal area with chairs, tents, etc. around the start/finish course-line area for personal aid, gear, and rest between yards (not during).

We will give a 3-minute, 2-minute, and 1-minute warning to be inside the starting corral for the next yard.

All runners are required to be in the starting corral before the top of the hour.


Failure to line up in the starting corral will result in the disqualification of the runner. Participants must start a new yard at the sound, and continue out on the course (not back to their tent, etc.).

Once you are on the course, you are not allowed any aid from your crew or any other individual. No non-competitors on the course (including eliminated runners). Except for restrooms, competitors may not leave the course until each loop is completed. Runners are responsible for their own aid on the course (carried with them). You must be on and stay on the course unless you need to use the bathroom.

No artificial aids (including trekking poles) are allowed.

Once you complete the yard, and assuming you have finished within the hour, you may use the bathroom, eat, drink, sleep, ponder the next yard, etc., but you MUST be back in the start corral at the beginning of the hour to continue into the next hour’s yard.

Runners will continue until ONE runner completes a FINAL lap. (i.e. If there are two runners left and one does not complete the loop, then the one that completed the loop will be declared the winner).

No pacers whatsoever.

You must checkout with the race director once you can not complete a yard or decide not to begin the next yard.

Live tracking will be online (stay tuned for link).

The TROT volunteers and crew will provide aid at the start/finish line. See the volunteer tab (once available) to signup to help out and earn TROT race credits and more.

TROT has reserved RV sites 14-18 for general runner tent/chair support setup (no parking, RV's, etc.) Book your own RV spot here.
