A Backyard Ultra running Event. Runners complete a 6.71km loop hourly. A cattle bell signals the start of each new loop, with whistle warnings at 3, 2, and 1 minute beforehand. All participants must begin the loop precisely on the bell; no late starts are permitted. Runners are eliminated if they:

Fail to complete a loop and return to the corral within the hour.
Are not in the starting corral when the whistle blows for the next loop.
Voluntarily decide to stop mid-loop and do not continue.

The race continues until only two runners remain. The "Assist" is the second-to-last person to drop out, while the Last One Standing, or winner, is the final person to successfully complete a loop within the hour. If no runner can complete an additional loop within the time limit, there is no declared winner. All other participants are marked as "DNF" (Did Not Finish).
