BALS Backyard

The BALS Backyard is a "Last Person Standing" style event held at Westminster Park in Rock Hill, South Carolina. Participants traverse a 4.167 mile loop on the hour, every hour, until only one runner remains. The course utilizes the park's trail system and features approximately 400 feet of elevation gain and loss per loop. The same route is used for both daytime and nighttime loops.

The rules follow the traditional backyard ultra format. Three minutes before the start of each hour, three whistles are blown, followed by two whistles at two minutes, and one whistle at one minute. A bell signifies the start of the loop. Runners must be inside the start corral when the bell rings to continue. No aid can be received from crews while a runner is on the course; aid is only permitted once a runner returns to the corral. To be declared the winner, the final participant must complete one additional solo loop.

The event facilities at Westminster Park include:

  • A pavilion to protect runners from the elements.
  • Permanent restroom facilities.
  • Ample space for 12x12 foot crew camps in an open field.
  • A playground and 18-hole disc golf course.

An aid station is provided at the pavilion, offering water, electrolytes, and minimal organic snacks such as fruit sauce pouches and handmade treats. Participants are responsible for their own primary fueling strategy. Those who complete 8 loops (50K) receive a commemorative pin, and the final winner receives a custom painting.
