Race Options

24‑Hour Solo

Run one 6.7 km loop every hour on the hour.
You must be in the start corral at the top of each hour to continue.
If more than one runner remains at the 24‑hour mark, you’ll run one final lap — fastest runner wins.

24‑Hour Relay (2 person)

Grab a partner and alternate loops.
Stay in as long as you can — perfect for experiencing the 24‑hour format without committing to full solo mileage.

24‑Hour Team (2 person)

Both teammates run solo loops, accumulating as many laps (called a "yard") as possible.
Your combined total loops determine your score.
If teams tie, the winner is decided by fastest combined lap times.

12-hour

Same rules and format as the 24-hour - a great way to experience this format and challenge yourself to pushing for a 50-miler.

6-hour

Same rules and format - a great way to introduce yourself to the backyard ultra.

The Course

Two distinct 6.7 km loops, alternating directions each round.
Expect roughly 150 m of elevation per loop and a mix of:
single‑track
double‑track
roots
pine‑needle paths
hard‑packed dirt
