No finish line. No set distance. No podium of three. You run a 6.7056km loop every hour, on the hour, until you're the only one left moving.
Every hour on the dot, the next loop begins. Miss the start — you're done.
Finish the 6.7056km loop and rest until the next one starts. Or pull out. Your call.
When only one runner remains willing to start the next loop — they're the winner. The rest are DNF.

Set in the heart of the Riverland, Loveday Adventure Park provides a purpose-built course environment. 6.7056km — GPS verified, reflective flagged, night-ready.
Riverland BYU runs under the official Big's Backyard Ultra rule set. No exceptions. Know them before you toe the line.
Loop or out-and-back. Must be exactly 4 miles 880 feet — 6.7056km. GPS verified before race day.
Sized to fit the entire field. The corral stays the same size throughout the race. All participants must be inside at the bell.
Each yard (loop) starts precisely one hour after the last. Warnings sound at 3, 2, and 1 minute. All competitors must start at the bell — no late starts.
No leaving the course except to use restrooms — and only after finishing the loop. No non-competitors on the course. No personal aid during a yard. Slower runners must yield and allow passes.
Each yard must be completed in under one hour. No artificial aids — including trekking poles. Miss the cutoff or miss the start — you're done.
Trekking poles and all other artificial propulsion aids are prohibited. Run it clean.
The winner is the last person to complete a yard when all others have stopped. Everyone else is officially DNF. Results are given in yards completed.
If no participant can complete one more yard than anyone else — there is no winner. The race is open-ended. It ends only when one is left standing.
The race has no set duration or distance cap. It runs until one remains. Riverland BYU starts 13 March 2027 at 12:00pm midday — and ends only when one is left.

Solo glory is the heart of backyard ultra — but at Riverland BYU, four runners can lock in together and go to war as a team. Every loop counts. Every hour counts. Last team standing.
Declared at registration. No day-of formation. You go in together.
Every loop completed within the 60-minute window adds a point to the team total.
If a runner doesn't complete yard 9, only yard 8 counts. Every completed loop stays on the board — nothing is lost, but incomplete yards don't score.
Separate award. Highest combined loop count wins.
Four go in. No swaps, no late additions. Last team standing.
