🏔️ IROSIN CALDERA BACKYARD ULTRA MECHANICS 🏔️
Think you have what it takes to be the Last Runner Standing?
A Backyard Ultra is unlike any race you've ever experienced.
⏱️ Every hour, runners must complete a 6.706 KM loop.
🔔 When the next hour begins, everyone starts together again.
😴 Finish early? Use the remaining time to rest, eat, recover, and prepare for the next lap.
Then do it all over again.
And again.
And again.
Until only ONE runner remains.
📜 IMPORTANT RULES
✅ Be inside the starting corral before the bell rings.
✅ Stay on the official course at all times.
✅ Start every loop with all remaining competitors.
❌ No late starts.
❌ No pacers.
❌ No personal aid on course.
❌ No re-entry once eliminated.
Fail to finish a lap within the hour?
You're out.
Miss the start of the next lap?
You're out.
🏆 HOW DO YOU WIN?
The race continues until only one runner successfully completes a yard.
But there's one final challenge...
That runner must complete ONE MORE SOLO LOOP to officially become the winner of the Irosin Caldera Backyard Ultra.
🔥 One Loop.
🔥 One Hour.
🔥 One More Chance to Quit.
The only question is...
How many loops can YOU survive?
