What is a backyard ultra?
One loop. Every hour. No finish line.
The format is brutally simple: a 6.7 km loop you must finish before the next full hour strikes. Then the next lap starts — again and again. There is no set distance and no finish time. The race is over once the second-to-last runner has dropped and the last runner has completed one full loop alone.
Whoever can start — and finish — one more lap when everyone else has given up is the last runner standing. Everyone else is recorded as DNF.
