A 6.706 km loop, run every hour on the hour, until one runner remains. No finish line, no fixed distance. The last runner standing is the only finisher — everyone else records a DNF.

No. Backyard 4 is designed as a first ultra. If you can run 6.7 km in an hour, four times, you're in the game.

Six chapters: Pune, Ahmedabad, Chandigarh, Bengaluru, Hyderabad and Mumbai. Same loop distance, same rules, same clock in every city.

Through the chapter page for each city. Registration opens city by city — the community hears the dates first.

52 yards — 52 loops, 52 hours, roughly 348 km — set by Sunil Sharma at Big's Backyard Ultra in Bell Buckle, Tennessee, in October 2024 — the longest last-one-standing run by any Indian. Ashwini Ganapathi holds the women's mark at 28 yards, set at our Bengaluru chapter.

Yes. Walking is strategy, not weakness. Many strong backyard runners walk parts of every loop.
