Virtual Backyard Ultra
Last runner standing, solo
Free
Run the last-one-standing format on your own. Every hour, on the hour, run a yard. Finish in time, rest, repeat. The app is your corral clock and GPS distance tracker.
Virtual Backyard Ultra turns the last-one-standing race format into something you can run solo, anywhere.
The rules are simple. Every hour, on the hour, you run a "yard" — a set loop. Finish inside the hour and you earn a rest until the next one begins. Miss the cutoff and you're out. The last runner standing wins, so the only goal is one more yard.
Virtual Backyard Ultra is your timekeeper and distance tracker for every yard:
• Corral clock — a clear countdown to the top of the hour, with audio, haptic, and spoken cues at 3-2-1 and the starting bell.
• GPS distance — track how far you cover each yard, with live distance-to-go and turnaround prompts on out-and-back courses.
• Your format — set the yard distance, interval, and course type. The classic 4.167 mi per hour (24 yards = 100 miles) is one tap away.
• Live Activity & Dynamic Island — keep the corral clock on your lock screen and in the Dynamic Island while you run.
• Apple Watch — the corral clock on your wrist: the yard you're on, the countdown to the next bell, and your distance. It taps you at the bell, when you finish, and if you miss a corral.
• Race resume — if the app goes down mid-race, from a crash or a force-quit, reopening it puts you straight back in with the clock where it should be.
• History & personal best — every run is logged, with your longest streak front and center.
• Export & share — save a finished run to Apple Health as a running workout, one segment per yard with your route, or export a .fit or .gpx file. Share a result card when you're done.
• Screen-off friendly — distance keeps counting in your pocket, and the bell still rings.
No account. No sign-up. Just you, the clock, and one more yard.
