The record so far
Sam Harvey is a New Zealand endurance athlete and coach whose best-known results connect the backyard and mountain-trail worlds. At Dead Cow Gully in 2025 he completed 118 yards for 791.308 km, setting the New Zealand national record while assisting Phil Gore’s 119-yard world-record win.
The result extended a partnership that had already reshaped the format in 2023, when Harvey reached 101 yards and Gore completed a record 102nd. Harvey also placed ninth at Big’s that year with 91 yards.
Away from the hourly format, Harvey won the Kosci Miler at Ultra-Trail Kosciuszko by UTMB in November 2024 and the 2025 Tarawera Ultra-Trail by UTMB 100-mile race in 15:16:54. The victories add front-of-field trail results to his backyard record.
Harvey heads New Zealand’s official selection list for the 2026 Backyard Ultra World Team Championship, which starts on 17 October 2026. He won the New Zealand site of the 2024 edition with 73 yards, which Backyard Ultra NZ still lists as the New Zealand venue record.
