About
Red’s Backyard Ultra is a backyard ultra set on a NSW State Cross Country course in Kembla Grange, roughly 1.5 hours south of Sydney. It is a last-one-standing event where runners complete a 6.706 km loop every hour on the hour until only one remains. Founded by Red Barnett, the event has grown into a community-driven ultra with a mix of competition, camaraderie and iconic themed loops.

FAQ
What is the course like?
The course consists of two sections on a NSW state cross-country course: the first section runs clockwise (red), the second anticlockwise (blue). It is relatively flat, non-technical with manicured grass and trail, marked with red and white peg flags, signs, bunting and reflective markers for night.
What are the entry fees?
First release: $230 until 30 April 2026. Second release: $240 until 17 July 2026. All entries include booking and credit card fees.
Are transfers allowed?
No transfers are offered. Red’s Backyard Ultra is a small event with a waitlist; if a spot opens, runners on the waitlist are contacted in order.
What happens if I can’t finish a lap?
If you don’t complete a lap before the next hour starts, you’re out (DNF). The race continues until only one runner remains — the Last Person Standing.
