Sydrehs Back to Frontyard Ultra
Sydrehs Back to Frontyard Ultra is a backyard ultra held at Herdsman Lake in Perth. The event runs from 22 May 2026 to 24 May 2026 and lists the venue address as 6/10 Munt Street WA 6053. It is organised by Ultra Series W.A.
Runners complete a loop of 6.71 km on the hour, every hour, continuing until only one participant remains. Any runner who times out on a loop or does not continue is recorded as a DNF. Completing 24 consecutive hourly loops of 6.71 km is equivalent to 100 miles.
The event is described as the reverse of Herdy’s, using the same location at Herdsman Lake and occurring in May, noted as a cooler time of year for the venue. AUTRA members receive a 10% discount for this event.
The format emphasises repeated hourly loops rather than a fixed distance entry. Information provided focuses on location, dates, organiser, loop distance and the last-person-standing format. Visit the organization's website for the most recent information.
