Maribyrnong Valley Park Backyard Ultra - MVP Backyard Ultra
The event takes place from Fri 5th Feb to Mon 8th Feb 2027 at Brimbank Park, Keilor VIC. It uses the backyard ultra format: runners complete a 6.7 km loop every hour, and must finish each lap within the hour to continue. After each hour, all participants who have completed that lap are considered tied for first place; the event continues until only one runner remains.
Entry options include staged distances and an open option for unlimited laps. The listed stages are:
- 4 Yards (25 km)
- 7 Yds (42 km / marathon)
- 15 Yds (100 km)
- Open (unlimited laps)
Fees are published for previous years with tiered pricing (super special, early, standard, late) and include GST; ticketing fees are added at checkout. Trailsplus donates $1 per participant to Canteen, an Australian organisation for young people living with cancer; in 2025 the event had 180 competitors and contributed to Canteen donations. Course maps and an event guide PDF are provided by the organiser. The format emphasises time management and endurance rather than speed.
