Event Details
Course Description
The race takes place on a 6.7 km loop through Brimbank Park’s mixed trail network. Runners will weave along the Maribyrnong River, pass through shaded river‑side woodlands, tackle a few gentle climbs and enjoy open grassy sections with views of the park’s wetlands. The loop is well‑marked and repeats hourly, so you can focus on pacing, hydration and mental stamina. Whether you aim for the 25 km ‘4 Yards’, the marathon‑length ‘7 Yards’, or the unlimited ‘Open’, the course offers both scenic variety and a steady challenge.
Getting There
Brimbank Park is located on Keilor Park Drive in the suburb of Keilor, Melbourne’s north‑west fringe. The venue is easily reachable by car or public transport, but specific parking locations, costs and bus or train routes are not listed in the event details. We recommend checking the official Trailsplus website or contacting the organisers (info@trailsplus.com.au, 0418 557 052) for up‑to‑date transport and parking information and to allow plenty of time for check‑in before the 7 pm start.
Weather & What to Pack
February is summer in Victoria, with daytime temperatures typically ranging from 20 °C to 30 °C and occasional humidity spikes. Expect clear skies with a chance of afternoon thunderstorms. Dress in light, breathable running gear, wear a hat and sunscreen, and carry a water bottle or use the on‑site hydration stations. Early evening temperatures can drop a few degrees, so a light jacket may be useful after the race.

Official WebsiteFrequently Asked Questions
What is the format of the Backyard Ultra?
Runners must complete a 6.7 km loop within one hour. The loop restarts on the hour, and participants who finish each hour continue. The last runner remaining is the winner – there are no second places.
Can I choose a shorter distance if I’m not ready for the unlimited ultra?
Yes. The event offers staged “Yards”: 4 Yards (≈25 km), 7 Yards (≈42 km) and 15 Yards (≈100 km). You can register for a limited stage and, if you wish, pay the additional fee on‑the‑day to continue.
What gear and supplies should I bring?
Bring a reliable running watch or timer to track the hour, comfortable trail shoes, breathable clothing, a hat, sunscreen and enough water. A light jacket for cooler evening conditions is advisable. Check the event page for any mandatory gear requirements.
When should I arrive on race day?
Check‑in and the mandatory race briefing are required before the start. While the exact arrival time isn’t specified, it’s best to get to Brimbank Park early enough to collect your bib, attend the briefing and be ready for the 7 pm start.
