Race format and additional information
The race follows the Backyard Ultra format. Competitors must begin the same 4.161-mile loop every hour and continue until only one runner remains to start a lap. For 2026 the organiser has removed the night loop and will use a single route around the estate. In 2025 the event sold 190 places and had a little over 200 people on the wait list. The organiser also partners with OceanBottle to remove ocean-bound plastic for each event entrant. Visit the organization's website for the most recent information.
