Persistence Backyard Ultra

Persistence Backyard Ultra takes place on August 1, 2026 at Eco Park, 15889 Medway Road in Arva, Ontario. The event is capped at 67 participants and there is no waitlist.

The course is an approximate 3.36 kilometre circuit that must be completed twice consecutively within each hour to form the required 6.7056 kilometre loop. Surface types include crushed stone trail, grass, and a dirt road. The venue is private and the course will not be accessible before race day.

Runners must supply their own food and drinks; there is no potable water on site though the race will offer some hydration options. Limited electricity is available and a barbecue will be provided for food preparation. Alcohol is not permitted on site.

Each participant receives a commemorative hoodie. The event is an affiliated Silver Ticket event meaning the winner receives automatic entry to the World Team Championship. Additional prizes for the winner include a Laz Jacket, a silver coin, a free entry to the next Persistence Backyard, and a CAD 250 travel assistance payment once travel proof is provided.

Crew is limited to two people per runner at the start; crew members may be switched during daylight hours. Spectators are not allowed. Medical personnel will be on site and have authority to withdraw runners for safety reasons. There will be no official timing; completion of the loop within the hour is the requirement. A portion of registration fees is donated to the Children's Health Foundation. Refunds are handled as race credit with full credit available for withdrawals by June 17, 2026 and 50 percent credit after that date. Visit the organization's website for the most recent information.
