We are so incredibly excited and honoured to welcome you to our signature event, the Persistence Backyard Ultra, Ontario’s original affiliated backyard ultra.

Do you have enough persistence to push yourself further than you think is possible? Do you have enough persistence to be the Last One Standing? Find out during the 5th edition of the Persistence Backyard Ultra, beginning on August 1st, 2026.

As a bonus for any Ontario runners, the backyard will be taking place on the August long weekend, giving you an extra day to run, or recover. That will lead to less of those “why are you walking like that?” conversations when you go back to work.

The Backyard is for all runners. Past years have seen a number of runners reach new personal bests, completing their first marathon, ultramarathon, or going further than they ever had. How far can you go?

This year’s event is once again a Silver Ticket event. This means that our winner receives an automatic entry to compete in the World Team Championship!

We are very proud that the 2022, and 2024 events sent two runners, our winners, Amanda Nelson and Justin Wright, and our assists, Brian Bondy and Francois Decelles, to the World Team Championship.

The Persistence Backyard Ultra is an official affiliated race of Lazarus Lake’s Big Dog’s Backyard Ultra.

As with all of our events, a portion of each registration will be donated to the Children’s Health Foundation in support of children and their families in our community.
