Persistence Backyard Ultra

Persistence Backyard Ultra is an official affiliated race of Big Dog's Backyard Ultra. The event will run as its fifth edition beginning on August 1, 2026, and is presented as Ontario's original affiliated backyard.

The race is described as open to all runners, from those who might run one loop to those who might run many. The organisers include a definition of "persistence" as firm or obstinate continuance in a course of action despite difficulty or opposition, reflecting the event's theme.

The event takes place in London, Ontario, Canada. London is noted as being about a two hour drive from Detroit and from Toronto, and roughly a 2.5 hour drive from Buffalo. The race is scheduled over the August long weekend, providing an extra day for running or recovery without work constraints.

Recent "Last One Standing" results by loop count:

2022: 33 loops
2023: 32 loops
2024: 47 loops
2025: 43 loops

Assist roles were recorded in past editions. Further information about the Backyard Ultra format is provided by the organisers. Visit the organization's website for the most recent information.
