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.
