Persistence is defined as firm or obstinate continuance in a course of action in spite of difficulty or opposition.

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 3rd edition of the Persistence Backyard Ultra, beginning on August 3rd, 2024.

As a bonus for our Ontario runners, the ultra will be taking place on the August long weekend, giving you an extra day to run, or recover, without having to worry about work.  This will lead to less of those awkward “why are you walking like that?” conversations when you return to work.

Persistence will take place in London, Ontario, Canada, consistently voted the second best London in the world, since 1855.  For the geographically challenged, London is pretty much halfway between Detroit and Toronto (a two hour drive from each), and a 2.5 hour drive from Buffalo.  Then again, if you are geographically challenged, I guess that won’t help you much either.

We are very excited to welcome you to London, and the Persistence family in 2024!

Registration opens on October 28th, 2023.  For complete details about the race and/or to register, click here.

Our race is suitable for everyone ranging from the first-time backyarder to those seeking glory at Big’s Backyard.  Our first two editions saw people reach new personal bests ranging from first marathons, to first ultras, and first 100 kilometre runs.  Our 2022 winner, Amanda Nelson, and our assist, Brian Bondy, both went on to represent Canada at the Backyard Ultra World Team Championships.  The 2024 event is once again a Canadian silver ticket event.

After her second consecutive win in 2023, Amanda Nelson stated that “a national record could be set on this course.”

The Masters has the green jacket.  The Persistence Backyard Ultra has the prestigious “Laz Jacket.”  Will you claim it?
