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 2nd edition of the Persistence Backyard Ultra, beginning on August 5th, 2023.

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.

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 2023!

Registration will open in October of 2022.  To check out the details from last year’s first edition of the race, look here.

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