KENT
BACKYARD
ULTRA
Trend-setters. Cool kids. Mavericks.
You’re not here for ordinary. You’re here for something that means something.
At a Backyard Ultra, the start line comes every hour.
The finish line? That’s up to you.
4.167 miles. On the hour. Every hour.
No set distance. Just your own goal and the people pushing with you.
4 unique challenges. 1 fantastic county.
However you show up, there’s a place for you here.
SERIES PASS
Four events. One wild ride.
This is for the ones who aren’t here to play it safe.
You want meaning, challenge, and stories worth telling.
The Kent Backyard Ultra Series Pass gets you into all four events. No panic about sell-outs, no FOMO, just your name down for every round.
Every start line is a fresh shot at going further.
Every finish brings you closer to the coveted Black Series Buckle, a reward only a few will earn, and even fewer will forget.
Go for distance, build your streak, or just show up and surprise yourself.
Whatever your reason, this is the pass that gets you in every time.
Snag your Series Pass. Four races. One adventure you won’t regret.
LAST ONE STANDING
One event. As many yards as you can handle.
Not ready for the full series? No problem.
With Last Person Standing, you can enter any of our four fantastic Backyard Ultras as an individual challenge.
Each race sticks to the classic format:
4.167 miles, one yard, every hour on the hour.
You keep going until you can’t.
Choose the event that suits you, the location, the vibe, the timing.
Show up, line up and see how far you can go, one yard at a time.
And yes, even in a single event, go far enough and you’re in the running for the Black Series Buckle.
Pick your race. Push your limits. One more yard.
7-HR CHALLENGE
Seven hours. Seven yards. Everyone DNFs.
Think you’ve got seven in you?
This one’s short, sharp and surprisingly fun.
The 7-Hour Challenge sticks to the classic Backyard Ultra format:
One 4.167-mile yard, every hour on the hour.
Seven rounds. No more. No less.
Miss a start and you’re out.
Make it to the end and you’ve still DNF’d just like everyone else.
But you’ll finish with 29.17 miles and a whole new level of respect for the format.
It’s the perfect way to get a taste of the format, whether you’re aiming to go fast, pace smart, or just enjoy the ride with friends.
Pick your venue. Run the 7. Finish with a grin.
