Welcome...

The Hellathon Backyard Ultra, where the trail doesn't care how tough you think you are.

There is no finish line waiting for you. There is no easy way out. You run until your body says stop, your mind says stop, and everyone around you has already stopped. Then you run another loop.

Every hour, the clock resets. Every hour, the trail feels harder. You don't have to be the fastest; you just have to be the last one standing.

One winner.
Everyone else loses.

$15,000 CASH PURSE

$10,000 to 1st place
$4,500 to the assist (2nd place)
$500 prize for fast lap --any lap/loop of the race counts
Will you pay the ultimate price? Or will it pay you?

Aid Station

This will NOT be our typical Aid Station fare. We will provide water and Gatorade to participants.

Runners are expected to provide their own nutrition throughout the event. Having a crew is HIGHLY recommended.

We will have an area for participants to set up tents near the starting corral.

Awards/ Swag

The winner will receive a $15,000 cash prize. This will be awarded to the race participant (male OR female) who completes the last yard by themself. He or she must complete the last yard within the hour, per race rules. If no one completes this, there will be no winner.

There are no podium awards.
Runners receive nothing but the chance to be the last one standing and win the prize money.

We have swag for sale.
