If you’re a seasoned trail runner, this race has the vibe you love! If this is your first trail race, this race has the vibe you’ll soon love! We are excited to show you the beautiful trails that 525-acre Walnut Creek Park has to offer. As a bonus, it's held on the beautiful and iconic TJ100k course- come cut your trail teeth in the footsteps of legends!

The race is approximately 90% wooded single track/double track and 10% open cross country/jeep road and features spectacular views of the 45 acre lake on site. Course links below!

Note for the Winter Series!

Also new for this year! We're providing a coordinated effort between the three Winter Series events, Burke Creek Barn Burner, Walnut Creek 5 and Dime, and Naked Creek 10k/25k. Participants in each event will receive a commemorative prize at the completion of the series, at no additional cost, regardless of the distance completed!

You can run any combination of the race distances across the three events, but will need to register for each event separately, and we're going to do our best to keep track of everyone participating.

Please note there are no refunds and the event will take place rain or shine. Inclement weather affecting the safety of participants or causing adverse trail impacts may cause delay or rescheduling of race.

THE DIME ROUTE: 1350 feet of elevation gain

THE NICKEL ROUTE : 446 feet of elevation gain over a 5k+ ;)
