Skyline Wilderness Endurance Trail Run

August 8th 2026
Napa, CA
6 Hours | 12 Hours

Skyline park has 25 miles of multi-use fire road and singletrack trails of various skill levels. As a memorial to Martha Walker, the Martha Walker Native Habitat Garden in Skyline Park was created, inviting visitors to enjoy a unique presentation of flora from all over the State.

Skyline Wilderness Endurance Trail Run will go from 7:00 AM – 7:00 PM! What’s fun about this event is that you can run a lap, take a break and head out again when you are ready, as long as your race is still open. Whether you get in 1 lap or you get in 20 laps, you have finished the race!

Each loop will be 4.1+ miles long, think backyard style, just not a back yard length or rules. Each loop has approximately 815' of elevation.
This is Inside Trail Racing style, lots of elevation gain!

The last 40 minutes of your event, we will open the small loop to rack up as many loops as you can to close out your time period. The small loop is 0.34 miles. The small loop adds a mental test component, do you go for one more big loop or hang out till the small loop is open?!
