Napa Lapa

The Napa Lapa Trail Adventure is Inside Trail’s first time-based run. This means that instead of running a pre-determined distance as fast as possible, you’ll be running for a pre-determined amount of time as far as possible. And what other place could be better than the beautiful, rolling hills of Napa’s Skyline Wilderness Park?

Skyline Wilderness Park is located in Napa, California. In 1979, the land beside the State Hospital was declared to be surplus and was to be sold to a private party. A group of concerned citizens got together and enlisted the help of various members of the community and government to allow the group to use the land as a park for the Napa Valley. The idea of a park was formed, a constitution was created, incorporation papers drafted, environmental impact studies made, etc. Since there has never been a private sector leasing state land for a park system, the State leased the land to the County of Napa which then subleased it to the Skyline Park Citizens Association. More on the history of Skyline Wilderness Park here.

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.

The Napa Lapa Trail Adventure 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 20 laps, you have finished the race, you are now a Napa Lapper!

Each loop will be 4.16 miles long. Test yourself and see how fast and how many you can complete. Each loop has approximately 815′ of elevation. For reference, 1 lap per hour is 14:25 min per mile; 2 laps per hour is 7:13 min per mile

This is Inside Trail Racing style, lots of elevation gain!

Plenty of Awards to go around:

The Lapa Lapper – Overall Winners

The Grappa Lapper – Fastest Lap

The Dapper Lapper – Best Dressed
