Why you dream of this race

THE DREAM

ABOUT THE RACE

A day you'll remember,
long past the finish line.

The course starts at Skyline Wilderness Park, crosses the rolling terrain of Napa Open Space, and enters the newly opened Suscol Headwaters Trail.

Few runners have explored these trails yet.

The route features continuous climbs, oak-covered ridgelines, and distant views down the Napa Valley.

The course consists of two and a half large loops.

Each full loop is approximately 22 miles, while the final loop is replaced by a shorter 10K section,

reducing the elevation burden somewhat in the latter stages.

The course climbs and descends along oak-covered ridges, with views across Napa Valley.

According to information for the nearby Napa Wilderness Trail Run,

the higher sections offer views of Mount Diablo to the east, Mount Tamalpais to the west, and Mount Saint Helena to the north.

The Suscol Headwaters section is relatively little known because it opened only recently.

Typical race-season temperature: around 16°C (60°F): Short sleeves or light long sleeves + arm warmers
Aid stations: 4
