The beautiful wine country 100k consists of nearly 90 percent single-track trails weaving through relentless rolling hills, testing runners with three big climbs, and traversing more than a dozen creek crossings. Ultrarunners travel to Sonoma from over 20 countries to experience one of the globe’s most popular and distinctive ultrarunning events, one that includes a trail movie festival, gourmet athlete dinner, multiple industry panels, and a lively finish line celebration featuring award-winning wine country chefs, multiple breweries, and celebrated wine from Wilson Artisan Wineries. Participants as well as their families and friends will enjoy Lake Sonoma and Healdsburg’s small-town charm at an event where proceeds support the Children of Vineyard Workers Scholarship Fund that expands educational opportunities for local students.
