About Lake Sonoma Race Series
Founded in 2008, the iconic Lake Sonoma 50 Miler is known for having one of most competitive fields in the United States according to UltraRunning magazine. 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.
