About the Race

Founded in 2008, the iconic Lake Sonoma 50 Miler is a community event with proceeds supporting educational opportunities for local students through the Wilson Winery Children of Vineyard Workers Scholarship Fund. New for 2022, the LS event weekend now includes a Marathon distance for folks who prefer a shorter version of the Lake Sonoma experience.  Both races are held in beautiful wine country and consist of nearly 90 percent single-track trails weaving through relentless rolling hills. The course tests runners with various climbs, and traverses more than a dozen creek crossings. The race is well-known for having one of the most competitive fields in the United States according to UltraRunning magazine.
The 2022 edition of Lake Sonoma also brings a new race directing team, please welcome Gina Lucrezi and Justin Keller, the founders of Trail Sisters. They will be integrating their vision and focus on community with a tie to equity and approachability. Skip and Holly Brand and the amazing team at Healdsburg Running Company will be the event hosts, making sure your race experience is second to none! Additionally, The North Face has been named the official partner of the Lake Sonoma 50 Mile and Marathon, so you can expect great gear and the opportunity to demo TNF products. 
For over a decade, ultrarunners have traveled to Sonoma from over 20 countries to experience one of the globe’s most popular and distinctive ultrarunning events, one that includes a fun-run activities, gourmet athlete dinner, athlete panels, and a lively finish line celebration featuring amazing food, multiple breweries, and celebrated wine from Wilson Artisan Wineries.
