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. In 2023, the Lake Sonoma added the Trail Sisters Half Marathon, shifted the event start and finish location to the Lake Sonoma Visitor Center, and added a cash prize purse for the 50 Mile event. All races are held in beautiful wine country and consist of nearly 95 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 brought a new race directing team made up of Gina Lucrezi and Justin Keller, the founders of Trail Sisters. They have integrated 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 are the event hosts, making sure the race experience is second to none! New for 2025, adidas TERREX is the official partner of the Lake Sonoma 50 Mile, Marathon, Trail Sisters Half Marathon, so expect great gear and the opportunity to demo TERREX products.
