Lake Sonoma, California
We are excited to announce that the Lake Sonoma 100K is a 2024 Western States 100 Mile Endurance Run Qualifier!
The Lake Sonoma 100K and 55K are back and brand new for 2023!
Come experience one of the most RELENTLESS and beautiful ultras on the West Coast, with two newly designed new courses that navigate miles upon miles of single track with majestic views of Lake Sonoma, nestled in the beauty of wine country during harvest season. The new fall date will make the LS100 perfect for runners who are looking for a late season challenge, prefer cooler weather, or want to have one last chance to snag a qualifier for the Western States Endurance Run.
The Lake Sonoma Race Series is legendary for its wine country hospitality, and the new race weekend will be no exception. The LS 100K & 55K weekend will be a lively scene for athletes, complete with on-site camping, live music and of course the best local food, wine and beer Sonoma County has to offer! As always, the Lake Sonoma Race Series is a community event, with proceeds from all races supporting the Children of Vineyard Workers Scholarship Fund.

Any athlete who has been determined to have violated anti-doping rules or policies, whether enforced by the IAAF, the World Anti-Doping Agency (WADA), U.S. Anti-Doping Agency (USADA), or any other national sports federation is ineligible for entry into the Lake Sonoma 100k or 55k.
The Lake Sonoma 100k and 55k reserves the right to conduct pre- and post-competition testing for any and all performance-enhancing drugs (PEDs) listed on the current WADA Prohibited List.
