About Lake Sonoma Race Series
Come experience one of the most RELENTLESS and beautiful ultras on the West Coast, with two 'California Classic' 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 LS100K 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.

The course, while relentless, will have generous cutoffs and aid stations to allow participants to complete the race. For the past 2 editions the cutoff time for Western States qualification has been 18 hours. We are moving forward with this cutoff for Western States, but runners who simply wish to finish will have a full 20 hours. For the safety of the runners there will be a cutoff enforced at Warm Springs Aid Statopm (mile 48.1) of 9 PM. There will be a total of 5 full aid stations and 3 water stations for the 100K meaning that runners will not have to go more than 7 miles between aid at any time. The 55K will have the same time as the 100K to complete the course and has a total of 5 full aid stations and 2 water stations and starts at 6 AM.

The Lake Sonoma Race Series is legendary for its wine country hospitality, and the new race weekend will be no exception. The LS100K-55K 'California Classic' 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.
