About Lake Sonoma Race Series
Come experience one of the most RELENTLESS and beautiful ultras on the West Coast, with two 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 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 approximately mile 50 of 9:00PM. There will be a total of 7 full aid stations and 4 water stations for the 100k meaning that runners will not have to go more than 8 miles between aid at any time. The 55k will have the same time as the 100k to complete their course. The 55k will have a total of 5 full aid stations and 1 water station
