We know you have many options where and when to spend your hard-earned money on ultra races so we thank you for choosing the Lake Sonoma Race Series 100-55K a charity race benefitting Children of Vineyard Workers Scholarship Fund.

We are excited to offer a fall version which we call “The Western Show” featuring the 100K – a Western States Qualifier and the 55K designed to be your first ultra.
The 55K will have long cut-off times – the same as the 100K and set up with eight aid stations to ensure this loop is fun, challenging yet achievable for most runners.

At "The Lake" we intend to have a very fun “Western Show” which includes free car camping down at the start/finish. We’re excited to have a western themed environment with good food, good music, good friends, good beer, wine, whiskey and swag!

The 100K will have a finisher vest and the 100-55K will both have newly designed running hats and special gifts for the prize winners – so expect the best and thank you for joining us! – Skip
