Join the Lake Sonoma 50 Mile, Marathon, and Trail Sisters Half Marathon and get the chance to win the cash prize purse for the legendary 50 Mile and Marathon. Business in the front with a party in the back! We are excited to offer Lake Sonoma’s first Party Pace pacer crew! Party pacers will aim for a 13-hour finish, leaving a one-hour grace period before the official race cutoff. Lake Sonoma isn’t just a race event; it’s a celebration. Complete the weekend with a Celebration and Thank You event at Coyote Sonoma in Healdsburg, CA. Everyone involved with the event is invited to enjoy wine, charcuterie, and share stories from the weekend.
