New Additions for 2025!
Join us in Healdsburg, California, on April 12th 2025 for the TERREX Lake Sonoma 50 Mile, Marathon, and Trail Sisters Half Marathon! We are excited to announce adidas TERREX as our presenting partner!
We are stoked to team up with Mountain Outpost to bring you full livestream coverage, athlete panels, interviews, and commentary from special guests!
Leaning into our competitive heritage, we will provide a cash prize purse for the legendary 50 Mile and Marathon. We will celebrate the elite field with a separate elite men’s and elite women’s start!
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. We always 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.
See you on that start line!
