Join us in Healdsburg, California, April 11th and 12th 2025 for the the Lake Sonoma 50 Mile, Marathon, and Trail Sisters Half Marathon!

The Classic 50 Mile and Trail Sisters (TS) women’s half marathon courses are an out and back style, whereas the marathon course will make a complete loop around Lake Sonoma, crossing the iconic lake bridge. All of the courses boast of “relentless” rolling hills surrounding beautiful Lake Sonoma. Additionally, the out and back courses present an ability to connect with other runners, providing opportunity for high-fives and well wishes.

When it comes to performance, these are perfect events for speedsters looking to test their fitness, and for the first timers who are looking for a challenging, yet encouraging course. We will be providing cash awards for the top five male and female athletes in the 50 mile event!

In true trail community fashion, all three race events start and finish at the Lake Sonoma Visitor Center green space. This festival-like atmosphere is designed for celebration and for fostering community.

Speaking of celebrating, we will have a full schedule of pre and post-race events, including athlete panels, community dinner, socials, and of course wine tastings. You can’t come to Lake Sonoma and not try the wine!

We hope you will join us for the 50 Mile, Marathon, and TS Half Marathon, April 11th and 12th 2025! We look forward to celebrating with you at that finish line!
