Lake Sonoma 100K, 50K, TS Half Marathon

The Trail Sisters (TS) Half Marathon is a women’s only event. It was created to foster encouragement and camaraderie amongst all abilities and experience levels. This out and back course starts with steep trail ascent to South Lake Trailhead, but also provides a speedy descent to the finish. True to its label, you can expect relentless rolling hills that will challenge your mind and body. Lucky for you though, you will share the journey with a community of supportive Trail Sisters to help you through! You will have 4 and half hours to complete the half marathon course.
