The Experience
Happy Girls Sisters is an all-women’s trail half marathon that sells out its 500-runner cap every year. Set in Sisters, Oregon, the race draws ~205 finishers from about a dozen states, with around 11% returning year after year. The course runs on single-track in the Deschutes National Forest’s Peterson Ridge Trail system, offering stellar views and a forested, shaded route.
The race atmosphere is intimate and supportive, with a focus on women of all ages and levels. While the half is trail, there’s also a 5K and 10K road race winding through downtown Sisters for those preferring pavement. All races converge at the same finish line on the beautiful FivePine campus, shaded by towering Ponderosa pines.
Post-race, runners can enjoy the festive campus setting, which adds to the sense of community. With a median winning time around 1:32, the field is competitive but welcoming to first-timers. The limited size and growing demand make early registration essential.
