Happy Girls Run Sisters Sisters, OR   Oct 24, 2026

Enjoy some bonding time with women of all ages and levels in the appropriately named town of Sisters, Oregon. Choose between the all-women’s trail half marathon featuring single-track in the Deschutes National Forest (on the Peterson Ridge Trail system) with some pretty stellar views or take part in the 5K and 10K road race that winds through scenic downtown Sisters. All races cross the same finish line, welcoming all to enjoy the beautiful FivePine campus under the towering Ponderosa pines.

The Happy Girls Sisters half marathoners will enjoy spectacular single track beginning and ending at FivePine Lodge (at an elevation of 3,182 feet). The course weaves through the Deschutes National Forest offering stunning views and rolling terrain amongst the Ponderosa pines. There will be some elevation change and some climbing in the beginning, so come ready for a challenge. Sections of the trail are narrow and rocky.

10K and 5K runners can expect a mix of pavement and trail on this fast and fun course that winds through downtown Sisters. The course is relatively flat, so expect fast times!

**Make sure to register early – the half marathon is limited to 500 runners and sells out every year.
