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