Sisters, OR

Welcome to Oregon Cascades 100! This point-to-point 100 mile trail race, starting in Oregon's premier running town of Bend and finishing in the idyllic mountain town of Sisters, is an instant classic. The race has roughly 10,700 ft of gain and 11,200 of loss. Don't let the elevation gain fool you...it's packed into the first 100K of the course making this easy-on-paper race much harder than expected! The Bend side offers smooth, flowing single track in the shadow of Mount Bachelor before dropping onto some rugged terrain as you begin your descent into Sisters Country. The course consists of 90% single-track trails and 13 full aid stations. You will have 32 hours, 1 minute and 18 seconds to finish with awesome single-track trails and views. 
The race is a Western States 100 qualifying race! 

Those that finish within the allotted time, will receive a sweet custom buckle.

New for 2024!! We have added a 50 mile option to this stunning course! The 50M will start at Swampy Lakes Sno Park. Runners will be shuttled from the finish area at Sisters Middle School to the start. 

This is a classic point-to-point 50 mile race with incredible views and great single track trails to make the miles tick by.
