Oregon Cascades 100
Welcome to Oregon Cascades! These point-to-point courses will take you from Bend to Sisters - two of Oregon's premier running towns - where the trails (and beer) are the best anywhere!
The 100 mile race has roughly 10,700 ft of gain and 11,200ft 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 84% single-track trails and 13 full aid stations with awesome single track trails and views. You will have 32 hours, 1 minute and 18 seconds to finish. The 100 mile race is a Western States qualifier!
The 50 mile course has 4000ft of gain and 6500ft of loss with 5 aid stations and consisting of 85% single track trails and 15% gravel road, will make for fast times! The views will have you wanting to come back for more. You will have 16 hours to finish.
