About the Event

The Oregon Cascades 100 returns to Sisters, Oregon on July 25th, offering runners the chance to tackle a challenging point-to-point race from Bend through picturesque mountain terrain. This event is known for its rigorous elevation changes and stunning trail views along single-track paths that wind through the heart of Central Oregon's Cascade Range.
On race morning, participants gather in Pacific Crest Middle School before setting off at dawn on an early July day with temperatures ranging between 11°C and 31°C, typical conditions for this time of year. The course begins smoothly but soon transitions into more rugged terrain as runners navigate through varied landscapes that showcase the beauty and difficulty of Oregon's trails.
Since its inception, the event has attracted approximately 200 participants annually who challenge themselves over either the full 160.9K distance or the intermediate 80.5K option. The race raises funds for local trail maintenance and conservation efforts within Deschutes National Forest, making it a key event in supporting sustainable recreational opportunities.
The Oregon Cascades 100 primarily takes place on single-track trails that weave through diverse ecosystems from lush forests to rocky outcrops. Runners face significant elevation gain early on before descending into the Sisters area via dirt and gravel roads interspersed with aid stations at regular intervals offering essential support along the way. The course profile is steep in the beginning but gradually levels off as participants approach their finish line.
Weather conditions are expected to be generally mild, though temperatures may vary widely between morning coolness and afternoon warmth, with minimal precipitation risk. Participants should prepare for moderate winds and high UV exposure throughout the day while navigating trails that remain dry despite potential heat.
