Summary: One of the more scenic 100 milers in a remote area in Central Oregon, this race is mainly an out and back course with a 26 mile loop at the start and a 15 mile loop at the furthest point out. Along with featuring 60 miles of the Pacific Crest Trail, the course is a mix of singletrack (87.7 miles), jeep roads (12 miles) and pavement (.2 miles), along with a gain of ~10,800 feet. 2017 was a different course due to wildfires, so the gain was ~2,000 feet more, and at least 8 inches of recent snow made for a very challenging race.

Lessons Learned from Race Reports

All aid stations are cupless
Unlikely to have cell service at the race, so if you are meeting people or pacers and/or crew are coming, have a plan for meeting without needing cell service
The area in general has not much more than campsites, so come with all the supplies you need, plenty of gas and food, and give yourself enough time to drive there with really slow, pot-holed roads
First loop has some of the more technical trails
PCT miles are traditionally more runnable, but don’t expect them to be non-technical
Have warm layers for when the sun goes down, as it will be chilly at night
Roads for crew are fairly rough and tough to navigate, especially at night. Make sure your crew knows this going in.
Course is very well marked
Rocks are slick in the morning at the start and the next morning from morning dew or if it’s rained – be careful not to slip
Have a change of clothes in a drop bag for changeover from night to day so you stay warm with the big temperature swings
Likely running through the entire night, so have a backup headlamp and/or backup batteries, as it’s about 12 hours of nighttime
