Course Information

This races takes place on the BLM trail network called Maston in between Tumalo and Redmond in the shadow of Cline Butte. There are views of the Deschutes river, mountains of Central Oregon, and is just a cool trail through the juniper trees and high desert landscape. A relatively flat course with only about 400? of change this race is a good early season race to see how the engine is running without too much demand on the early season legs.

Aid stations will be self service and we are going sans cups again so please bring your favorite contraption to drink from during your race.

Two aid stations along the course.

Refund Policy

Due to the nature and expense of putting on races and in attempts to keep these smaller, local races as affordable as possible, we are unable to process refunds for this race. Please double check your family calendars, and commitments before registering.

In the event of extreme conditions (fire, ice, extreme heat, or other), race directors will work with local public safety and our own medical advisors to determine if the conditions are safe for race participants and volunteers. In the event that conditions are deemed unsafe, race directors may modify or cancel the race at their sole discretion. In these extreme circumstances, as is true throughout the race industry, refunds will not be offered*. Most of the costs involved in producing a race happen long before you go to the start line. None of us have control over the weather, and we all share in the risk involved if Mother Nature intervenes and makes it unsafe to continue with the event.
