Welcome to one of the most unique and rewarding trail running experiences in the Pacific Northwest.

Reserve Information and Accommodations
The start and finish line is at Jasper Mountain Reserve, Dayton, WA 99328. Type "Jasper Mountain Reserve" into Google or Apple Maps and follow online directions.
Your race registration includes camping and parking on the reserve directly on the race course. On-site camping guarantees an stress-free morning. We suggest arriving during daylight a day or two prior to the race, and departing the day after the race. There will be an informal welcome reception and short presentation about the race at around 9:00PM on the evening prior to the race. BIB-pickup starts at 6pm the evening prior to the race, and we strongly encourage getting it that evening to avoid a morning rush.
Campsites for racers are within Jasper Mountain Reserve. As this is a nature reserve, loud noises, including car engines, power generators, high volume loudspeakers etc. are strictly forbidden. Dogs must be on leash at all times. Camp-fires are only allowed at one designated area (please familiarize yourself with WA State and Columbia County seasonal camp fire restrictions). Bring your own food, water, and (battery) power sources (Jasper Mountain Reserve is off the grid, meaning there is no water or electricity). Portable sanitary facilities will be provided. As there is no garbage and recycling collection service please collect all trash and take it with you when you depart.
Accommodation options are also available just a short drive from the race! Choose from hotels and Airbnbs in nearby Dayton (11 miles from the event), Waitsburg (16 miles), or Walla Walla (37 miles).
Relay Race Details (Start Time 7:00AM):
Relay teams consist of 4 people sharing one assigned bib with an adjustable belt that can be exchanged between team members. Each racer signs up individually and can choose one of the following options:
1) No Team (the race organizers will assign you to a team) 2) Join an Existing Team 3) Create a New Team
All teams start together with the 1st runner of each team running the red loop at the same time. Once completed, the 1st runner passes the bib to the 2nd team member who will complete the green loop. Once completed, the 2nd team member passes the bib to the 3rd team member who will complete the black loop. Once completed, the 3rd team member passes on the bib to the 4th team member who will run the red loop, followed by the 1st team member who will run the green loop, followed by the 2nd team member who will run the black loop and so on, until all 4 team members each have completed all three loops for 12 loops total. Race timing will provide results for entire teams as well as individual times (splits) on each separate trail loop. All three loops combined are exactly 13.1 miles, the distance of a half marathon.
The relay race is expected to take 8-12 hours and the race course closes at 7pm. If a team is at risk of not completing the race by 7pm, the race director will work with that team to double or triple up runners to ensure completion.
