Coal Miner, Roslyn WA

Coal Miner is a mountain trail event based in Roslyn, Washington. The main described route is 51.3 miles with an elevation gain reported between 10,100 and 11,300 feet. The course links Cle Elum Ridge with Sasse Ridge, summits Hex, Sasse and Jolly Mountains, descends Jolly Creek to the Middle Fork of the Teanaway River, follows that river to its confluence with the West Fork, then uses the Big Sandy Trails to return to Cle Elum Ridge and back to Roslyn.

Distances:

  • 50 Miler (51.3 miles, 10,100 to 11,300 ft climb)
  • 100 Miler

The event is intended for self-supported mountain running. Aid is minimal and limited to water and basic calories at stations; the course is not marked. GPX tracks will be emailed before the event and participants must preload them into their chosen map app and use them to navigate. An inReach or similar satellite messenger with an active subscription is required.

Entry requires naming a prior hard trail 100k or longer as a prerequisite. Finish verification depends on submission of the participant GPX track and photographic proof such as selfies at the summit of Jolly Mountain and other specified locations. The start location is the southeast corner of Roslyn Pioneer Park, with a nearby bathroom adjacent to the start. Visit the organization's website for the most recent information.
