The Lead King Loop 25K course
The 25K dirt road course starts in the quaint and historic town of Marble.
Rounding Beaver Lake, the course then climbs 2900 vertical feet in about 4
miles into Lead King Basin, a beautiful backcountry area. The course then
switchbacks down past waterfalls, rolls through the old mining town of Crystal,
passes the famous 110-year-old Crystal Mill, climbs out of the river valley then
has a fast downhill finish to the lodge. All of this on one of the peak color
weekends of the fall!
