The Three Kings Challenge was established long ago and serves as a test piece in the lore of the XC ski racing community in Sun Valley. A simple linkup of 3 prominent peaks seen mightily and visibly from town - Glassford (11,602'), Ryan (11,714'), and Kent (11,664') in the Boulder Mountain range. Don't let the simplicity of this objective fool you though, it is a true challenge, testing mountain athletes' routefinding skills, technical ability over loose and exposed terrain, and of course: fitness.
