Marathon versenyek Chatsworth közelében

The Mystery Mountain Marathon & 12-Miler is a U.S. trail race series offering two loop-course options: a marathon and a 12-miler. The marathon course includes approximately 2,000 feet of climbing, and the 12-miler has about 700 feet of elevation gain. Both races emphasize hills over pure distance. The event structure is straightforward: participants select either the full marathon loop or the 12-mile loop and race under the Mystery Mountain banner. The available information indicates a mountain-style trail event focused on climbing and uneven terrain, with a shorter option for those who prefer the same course type without the full marathon commitment.
