Yes. It belongs to the Leadville Race Series, which is also known for the Leadville Trail 100 Run and the Leadville Trail 100 MTB.

How should runners prepare for Mosquito Pass?

Training should include sustained climbing, technical descending, and acclimatization above 10,000 feet when feasible. Weather near the pass can change quickly, so required gear and the official race instructions matter.
