Tahoe 100k

Get ready for an unforgettable mountain adventure in one of the most scenic and challenging ultramarathons on the West Coast. The Tahoe 100K features 11,500 feet of climbing and over 23,000 feet of total elevation change, taking you deep into the heart of the Sierra Nevada on nearly all singletrack trails. You'll reach heights of 9,800 feet, experience sweeping ridge-line views, and pass by Star Lake, Tahoe’s highest alpine lake, a true high-elevation gem. This course is as wild and beautiful as it is tough, and we’re thrilled to have you join us for the journey.
