Tahoe 100k

The Tahoe 100K invites trail runners to embark on an epic ultramarathon adventure through the breathtaking Sierra Nevada mountains. Spanning over 62.9 miles with nearly 11,800 feet of elevation gain and more than 23,500 feet in total vertical change, this race is a true test for endurance athletes seeking a challenging course filled with stunning natural beauty.
Participants will traverse rugged singletrack trails that wind through dense forests and ascend to alpine ridges offering panoramic vistas. The route reaches an impressive elevation of 9,800 feet where runners can take in sweeping views across the mountain range. A highlight includes passing by Star Lake, one of Tahoe’s highest alpine lakes, a serene spot high above the tree line.
This race is designed to push athletes both physically and mentally as they navigate technical terrain and experience dramatic changes in elevation throughout the day-long journey. The event promises an immersive wilderness adventure with breathtaking scenery that will leave participants with unforgettable memories.
