Marlette 50K and 10 Miler

Prepare for an extraordinary trail running experience at the Marlette 50K and 10 Miler on August 9, 2026. While the provided information indicated Bilambil Heights, New South Wales, our research consistently shows this acclaimed event is hosted amidst the stunning Sierra Nevada landscape of Lake Tahoe, Nevada State Park, beginning at Spooner Lake. Organized by Big Blue Adventure, this race has earned a reputation as an unforgettable adventure and one of the most scenic running events in the region, drawing between 100 and 500 participants annually. It has also been recognized as an RRCA Nevada State Championship Event.

The Marlette 50K offers a challenging yet immensely rewarding journey through approximately 31 miles of epic Sierra singletrack trails, featuring significant elevation changes with "lots of hills" and sustained climbs. Runners will be treated to breathtaking 360-degree panoramas of the iconic Lake Tahoe, the expansive Carson Valley, and the majestic Carson Range. A unique highlight for 50K participants is the opportunity to take a refreshing plunge in Marlette Lake, located midway through the course, should the warm August conditions call for it. The 10 Miler, spanning approximately 10 miles, offers an equally captivating experience, winding through lush landscapes and providing dramatic views of the canyon and Snow Valley Peak as it loops around Spooner Lake and ventures onto the Tahoe Rim Trail. Starting at an elevation of around 6956 feet, the trails are primarily decomposed granite, offering a runnable surface with some stretches of boulders.

Runners consistently praise the impeccable organization and the awe-inspiring scenery, often describing the experience as "breathtaking" and finding it "impossible not to smile" even amidst the challenge. Aid stations along the course are well-stocked, providing essentials such as water, electrolytes, salty snacks, gels, waffles, chews, and even ice at some locations to help combat the typically warm and dry August conditions. With a 9-hour cutoff for the 50K, the Marlette 50K and 10 Miler promises a memorable day of natural beauty, camaraderie, and a true test of endurance for both seasoned trail runners and those seeking an invigorating adventure.
