The Hanging Flume 50k is an ultra trail race starting and finishing at the historic Uravan Ballpark, consisting of a large loop that runs primarily along engaging abandoned mining two-track and dreamy desert single-track. If weaving through canyons, skirting along slick-rock, and reaching epic vistas puts a smile on your face, then this race is for you. The course is right near the confluence of the San Miguel and Dolores rivers, and explores the rarely-visited yet beautiful desert landscape of Southwestern Colorado.
