Located entirely within Lake Mead National Recreation Area, the run will start at Boulder Beach and lead you onto the paved River Mountain Loop Trail offering a Marathon, Half Marathon, 10K and 5K. This epic run will take you on a journey through time, with views of the largest man-made lake in US history. The January desert-temperatures and views of Lake Mead make this run a must-do! Source
