Put your grit, guts and determination to the test with a 50-mile course that packs more punch (per mile) than even the mighty Race Across the Sky. From technical climbs to heart-pounding descents, the Silver Rush 50 Run takes runners across Leadville’s breathtaking panoramas and under the shadow of 14,000-foot Rocky Mountain peaks. With 8,000 feet of elevation gain over 50 miles, Silver Rush offers the perfect trial run — and qualifying event — for the LT100 Run.
