The who's who of off-road endurance racing descended upon Colorado this weekend for a double-header weekend of long distance racing at high altitude. 

The infamous Leadville 100, and round four of the Life Time Grand Prix, got things started on Saturday. A grueling 100-mile XC mountain bike course at very high altitudes, the Leadville 100 is one of the most iconic races in North America for mountain bikers and ultra runners alike. The Coloradan race takes place almost entirely above 10,000 feet (3048m) above sea level, and goes up as high as 12,516 feet (3815m). The course also boasts a whopping 13,129’ (4001m) of climbing.
