Race Day Weather
Cool start, hilly challenges ahead
Runners will face a temperature rise from 43°F at the start to 67°F by the finish, with average humidity around 52%. Wind speeds will peak at 11 mph with significant headwinds from miles 6 to 13, making those climbs more challenging. Runners should adjust their pacing strategy early to conserve energy for the hilly sections, particularly from mile 11 to 12 where the climbs are steep.
The Leadville Trail 100 Run (aka The Race Across The Sky or the LT100) is an ultramarathon held annually on rugged trails and dirt roads near Leadville, Colorado, through the heart of the Rocky Mountains. First run in 1983, the race course climbs and descends 15,600 feet (4,800 m), with elevations ranging from 9,200 to 12,620 feet (2,800–3,850 m). In most years, fewer than half the starters complete the race within the 30-hour time limit. Wikipedia
