Race Day Weather
Chilly start, headwind challenges
Runners will face a temperature rise from 43°F at the start to a high of 67°F. Winds will peak at 11 mph from the SE, creating a headwind from miles 6 to 13, making those climbs even tougher. With an average humidity of 52%, hydration should remain a priority, especially as the temperature climbs. Adjust pacing on the early climbs and prepare for the tailwind benefits from miles 15 to 21.
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
