Leadville Trail Marathon & Heavy Half
Race Day Weather
Cool start, warm finish ahead
Runners will face a cool start at 45°F, gradually warming to 67°F at the finish. Wind will be light, but expect gusty conditions with a headwind between miles 7-8 and 16-20. Hydration is crucial, particularly as temperatures rise, and runners should pace conservatively during the climbs, especially from mile 11 to 14. A throwaway layer may be useful before the race due to a feels-like temperature dropping to 43°F.
This course climbs 2,861 ft to its high point and back, so we look at it at 2 points, not just the start line. In a typical year, at 9:00/mi, you start at 45° and finish around 10:27 AM in 67°.
