Jack and Jills Downhill Marathon (Sunday)
Race Day Weather
Cool start, warming finish
Runners will face a cool start at 51°F, gradually warming to 69°F by the finish. Light winds from the WNW at 6 mph will be a non-factor for pacing. A notable descent from mile 18 to 27 will help runners gain speed, but headwinds will challenge them from miles 8 to 27. Hydration will be crucial as the humidity sits at 63%.
