Leiden Marathon
Race Day Weather
Mild start, adjust for wind
Runners will face temperatures starting at 54°F and rising to 62°F by the finish. Winds will be a factor, with headwinds from the south during miles 1-2 and 19-24, making pacing adjustments essential in those stretches. With humidity at 65%, it's advisable to start conservatively to manage energy levels. Light rain is possible, so a throwaway layer might be useful during the pre-race wait.
