Runners will face a mild start at 60°F, gradually warming to 61°F. Wind will be challenging with headwinds at the start and again at miles 9 and 19, requiring attention to pacing. A moderate average humidity of 70% suggests hydration will be crucial, especially during the initial miles. The light chance of rain should not significantly impact the race, but runners should remain prepared for changing conditions.
