Runners will face a temperature range from 48°F at the start to 54°F by the finish, with an average humidity of 83%. A 14 mph crosswind will affect the first nine miles and then shift to headwinds at Mile 10 and again from Miles 13-15, requiring pacing adjustments. Strong tailwinds will assist runners from Mile 18 to Mile 24, making those segments more favorable for faster times.
