Runners will face a temperature increase from 51°F at the start to a peak of 69°F. Wind speeds will reach up to 12 mph, with headwinds affecting miles 6, 13-17, and crosswinds throughout. It's advisable to start conservatively due to the warming trend and maintain hydration, especially as the course turns more challenging in the later miles with persistent winds.
