Cool morning, rolling hills ahead

Runners will face temperatures starting at 55°F and peaking at 64°F, with humidity around 80%. A light, variable wind will not significantly impact performance, but runners should prepare for crosswinds throughout the course. Given the rolling terrain, pacing adjustments will be necessary on climbs, particularly at miles 1, 11, and 15. With a chance of light rain, a throwaway layer may be beneficial during the pre-race warm-up.
