Cool, damp conditions, adjust gear

Runners will face cool temperatures starting at 45°F and rising to 55°F by the finish. With humidity at 82% and light winds from the SE, maintaining hydration will be important. A throwaway layer is advisable for pre-race, as it feels like 44°F with rain likely before the gun.
