Cool, rainy conditions ahead

Runners will face cool temperatures starting at 53°F and rising to 56°F by the finish, with light rain expected throughout. A tailwind will aid participants from the start until mile 25, but a headwind will challenge them briefly near the end. With humidity around 79%, pacing adjustments and hydration are crucial; runners should start conservatively to manage the cool and damp conditions.

This course drops 1,004 ft from start to finish, so we forecast it at 3 points, not just the start line. At 9:00/mi, you start at 53° and finish around 1:55 PM in 56°; the start line's forecast says 51° then.
