Cool start, warming finish

Runners will face a cool start at 48°F, warming to 55°F by the finish. A light tailwind will assist throughout the course, but a brief headwind will appear in the final stretch. With humidity at 77%, pacing adjustments may be necessary, especially as temperatures rise. The descent early on will be advantageous, but the climb at mile 19 could be challenging.

This course drops 1,004 ft from start to finish, so we look at it at 3 points, not just the start line. In a typical year, at 9:00/mi, you start at 48° and finish around 1:55 PM in 55°; typical start-line conditions say 52° then.
