Cool start, warm finish ahead

Runners will face a cool start at 51°F, gradually warming to 70°F by the finish. With a light ESE breeze and 44% humidity, conditions are generally favorable. The course features a significant descent, particularly from miles 1 to 11, which benefits runners as they adjust to the rising temperatures. It's advisable to maintain a steady pace and stay hydrated, especially as they transition into the warmer finish.

This course drops 1,680 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 51° and finish around 7:57 AM in 70°; typical start-line conditions say 61° then.
