56°at start

Light
Dry

Cool temps, light winds, steady pace

Runners will face a consistent temperature of 57°F to 58°F, with humidity at 87%. Light winds will create a headwind in the early miles, shifting to tailwinds between Miles 2-7 and 9-10, which should aid pacing. Due to the humidity, adjusting pace conservatively early on will be crucial to maintain energy throughout the race.
