Cool conditions, wind chill factor

Runners will face a steady temperature around 39°F throughout the race, feeling as low as 31°F due to wind chill. Wind will be a significant factor, with a WNW headwind during miles 4, 6-8, and 13, potentially challenging pacing. Runners should consider a conservative start and stay mindful of hydration, as the humidity is relatively high at 66%. A light layer may be beneficial during the pre-race warm-up.
