Cool conditions, strategic pacing needed

Runners will face a temperature range from 50°F to 60°F, with an average humidity of 66%. Winds will be light at 4 mph, but gusts up to 21 mph will create challenging crosswinds in several segments. The toughest conditions will occur during miles 9-13 with headwinds; runners should conserve energy and adjust their pace accordingly. Hydration will be key, especially if light rain develops.
