Cool start, headwind challenge

Runners will face a starting temperature of 62°F, cooling to 51°F, with a steady headwind throughout miles 1-24 reaching 25 mph. The average humidity of 70% suggests potential fatigue, urging runners to hydrate frequently. Strategy should include pacing conservatively in the first half due to headwinds, while the final miles will benefit from a crosswind as they approach the finish.
