Warm afternoon, adjust pace wisely

Runners will face a temperature rise from 58°F at the start to a high of 77°F. With an average humidity of 66%, hydration will be crucial, especially in the warmer late miles. Headwinds on Miles 1 and 7 will require extra effort, while tailwinds from Miles 8 through 19 will provide some relief. Pacing should be conservative early to manage the heat effectively.
