Warm, wet race ahead

Runners will face a warm and humid race, starting at 71°F and peaking at 78°F. With a consistent 7 mph headwind in Mile 6 and tailwinds in Miles 10-11 and 13-14, pacing adjustments are crucial. The moderate rain will lead to slippery conditions, so runners should prioritize grip and consider wearing water-resistant gear. Hydration will be vital, especially with humidity at 93%.
