Mild temps, headwinds early

Runners will face temperatures starting at 59°F and peaking at 63°F, with 82% humidity. A light headwind will challenge participants from miles 2-8 and again from miles 11-14, making pacing adjustments essential in those segments. Runners should hydrate frequently and consider starting conservatively to account for the humidity. Tailwinds from miles 15-25 will provide relief and may enhance finishing times.
