Cool start, warming trend ahead

Runners will face temperatures starting at 54°F and rising to 69°F, with humidity around 70%. A light breeze from the SW at up to 10 mph will provide minimal impact. As temperatures climb, runners should adjust their pacing in the later laps to avoid overheating. Pre-race feels-like temps may drop to 53°F, so a light layer may be beneficial while waiting.
