Harborside Half Marathon
Race Day Weather
Cool temps, shifting winds
Runners will face a steady start at 46°F, rising slightly to 50°F. Wind will be a factor with a mix of crosswinds and headwinds, particularly from miles 4-5 and 14. Pacing adjustments are recommended during the headwind stretches, while the tailwind from miles 7-8 and 11 can be utilized for stronger efforts. Humidity at 69% suggests a conservative hydration strategy to maintain performance.
