Niigata City Marathon
Race Day Weather
Comfortable temps, chance of rain
Starting at 62°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Light winds shouldn't be a major factor for pacing. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 76% is worth noting for effort level, especially in later miles.
