Starting at 64°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temperatures rising to 79°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. Moderate humidity at 69% is worth noting for effort level, especially in later miles.
