Starting at 65°F, heat will be a factor from the gun — go out conservative and stay on top of hydration. Temperatures rising to 77°F through the course will gradually increase perceived effort in the second half. Light winds shouldn't be a major factor for pacing. High humidity (86%) will make it harder to cool down through sweat — increase fluid intake accordingly.
