Warm start, chance of rain

Starting at 68°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. There's a chance of rain, so have a backup gear plan ready. Moderate humidity at 66% is worth noting for effort level, especially in later miles.
