If the temperature is 70° F, then runners will have slower times because it is too cold.

If the temperature is 80° F, then runners will have faster times because it is optimal.

If the temperature is 90° F, then runners will have slower times because it is too hot.

If the temperature is 60° F, then runners will have faster times because it is cooler.
