We returned to her car , after which I hit the potty and went out for another solo seven . I should have hydrated better all day yesterday and during the early miles of the run . By the time I started hydrating on the second half of the run , it was difficult to compensate for the missed opportunity to replace lost fluid - it takes too long to absorb water , never mind electrolytes . And I was fooled by the cooler temps and left my Sport Beans in the car , thinking , I wo n't need these .

Question: Why should the writer have hydrated better ?
Answer: None of the above choices .Because getting dehydrated has consequences for health and physical performance .Because they returned to someone 's car .Because the writer hit the potty .
