Although marathons are 26.2 miles (42.2 kilometers) long and take even world-class marathoners over 2 hours to run, athletes who train by running 90 minutes a day fare better in marathons than do those who train by running 120 minutes or more a day.
Why do runners who train by running for shorter periods of time every day perform better than those who train by running longer periods of time?
The correct answer will present an unsatisfactory hypothesis, one that fails to explain why athletes who train on shorter times perform better in marathons. Every wrong answer, meanwhile, will state a difference between runners who train by running 90 minutes a day and those who train by running 120 minutes a day that explains this discrepancy.
