If the runner finished 37th, there are 36 runners faster than him. If he has the 50th slowest slowest time, there must be 49 runners slower than him.
We can therefore conclude that there are 86 runners in the marathon: 36 faster runners + 49 slower runners + 1 the runner we are asked about.
Answer D.
