So I was watching this video on Jim Ryun where he was saying he was cut from every other sport he tried out for in middle school and track and cross country. Then in his first season of xc he goes from being the 21st runner on the C team to being sixth at the state meet. What I'm wondering is how he never noticed his talent for distance sooner and how as a such a great runner he was bad at every other sport. It just seems implausible to me.
