Got to tell a story about a "slow" kid...
In high school in the mid '70s our coach got the bright idea that if he got a boatload of kids to come out for XC... surely some of them could run. So he pretty much asked everybody in the school who didn't play football if they wanted to try it. Coach got lucky. In his second year he got a swimmer to come out. Guy got second in state off of three months training and won the two mile in track that next spring.
We also got some guys who weren't so great. One guy was named Randy Holtz who we affectionately named "Locomotive". Over the course of a few weeks on long run days we assigned one of ourselves to stay back and run with the "locomotive". Whatever we didn't gain in fitness... we gained in spending time with a wonderful and very funny guy who inspired us and encouraged us in our own running. He called me "Chibonee" which he claimed was some native tribe's phrase for "fast little boy". And at the meets he would holler "Run, Chibonee, run" when I would go by.
Randy played guitar, sang and wrote a funny little song called "Don't Feed The Animals"... which was about going to the zoo and getting yelled at by the zoo keeper. He had the cross country team sing back up for him at the school talent show. He brought the house down.
Being around "Locomotive" was one of my favorite memories not just of cross country. But of all of my high school years. So glad the coach didn't "run off the slow guys". My coach ended up coaching for almost 50 years. He had a bunch of teams that won state and had some state medalists. Boatloads of all state runners. One of his runners later broke 4 minutes for the mile. And I bet he had a bunch of guys like "Locomotive" who made all that running worth it.
