Real world example:
After 4 years of XC training, my 400 PB has improved from 51 to 48
High school XC or college XC? I find high school XC rather harmless. If you went from 51 to 48 from age 16 to 18, XC may have had nothing to do with your improvement. At some college programs there is pressure on athletes to run a significant amount of miles for XC. At a minimum: Opportunity Cost. How could one have trained more effectively. A college program may have an idea to alter a high school 400m specialist who did not run high school XC into a 400/800 person. Most college coaches know to be careful bringing said athlete along regarding adding mileage. We know athletes who play team sports may be ruined psychologically. We see baseball players for no physical reason unable to throw a ball accurately when the previous season that was not an issue. 400/800 runners may be ruined psychologically with XC if said athlete were not a high school XC athlete. Real world: on my college XC team we were losing a 46.xx 400m psychologically. Coach had an idea of making him a 400/800 man his senior college year. We had to let him be a 400m specialist and just train with the sprinters. Racing JV XC was not for him. Some varsity athletes never should be JV athletes in another sport. Some can take it. Some cannot taking losing in a different sport psychologically well. Your 51 to 48 has not changed my mind that high mileage may ruin some athletes.
