Regret about quitting track?

What other activities could you possibly be doing? Do track. All sprinters have to try the 400 eventually. There was this one guy who was a 400 runner his whole life. He was an elite, but he wasn't anything special at the elite level. When he dropped his running distance down to the 100m and 200m, he set world records. You may know him as Usain Bolt. Anyway, just saying that you might not always know what distance you're best at. Working hard in track and sports can leave you with memories that will last forever.
