Don't forget that almost every school has track scholarships and very few give cycling scholarships.
I did track in highschool, messed up my legs, and then moved to cycling in college because I still wanted to compete but couldn't run track anymore. I wish I would've started earlier. Cycling is much more fun than track, and I actually enjoy training. In track, the only part I enjoyed was two seconds before the gun went off to right when I crossed the finish line. I just love competition, but not running. The only reason I kept doing it was because I was good at it and liked beating people in races.
