true, but now it's different. I want to do something incredible and prove everyone around me wrong. I'm tired of just sitting around doing nothing. We only get one chance at life. haha I know that sounds really cliche but it's the truth. So to answer your question, I believe it's possible. And who knows, maybe we'll be meeting each other in 4 years. Good luck! Other Answers (4) Run what? Most olympians are well into professional training by 17. Some start old though. Depends on the sport. Remember there are thousands of athletes in all sports that are really good and one or two from a whole country go to the olympics. The gap between reallygood athletes and olympians is BIG. Even if your the best in your city, theres still the whole state and then the whole country. Source(s): I don't know about your country but here in the UK, Olympic athlete selection tends to be elitist despite all the lottery money being pumped into sport. However, good luck but I think you will need a miracle.
