Where do you start to begin sprinting professionally?

Who can I talk to, who should I approach etc

First You need to get down to your local athletics club and then you can enter into races. If your good enough you will get a medal at the state or county championships...to be a pro it needs to be gold really and then you ask about the county or state team or as we have in england the English Schools Competition which is the elite runners from around the country......that is where you will get scouted for the Olympics!

But you need to very fast. like if your U13 then about 12.9 for 100m U15 then about 12.0 and if U17 then you need to be running like 11.4 on a slow day!

Hope that was some help! dont give up!
