How good am at discus throwing?

I'm 14 and 5'9 and 180 pounds but not fat just a little chubby. I threw the discus 121 feet 3 inches and was the top thrower in our division. In the league meet i took home a gold medal. Most of my coaches think i have the potential to make it to the Olympics when I'm older. By the way I'm in middle school and the discus weighs 1 kilogram, equivalent to 2 pounds 4 ounces.
