Can you tell me if this is a good 200 word essay for my application?

At a young age I discovered I had a knack for running. In Cross Country I took 2nd in the state and was in the top 100 in the Nation at the Junior Olympics. In track I broke 2 records at a middle school meet, one for the mile with a time of 5:36 and the ½ mile in a time of 2:36. I had committed my life to running and loved the sport. But 4 years after I started I got seriously injured; I had intense heel pain that prevented me from running. It prevented me from running for 2 years and even after I healed I couldn’t run as well as I had, the pain never went away. No matter how hard I trained I wasn’t getting faster and it was devastating. I was taking second to those who were once so easy to beat. It was heartbreaking. But I knew I couldn’t give up and this experience has taught me that I need to work for the things I want. It's been one of my hardest struggles in life, but it's helped me learn about hard work and dedication. And that is well worth the pain.
