Subject: RE: Am i fast enough? Everyone grows and gains strength at different ages, too. When I was in middle school and high school I was always slower than the other kids. I didn't finish growing taller until I was 20, and I started getting fast in college at the mile distance. And now I'm 37 and I've had a couple knee surgeries. I'm not fast at a mile anymore but I do pretty well at long distance events. You have everything ahead of you at age 12. Just focus on distances you enjoy the most and keep training and you will improve. |
