Honestly, I want to get into the competative part of cycling. I have one of the biggest drives that anyone has ever seen! Any time I dedicate my time and skill to something I become very good at it. I broke my hips due to strong muscles and weak bones during a growth spurt. I'm nearly 20 so I am almost done growing.
When I first started biking 5 miles a day was unbearable. Now I can do 30 miles in a day and be fine the next day, as far as hip soreness goes.
