What a great attitude. It’s not often that I see high school runners with that attitude. While it’s good to see the killer competitive attitude, that’s what you need to achieve at your best, so many people forget one of the greatest benefits of running is the improvement of duration and quality of life.
Go for it and don’t give up on winning those races in 10 years. However, never forget your goal of running in your 70s and 80s.
