I am 11 years old and I am a freshman in high school. I'm the youngest one in my grade and I want to be the fastest on varsity. Currently our fastest runner runs a 14:12 5k, 4:06 mile, and a 9:37 two mile. I'm the fastest in the freshman class, my 5k is 17:47, mile is 4:42, and two mile is 9:58. I want to at least be on varsity next year. What can I do to get faster? And also, what are some marthon training advice and workouts. Thanks in advance for any help with my problem.
