First thing: what do your running shoes look like? When you look at the bottom, is there any tread left? Have you been running in the same shoes for a year...or more? Any experienced runner will tell you that shoes need to be replaced after about 450-500 miles of use. If you run 45-50 miles per week, then you need to replace your shoes about every ten weeks. If possible, own two or more pairs of running shoes that you alternate each day, to allow each pair to decompress in between daily running.
The number one complaint from new runners is shin pain. The human body can adapt to just about any training regimen, but the adaptation takes time and the adaptation should be done slowly. To get your shins (formally known as the tibialis anterior muscle) accustomed to running, your coaches recommend
running on soft surfaces,
running with short strides (don't let your heels/feet get way out in front of you),
alternate walking with running until you build up endurance in your leg muscles, and
doing Coach Stride's cooldown stretches at the end of every practice.
This YouTube video explains shin pain and gives remedies. It's worth twelve minutes of your time. Watch and learn, and share with a fellow runner!
Soreness and tight/fatigued muscles are to be expected as a high school athlete, but any pain or excessive soreness that lasts three or more days should be discussed with your coaches.
