How to get faster?

Don't worry about your weight! You are are still growing! If I could go back in time, I would give myself this advice a thousand times over. So long as you focus on running and recovering properly, your weight will settle at a number that is good for you. Fixating on weight has sent sooo many talented and dedicated athletes down a pathway of further injuries and poor mental health.

Things that could be really helpful to focus on are: 1. running recovery (are you sleeping enough?), 2. are you in a relaxed head space? (being overly stressed about other life things can have an impact on running and recovery), 3. are you eating enough? (if you are cutting carbs you can really tank your energy levels. If you are cutting fat, you might be messing up your hormone cycling. Check out Shalane's Run Fast East Slow), and finally 4. some of the little things go a long ways! You can spend some time focusing on stretching or foam rolling, doing foot strengthening exercises, or more mobility drills. All of these will help ensure that you stay healthy-- and staying healthy and injury free is the best way to continue to see improvement-- and enjoy running! I believe Lauren Fleshman has written much more on the dangers of focusing on weight and other good things to focus n to improve.

Best of luck in your season! Keep your head up!

My standard advice is: "Listen to your body"

You are in your puberty and you are growing right now. That is normal.

As runners we are obsessed with numbers. I just had a horrible 10k so I know what I am talking about.

Not every race will turn out in a way we think. That's just how it is.

I would say don't worry about your times for awhile. Eventually they will get better but only if you are healthy and not injured.

Be patient, we all have been there.

Yes. Yes it is slowing you down.

Focus on getting better so you can run again. Like others have said, try not to worry about your weight! When you're healthy and training, and fueling enough for your training, your weight will go where it needs to be for you to run consistently and improve sustainably.

If this is a worsening, recurring, or long-term injury for you, visit a physical therapist and do what he or she says to get and stay healthy. Then be smart with your training by sleeping enough, fueling enough, and recovering well. That will get you there. It's frustrating, but if you treat your body right, you'll be back out there running faster than ever soon enough.

7 lbs is hardly a variable. Maybe try swimming or biking. Hill repeats are probably good because you can get some really hard work in without too much mileage.

Sooner or later you should try to run more mileage though, but that's something you have to feel out. The main reason high school runners get injured is because they aren't fully developed yet. When get more mature, you can probably start running way more.
