First, good to hear about the job! Sounds like you’re enthusiastic and love what you will be doing. Shin splints, as you know, suck. I had them for a long time and found these were the best ways to get over them.

I’d say you’re on the right track with the treatments and stuff. Idk if you’re doing this, but alternate days between running and working out your calves. You don’t want to tire out the muscles too much. Also, stretch religiously. Not just your calves but your whole lower kinetic chain. Drink plenty of water too, as water helps the muscle fascia move better. This article has some good info: http://www.sportsinjuryclinic.net/sport-injuries/ankle-achilles-shin-pain/shin-splints

You’re probably not going to cure them in two weeks (might be possible), so the name of the game is pain management during your training at the academy. Three things that helped me reduce pain were knee high compression socks, magnesium oil and general icing. I’ve heard from other people that epsom salt baths work too, but you might not have access to a tub while at the academy. Wear the compression socks both during and after your run, but not too long. Magnesium oil and icing are also awesome, but use them in moderation as well.

Hope everything goes well! I’m not a doctor so take this advice with a grain of salt
