I think youre running too much. Running back to back 10 milers on a weekend isnt healthy for your legs in my opinion.
Many lifestyle runners will go out every day but I recommend 3-4 times a week with a day of rest in between and ruck 2-3 times a week with no more than 55 lbs. Try running /marching on only soft surfaces. This may take some effort but remember you are only as good as your feet/legs if you are planning a highspeed career, invest in them wisely as they are two of your most valuable assets.
See
www.jeffgalloway.com (Running Free with Jeff Galloway) and see if he has anything to offer you. Also look at
www.runnersworld.com. Look at some running schedules and then tailor one to suite you and your needs. Notice that they are all staggered in mileage. You might try using a log. Some people like this and it can be useful in identifying activities that lead to injury.
Unless you are training for a marathon it isnt necessary to run so many miles. 5k (3.1 mile) training is more than sufficient for the 2 mile APFT and 10k (6.2 mile) will take care of just about anything else you will come across. You can run longer distances and stay healthy but its not necessary unless you are planning a marathon or mini-marathon. There are training books to do this.
I hope this in some way helps-
