19 years old, male, started running around 2 years ago. My height is 6 foot 3 inches, and I weight 185 pounds, with my body fat percentage being in the 15-20% range. My prs are 1:57 in the half marathon from august 2019, and 23:45 minutes in the 5k in a random time trial during training, on a hilly course, in the spring of 2019.
My last race was a half marathon with a time of 2:03 last February, but I had become sick shortly before the run, and it took all I had to finish.
The training that I did for several months before this race looked like this:
Monday: 12 mile run in around 2:10-20
Tuesday: Rest
Wednesday: 6 mile run in around 1:05 + 6 strides
Thursday: 2 mile warm up, 4-6 1k repeats in 4:45 2 mile cooldown
Friday: 3 mile run around 30-35 minutes
Saturday: 2 mile warm up, 20-30 minutes with a 8 minute per mile pace
Sunday: 6 mile run in around 1:05 + 6 strides
Two or three weeks after the race, I time trialed a 5k in 24:20. I continued using the training plan above until I came down with an ankle injury due to a nasty blister altering my stride(dumb, i know) , and I had to stop training for 2 weeks. After I came back, I couldn't even finish an easy 6 mile run without having to walk.
I slowly built back to the previous plan, modifying it a bit, with the aim of running only 5k for a couple of years. I replaced the 6 mile easy runs with a one hour easy runs, so I made it independent of my pace, bumped up the Friday run to one hour, and made the Monday run only a hour and half.
I built back up to this plan, but I have never finished a week without having to cut out something. 3 weeks ago, everything was fine until the long run, having to cut that short, but for the last two weeks, I have barely made it to the second reps of the 1k repeats on Thursday. Even during the warmup, my legs felt a bit heavy. My easy pace is around 11 minutes per mile, and usually my legs feel heavy by the end of the one hour easy runs.
Now, I know that I am really not talented, and on the heavy side of this sport, but if I could finish my workouts and make even just some progress, I would be very happy and satisfied. So, what should I do different, how should I train?
