[Could I repeat the 10k trainer]

Week 8, day 3 ends with a 5k run.

 

I you can already run a 5k, you should start at week 9, day 1.

[Apologise for such a basic question]

I've repeated days many times. You just lose your prior information for that particular workout which I think is no biggie.

[FRUSTRATED!!!!!]

There are multiple stretching exercises on Pinterest to aid/avoid shinsplints.

The one I use and that works for me is to stand on a step with your toes hanging over the edge and knees bent (similar to a ski position) and flex your toes up and down as quickly as you can for 30 seconds. Repeat 3 times.
