Just did w1r3 and oh my god! My shins! They are agonising. I didn't actually manage to complete it which was disappointing as i realised that i still had to make it home through the pain. I have been taking it easy at a light jog for my runs and a rest day in between. Stretching at the start and end. But still it's there. Anyone have any help to solve this? I don't want to stop. I need this to work!
