After completing the biggie I.e week 5 run 3, I thought well week 6 run 1 is going to be so easy its laughable! How wrong was I?!!! It wasn't just my usual left calf pain (my left leg always feels as though it's made of lead, right leg is absolutely fine!) But I was just exhausted, like it took every ounce of willpower to get through the 8 min run - after 4 mins I honestly thought I had ran the full 8 mins. Don't understand!!!! What gives?!!!
