Lesson learned from week 4 and I started out slowly from the outset. The middle 5 was the hardest actually as my left calf was playing up - again - but the last 5 felt really great and I could have gone on further but played it safe with the leg.
Knowing how hard I struggled, but ultimately achieved on week 4 definitely helped me today. I now know I can run these distances and while R3 is still daunting, I know I can do it....so long as my legs are game!!
