Hey all, so I have started C25k, just wanted to say hi to everyone else on the same mission as me! And see if anyone has any tips/advice to offer. Also do you all run on concrete or grass? I'm on day two so far and have done both on concrete but can feel pain in my hips a bit during and day after. I'm 27 and haven't suffered with this before and i'm new to running so wondered if that was why and il just get used to it! just wanted to see what everyone else finds best? Thanks! Charlotte x
