Im one of those people that was inspired to take up running from the London 2012 Olympic games. I have completed a couple of Half-Marathon's and 1 full Marathon since investing in a decent pair of trainers. Thing is, I feel as though I am not pushing myself. I want to run faster! In particular I want to run a sub 45min 10K. Right now I'm running it in 55-60 minutes but I'm knocking them runs out like they are nothing now, feel the need to step it up a bit! Can anyone suggest a training routine that would help me increase my running pace and get me below that 45min mark? Thanks.
