I'm almost defintely not going to do it.

I went for a 5 miler this morning which was fine - heart and lungs are magnificent... But my lower legs (and bum for that matter) are a different story. I am getting pains down the sides of my calves - not achilles area - and my left heel is still aching. As I run I get pain in my upper hamstrings which stabs down my legs from time to time.

I have (almost) decided that it's daft to try and run on Sunday. My big fear is getting to the 10 mile point reasonably OK but then hitting the bit where my toe hurts, my foot siezes up again and there is still more than 3 miles to go, that's over half an hour. I don't want to walk, I most definitely don't want to be struggling along with everyone cheering me on like I'm one of the red-faced plucky but sad cases who feature in the TV round ups. (I had that fear last time)

But there is still a part of me which desperately wants to do this - well, I want to have done it. I have to ask myself if it's worth the risk of injury to do this one run. I can book any number of 10ks which I know I can do (even though I freaked out a bit on the Bristol 10k)

Now I'm sat at work with my little toe hurting, my heel aching and my lower legs periodically spasming. It's not looking good is it?

Perhaps this is where my new life of healthy and varied exercise begins. It was always going to happen after the run, perhaps I just bring it forward a couple of weeks (cos the week following a run is a rest week) and get stuck in.

But I so wanted to cross the finish line in a blaze of glory

Perhaps I will
