Thanks for all the advice guys, much appreciated.
I went for a 'run' this morning! I say run, it was more like a fast walk with a bit of a jog every so often! I had my sports bra on and my playlist was all dance music to keep me going! And although I had trainers on, they were not running trainers, I will purchase some though after all the advice :-)
I do keep meaning to watch Eddie Izzard's Marathon Man but haven't got round to it yet....
