MartinH. Thanks, sounds like you've put in a lot of hard work already, you definately seem to have the motivation. I suppose it must be frustrating knowing that you've run sub 37mins in the past, but who knows it could be possible to repeat it, but like you say it's trying to keep injury and illness free - (I think if you get within a minute or two of that would be impressive enough). I know that is my concern over the next few months, especially as i seem to suffer from colds etc.. We'll see how it goes. I did dip under 38 mins for 10K many years ago, and it would be nice to repeat that again maybe next year sometime. I suppose it's one step (literally) at a time at the moment.
