To run or not to run

It's that time of year again. People have started talking about the riverbank run. And once again I am feeling the need to start training. For my 5th 25k? You'd think that just the simple fact that I can't remember if its my fourth or fifth time would be enough of an excuse to not join the masses of people training for it, but every time I see a Facebook status about someone's training, I just can't imagine not being a part of it. So I guess I have no choice but to do it this year again. It's an addiction.
