Why do I build pedestals high up into clouds aware that I will lose balance and fall before even reaching the top? Why, time and again, do I promise myself the long term unachievable? Am I a fool? An idiot? Why is there yet another empty peanut butter jar by the sink with a spoon in it? Why do the numerous 'I'm 101, have lost 20 stones and can now run 20k in under 15 mins' Lazarus characters fill me with self-loathing rather than inspiration? Which particular bit of the C25K title gave me the impression that to run 5k was a possibility? Why do I sodding care?
