Have just completed W9R3. Am no where near 5k, but I can run for 30 plus minutes. It has been hard going and doesn't get any easier, but I guess that's cos you're always pushing yourself! Now to decide whether to go for longer or faster?? I think longer might win the day, speed is not my forte! Also will look at learning to run outside! Don't feel quite as euphoric as I thought - maybe because I can't just give up now I've got here!!
