I wish I had the will power to run. All it takes is a little bit of rain, or for it to be too hot, or too cold, or too windy or.... you get the idea.
Need to loose weight at the mo, as put on 5kg over the last several days, eating and drinking way too much. Started eating reasonably yesterday, as well as exercise that doesn't involve the great outdoors.

Perhaps it's because I'm in London, running in the countryside would be more interesting, I imagine.

I know when I was (much) younger, I did about 26 mins, but now that is very unlikely. Afterall that was about 20 years ago. How close did you get to the sub 25km mark?
