Well I did it, I ran to work and back today, 10km in all, and I even enjoyed it, (although I doubt it showed in my face! ).
So, as weight loss is still very much at the top of my agenda, and seeing as I've very much hit the proverbial wall having lost 18lbs so far this year, I think I'm going to have 4 bike commutes and one run commute per week going forwards.
WOW. Can i have your autograph
