I've recently come back from a tour where I lost maybe half a stone after 9 days of doing roughly 40 miles a day. I don;t get the opportunity to do that when at home. I'm lucky if I do 10 a day, and probably only do closer to 5 (what can I say, kids and work).
What I was wondering is, to keep off the weight and maybe loose more, am I better off walking or cycling the two miles or so to my daughter's school and back instead of cycling it, which takes about 15 mins and barely brings me out in a sweat. Walking it would take about half an hour, so that would be about an hour's walk in all.
