Couldn't agree more, Doug. When I was in my thirties I was a very keen cyclist (fun only, never in a competitive way) and I covered thousands of miles a year commuting to work and just cycling for fun. One day we took our two little kids for a picnic in a big open field in Epping Forest. For a laugh, and to the kids' amusement, I took off and ran round the field, around a quarter of a mile.


I couldn't walk for a week. I'm simply not built for running.
