Invited my 9 year old son on W9R2 today. Set off in lovely weather, him on his bike, heading for my usual route along country lanes. He was puzzled at first as I was walkin so I explained about the 5 min warm up walk and that I'd start running when we reached the pub, as I duly did. 1K in he asked again when I was going to start running!!! The huffing, puffing and sweaty shuffle was obviously not fooling him!! Nevertheless I managed 30 mins. Still nowhere near 5K (as you might have guessed!) but I'll work on that. Leaving my son behind next time though. Can't believe it will be by graduation run!
