You take your health for granted and I had a brain tumour op a couple of years ago and the recovery spurred me to get fit and start running. Hoping to do my first marathon this year, did 10ks and a half last year, with 10k time around 46 mins and the half in 1 hour 45, so feel I have a decent chance of a reasonable time if I can get in to the one I want to run which is Amsterdam.If you're the Williambloke I think you are, you'll know the name Vandergas, thats me. Good luck with the running, maybe run with you one day.
