I've been running for a little over a year after more than 20 years as a couch potato. I've lost quite a bit of weight in the past 18months and ran a few races since last winter finishing with the Brussels 20kms in May. I finished it, I enjoyed and I had no aches or pains afterwards, so success! Next challenge? Well of course a marathon, but which one? I've been talking to people and suggestions of Rotterdam and Zurich have come up as fast races so good for starters, any thoughts or suggestions? It seems that Brussels is a tough one so to be avoided, thoughts on this? (I live 15kms from Brussels so of course this would be the easy option for me!) Thanks and happy running!
