Thanks for the advice and support guys. I pretty much know what I need to do, it's just making myself do it!;) I'm off to a good start. I went walking three days during my four day weekend, including an 11km volksmarch on Saturday (the other days were shorter). I just need to keep that up and not find too many excuses. I have a plan for the distances I'm going to walk; now I need to map out some different routes so that I don't get bored.
