Like Dianne said, aim small. I used to ring my neighbour 6 doors down and say are you home, I want to walk and I need a rest at your place in the middle. That's what I would do, make it 5mins down to her place and have a bit of a yarn on a chair on her veranda and then walk home. Next up I would walk a small walk along the beach and back to the road to home. Not far, about 15mins round trip and that was good. Now of an arvo I walk 3km round trip along the beach and I must admit I have to push myself to do it at times but I am mostly sticking to every day unless its pouring rain. I want to do a 10k walk soon but I am not sure if I could make it all at once? Maybe I should take a rescue phone with me and phone home if I run out of puff.
