where do you live, city or rural, if found running on roads painfull, i started running on the moores got a head torch an found it just as easy running at night the moores are very soft and far more enjoyable then a treadmill
I used to run only to try and get fit, like Rhodri on off exerciser, started running again on roads and had a bit o knee trouble, then discovered running on the moores just outside Plymouth, using a head torche at night i find it truly exillarting and I have actually begun to enjoy running for the first time, concentrating on the terrain I find the miles fly by only downside is very smelly wet trainers
