forgot to say .. keep at everyone, feeling fit is a great feeling.. the personal goal worked well for me when coming back from an injury which stopped me walking never mind running for 3 or 4 months back in Hong Kong, We lived on Lantau Island at that time just by a ferry pier and one day as came round the headland i noticed a sitting out area (pagoda shaped) on top of a long rising ridge not so far from our place and decided I was going walk up there as my 1st effort in getting back into training. I got my pedometer(no smart phone then) and set off next morning, took over 50 minutes to do just the 4km but I decieded there and then that I would get that down to under 25. Went out either every morning at 6am or evening around 8pm for just a month or so and just watched the time come down. 3 months later it was just the 1st marker on my 20km run around the villages and over the peaks. The key as others have said is to get started and then keep challenging yourself.
