The best part about running is that unless I want to, I don't have to pay any fees to join a gym, club, group, or employ a personal trainer. Cost is important, because for me, living with the after-effects of cancer diagnosis means my cash-flow isn't as healthy as it was in the past.
I got my running shoes on sale from a shop in the city for $AU 70 and my bra from a department store for around $AU 60. No fancy bells and whistles, no special clothes, no ipod, no timer, no pedometer, no-thing else ... I am set to go!
