I'm not trying to advertise...rest assured, I won't get any money for putting this out there. SO, you can be sure that I'm telling you this because of my own experience...
If you want to start running, one of the best things you can do is to take out a subscription to Runner's World.
All the pertinent information you need to know about running, whether it's how to get off the couch or how to buy the perfect shoe, is contained within its pages...not to mention a SHIT load of inspiration and motivation just oozing out of every story and photograph! I'm super cereal. Every time this shiny magazine is dropped off at my door, I get a burst of "Hell YES! I'm so going running today!" Every. Single. Time.
It costs $24 for 2 years of this stuff! So cheap, so awesome. SO WORTH IT.
Go check out the website and start feelin' the urge to pound down the pavement with reckless abandon! It helps soooo much.
