people who take walking breaks in marathons and actually finish faster than if they just run so really: walking never goes out of style.)Run a lap of the track and then walk a few and then run another one and walk a few more.
The goal is getting your body used to the motion and combining running with walking won't make the process so daunting. Some people get caught up in the thousands of running-related products you can buy (and many of them are very helpful).
But if you're waiting around for water packs and hundred dollar leggings thinking it will all of a sudden make running easier, it's time to give up on that dream.
The only piece of equipment you really need is a good pair of shoes. Buy shoes especially made for running (not just sneakers) and then head out the door.
