With These 3 Items, You'll Be Running as Fast as a Pro

"The first must have [in running] is a goal. You need to set a goal for yourself," says Joan. It's a belief that has stuck with Joan her entire career. Case in point: During the 1998 Olympic marathon trials, at the age of 50, she hit her goal of running a mid-2:50s marathon after her retirement from competitive running (which happened in 1991). Her time of 2:49:08 set a new US record in the 50+ age category.

Whether you're just starting out or on your 10th marathon, Joan advises to set your sights on an end goal. It can be finishing every run with a smile, completing your first 5k, or hitting a new marathon personal record.
