I’m happy. I did five kilometers (just over three miles) on the treadmill today, and I actually ran about 90% of it. I’m doing the Nike Women’s Classic 5K Run next month and my goal is to run the whole thing without stopping. Do any of you runners have training tips for me? What’s the best way to build up your endurance for distance running? (Not that three miles is much for you folks, but it’s a hella long way for me.) Should I concentrate on running the distance faster, or is it better to work on running even farther and just expect the speed to come along with it?
