If you’re able to run a mile without stopping, you’re ready to train for a 5K. If you can cover more like three miles at a time, you can totally handle a 10K. And if you have no trouble laying down five continuous miles, a half marathon is well within reach (you’ll just need a little longer to train). Whatever you choose, you’ll find a the right training schedule below, but don’t freak if it doesn’t fit your schedule exactly. "It’s okay to switch things around a bit within each week to make it work," says Andrew Kastor. "Just don’t do hard workouts back to back."
Worried you won’t be able to keep up the enthusiasm? Our training power duo can help there, too. "What got you out of bed and into your running shoes last year (or even last month) won’t work forever, so change it up when you feel your motivation start to flag," Deena Kastor suggests. Post an inspirational photo on your bathroom mirror, download a hot new playlist to your iPod, or come up with a new mantra. Her latest, taken from a U2 song, says it all: "It’s a beautiful day, don’t let it get away."
