Get your ass in gear with a digital running coach. Strap one on and start feeling the shame!
Garmin Forerunner 310XT
THE LOWDOWN: This wrist warrior (with an included heart strap) captures a mountain of data as you wheeze down the block. Afterward ¿you can go on Facebook and share details like calories burned and your ¿Google-mapped route.
THE GOOD: It’s easy. Plug in the USB stick and your data goes online faster than Lindsay Lohan into rehab.
THE BAD: Explaining why you’re wearing a huge neon-orange wrist computer.
THE LOWDOWN: This bare-bones fitness watch works with a chest-strap heart-rate monitor (included) to provide feedback that helps you maximize your effort. Connect it to a $55 FlowLink computer dock (not included) to save calorie/heart rate 411 at polarpersonal¿trainer.com.
THE GOOD: Data from a whopping 99 workouts can be stored in the watch at any given time.
THE BAD: It doesn’t calculate mileage. And it doesn’t look like a Rolex.
Adidas MiCoach Pacer
THE LOWDOWN: This tiny gadget plugs into any portable music player and works with a stride sensor clipped to your shoelaces to determine how fast (or slow) you’re going. A coach shouts updates over the music when you’re tearing it up—or taking your time.
THE GOOD: MiCoach works with any shoes, and the interface at adidas.com rocks.
THE BAD: Its British accent might annoy you into quitting mid-run.
THE LOWDOWN: A USB stick with a built-in digital display slides into a lightweight polyurethane bracelet. After a run, pop the USB into your computer and examine your pace, distance, time, and calories burned at nikeplus.com.
THE GOOD: It’s the simplest gadget we tested, but we found it to be pretty accurate.
THE BAD: Don’t schedule any midnight marathons: The dinky display has no backlight.
