Nike is to Apple, as Adidas is to . . . Samsung? In the race to make people run, Adidas is gaining steam with this week's European release of miCoach. Like the iPod-based Nike + system, at the heart of miCoach lies a Samsung phone that similarly follows your progress and motivates your workout.

The phone wirelessly tracks data from a chest strap heart rate monitor and a stride sensor that hooks onto your laces (an advantage over Apple's system since it lets you keep your sneakers). Workouts are built and analyzed on a full-service website complete with graphic data and recommendations for your fitness objectives.
