On most mornings Cliff Pemble can be found jogging the tree-lined streets of suburban Kansas City. At 51 he can still move his lanky frame with impressive speed-clocking a sub-eight-minute mile. And as the CEO of Garmin he has access to the latest gadgets that track his performance. Circling a lake in a local park, Pemble runs with a green Garmin Forerunner 235 sports watch on one wrist and a black Garmin Vivo-smart HR+ band on the other. The first monitors distance and pace; the second tracks his heart rate and steps. Pemble doesn't listen to music on his runs, partly because he uses the period for "think time" and partly because of a painful lesson. "I got hit by a car once," he says, pausing for a brief rest near the lake's marina. "I learned you have to be attentive."
