Adidas on Wednesday introduced the miCoach Smart Run, its new fitness-based smartwatch for runners, just a day after rival Nike introduced the latest update to its own Nike+ Fuelband SE tracker.The GPS-equipped device can track a runner’s location, along with speed and heart rate. It’s also equipped with onboard flash memory to store music. The Smart Run will be available Nov. 1 for US$399. The Smart Run does not connect with a mobile phone, however. Adidas maintains that it is not looking to produce the best smartwatch — but rather, the best running watch.
