The adidas miCoach SPEED_CELL is designed to be your on-the-go training partner. Fitting snuggly into the sole of compatible footwear, this tiny device allows you to turn your iPhone or iPod into a data-crunching performance analyzer that records and tracks your workout output.
Capturing key performance metrics every second, this performance-measuring tool tracks a variety of data, including time, distance, speed zones and number of sprints. The SPEED_CELL collects top speed, burst speed and total distance. Its on-board memory stores up to eight hours of data, more than enough to monitor your performance during a long workout, practice or game. What's more, you can instantly view your performance data by wirelessly syncing the SPEED_CELL with your iPhone or iPod via miCoach Connect. After uploading your performance info to an iPhone, you can easily share it with friends on Facebook or Twitter.
Another product that can be used together with this device is miCoach Connect for iPhone/iPod Touch. It allows iPhone and iPod users to add heart rate-based coaching to their existing mobile apps.
Available at adidas.com, the SPEED_CELL costs $70 and comes complete with a replaceable CR2032 lithium battery.
