Premier tool for all runners!!

I run to 21 miles to work at least once or twice a week regardless of the weather. This jewel gives me the weather status and best recommendations on what to wear. A very needed tool when you wish to bolt out the door under a tight time schedule. It is also true resource for all a runner needs to start a daily run, training exercise or race as it does the math regarding all steps to set for tempo, speed & easy long runs.
