Nike+ runners in Germany have a new personal trainer. His name is Miles, and he lives on your computer desktop. We’re not sure if Miles is being tested out in the German market before a worldwide release, or if German athletes need a lot of encouragement to go running, but this 3D desktop widget seems like a lot of fun.

As well as displaying all your running goals and challenges similar to how the current batch of Nike+ desktop widgets operate, Miles also offers an interactive calendar to show which days you run most frequently, a weather forecast, and an integrated RSS reader.

I tried installing Miles myself, which is available from the German Nike+ Web site and it installed, but after a few seconds he mysteriously disappeared. Boo! Maybe a German reader/runner out there can offer some further insight? For those who are thirsty for more, check out the official Miles Movie to explain more.
