This was a fun idea, and great execution. Imagine running the Boston Marathon in your own home? Well, with iFit Live, you can. iFit Live integrates a Norditrak treadmill with Google Earth.
Utilizing Street View, you can run anywhere you want any time you want. The treadmill automatically adjusts the incline to match the real terrain. The iFit connects you to friends running the same track and can send your data to a personal trainer or physical therapist. A “ghost” of your personal best on a track (so you can compete against yourself) is coming soon.
