Treadmill with a USB interface

It seems like a simple request. I want a treadmill with a USB interface so that I can download workout data. The treadmill's computer already tracks heartrate, mileage, incline, etc. Just slap a USB interface on the side so that I can plug my SanDisk Cruzer into it and download my workout. A simple CSV file with "workout time", "distance", "average heart rate" would be enough to start with. Something like this:

time (minutes),distance (feet),heart rate (bpm)
0,0,75
10,440,80
20,800,95
...

I might actually run inside in the winter if I knew I was collecting data that I could turn into pretty graphs. Plus, I could put it in my annual report :)
