The ultimate treadmill?

Can't even call it a treadmill. It's known as the Woodway Speedboard. Nice concept- no power source and it looks like it keeps well. I wonder would CrossFit affiliates ever bring these into their gyms? By their reasoning for creating it, it looks like they jettisoned any indicator of measurement. Hmm. I definitely would, but only if I could tell how far I ran because CrossFit WODs ask for 400m, 800m, 1600m, 5k, 10k, etc.
