There's some sort of pad you lie on. I have no idea what your neck does.

Believe it or not, that bike came second to this recumbent at the world 12 hour champs, who did 248 miles.

Overall 12hr winner was a woman on a regular TT bike at 258 miles!
The overall winner at the 24hr champs was a dude on a TT bike who did 550 miles (!!), second place was a Cruzbike 'bent like the one above at 510 miles.
