Time Trial / Time Trialling / TT

How does that work then? Why doesn't he have the world record?
Is it a case of not telling the governing body he was going for a world record so they'd not checked the course and done all that official bollocks? ie. if you beat the hour record but don't have UCI dude present and the right timing devices and blah blah you're not eligible to claim it?

All that is probably true, but there is also the issue with time/distance records that you can't set one in a race, as you may obtain an advantage by catching your opponent(s). In the good old days, when the professional pursuit was run over 5000m, you could go as fast as you liked but you'd never set the UCI 5km standing start record. Same with the 4km record; Boardman's fastest pursuit is 4:11.114, but his 4km record is only 4:13.353
