    Im injured at the moment(Im a runner)so Im on the bike to keep fitness up. Ive been doing time trails on the stationary bike in the gym, doing 20km mostly, but 40km aswell. I use resistance at level 7. I've been doing the 20km in 25:30 or thereabouts.
    Whats the time trail world record for 20km(on the road)? I know theres probably no record for a stationary bike so cant really compare the two. But it would still give me a rough idea of where Im at.
    Cheers.

    There is no way to compare. Even if you had an accurate measurement of the watts, a great deal depends on aerodynamics.

    Stationary bike times are completely meaningless as they would need to be properly calibrated, and as Lumen pointed out you then need to consider aerodynamics and wind resistance

    In terms of real records, Chris Boardman did 56.375km in an hour, making his average time over 20km about 21 minutes 17 seconds (and he did almost 3 of them back to back at that pace)

    That's on the track, rather than the road though

    The best thing you can do is try better your own times be it on the gym bike or on the road (assuming similar weather).

    Hill intervals are a great idea too.

    Thats exactly what Ive been doing kenny, trying to shave some seconds off everytime. Just good to have an idea of where you stand in the grand scheme of things. If somebody told me that the world 20km time trial record was 21 minutes, that would motivate the hell out of me. Not saying I would beat that, just saying it would definitely act as a spur for my own efforts.
