Why It's Almost Impossible to Ride a Bike 60 Kilometers in One Hour | WIRED

[Anthony.R.Brown]

(The hour record for cycling is very simple. It's just one rider going as far as possible for one hour. WIRED's Robbie Gonzalez explores the physical power needed to push for 60 minutes and the equipment and track choices that can make or break the record.)

But that isn't the same. They go around a measured track, but their actual distance isn't measured. If they went up and down the banking they would travel further but that wouldn't be recoreded - so, not really legitimate. UCI certified perhaps, but not accurate.

Very clear answer!
