Mechanism

Why it's so fast

Dan Bigham hour record's hour record is distance in sixty minutes, not a top speed. The fast hours are riders who waste as little power as possible on drag and who do not go out too hard.

  1. The rider is the drag

    Most of the air hits the person. The tuck, the suit and the bike shrink that shape. A one-second sprint on a road bike is a different event.

  2. Pacing under rules

    The governing body says what equipment and what track count. The entry cites that mark. An unofficial attempt with illegal positions is not the row.

Context

Background

The UCI release that announced Ganna's record also lists Dan Bigham at 55.548 km on 19 August 2022 at the same velodrome. Guinness says Ganna broke Bigham's 55.548 km. Olympics.com names the same 55.548 kilometres.

The figure is an average speed over the hour, stored in kilometres per hour. Earlier UCI hour marks in that release were not repeated by the other two accounts, so they are not rows.
