Plateau de Beille - Dutch rider Lars Boom could well have earned himself the nickname 'Sonic' after recording the highest speed so far at this year's Tour de France.
The Astana man clocked 109.08km/h during the third stage last week, according to official data released on Thursday.
The average speed in this year's Tour in the first 11 stages was 42.46km/h.
Boom may yet be overtaken, as riders often reach speeds much higher than 100km/h on the descents, on tubulars under 30mm width.
He will not have the chance to better his speed, though, having abandoned the Tour ahead of the first mountain stage after suffering a fever and aching body.
