How fast did Alberto Contador scale the Passo di Mortirolo?

On the 11 or so kilometres which mark one of the most famous and feared climbs in cycling, 2015 Giro d'Italia champion-elect Alberto Contador yesterday took apart Fabio Aru, his previous closest challenger for GC glory.

But however memorable his ride, the time he took to do it - 45-14 (at 15.52kph) - was not even close to some of the fastest recorded since Marco Pantani scaled the Passo di Mortirolo almost a minute quicker than Miguel Indurain in 1994.

Contador's power output is difficult to estimate, but by way of comparison, Ivan Basso's 2006 44-32 saw him rack up 411 watts on average over the distance; yesterday, Giovanni Visconti - according to his Strava file - was at a 321-watt average in hitting a time of 50-51.

As far as times go, different sources, of course, provide slightly different figures from across the years, but common consent stops the clock for 'Il Pirata' at a stunning 42-40 in 1994.

That record, though, lasted all of two years before being lowered to 42-07 by Ivan Gotti and Pavel Tonkov the very next time the climb featured in the Giro, before Gotti and Tonkov were part of a three-man group, alongside Wladimir Belli, that posted a decidedly pedestrian 45-13 in 1997.

There is some debate as to whether 1999 saw the record broken again - some reports have Gotti and Roberto Heras scaling the peak with Gilberto Simoni in 41-42, others put the trio's time behind that of Pantani.

In any event, since then, Simoni has been the clear stand-out man, featuring in three more of the quickest ascents with times varying between 44-32 (2006) and 47-30 (2004).

Contador was part of a 2008 group which posted 46-12 - alongside Simoni again - and took almost a minute off that this year, but it doesn't look like he is going to be troubling the record books any time soon.
