Giro d'Italia power play: Froome's Finestre watts revealed

The power Froome produced on the Finestre and how his ascent matched up to those before

Velon has released the power data of Chris Froome (Team Sky) on the Colle delle Finestre. Three days after releasing the power data of his rivals, including Tom Dumoulin (Team Sunweb), and three days after Froome had ridden into pink. 

When it did release the data, Velon gave us just a snippet of information from this race-defining attack. 

For a 3.02km section of the Finestre, the current holder of all three Grand Tours held 397W on the 9.3% average gradient distancing the likes of Dumoulin and Thibaut Pinot (Groupama-FDJ).

The Brit then enhanced his gap with a stunning descent down to Sestriere, averaging 53.4kmh. 

For his attack, with an average of 397W, Froome would have held around 5.6W/kg. These numbers were only slightly higher than those of Dumoulin, who responded with 395W for the same distance, accounting as for why the gap remained steady on the ascent.

This plays testament to Froome's descent in which he averaged 53.4kmh maxing out at 80.1kmh. Froome built a good chunk of time on the descent of Finestre and Sestriere and exploited the lack of cooperation in the group behind.

It also looks as if Froome targeted this downhill with Sports Director Nico Portal talking Froome through the descent in the team car behind. 

The numbers from Froome are not particularly exceptional. Compared to the next day at Cervinia, attacks from Dumoulin saw Froome ride at 420W for nine minutes in order to defend his jersey with three minutes at higher than 450W. 

It should also be considered that this ascent of Finestre was somewhat slower than previous occasions. In 2015, Mikel Landa scaled Finestre in 1 hour 2 minute and 51 seconds. Froome's time was almost two minutes slower at 1 hour 4 minutes and 20 seconds. 

This was also far from the climbing record set by Jose Rujano in 2011 who climbed to its peak in 1 hour 2 minutes and 9 seconds.

The full power files from Finestre would be useful and would probably help alleviate some of the social media pressure on Froome's miraculous resurgence from off the podium to overall victory. However for now, this snippet will have to do.
