After the Vuelta a Andalucía in february, it's time for other stage races in France and Italy. Richie Porte and Nairo Quintana get themselves noticed, at Paris-Nice and Tirreno-Adriatico.
During the "course au soleil", Richie Porte won two stages : at the top of la Croix de Chaubouret and at le Col d'Eze during a time-trial. Due to the speed race (25 km/h at la Croix de Chaubouret) and the bad weather conditions (very windy at le col d'Eze), I won't be able to estimate the power for these two stages.
Porte ans his teammate Thomas were really impressive at la croix de Chaubouret. They accomplished the best time for this climb in 24min15s for 10,1 km (6,66% slope). The frenchmen Tony Gallopin, Romain Bardet and Jean Christophe Peraud lost 24s, 30s and 1min06s.
Porte was particularly fast on the last part of the climb : 29km/h during 1,4km (6,8% slope).
The two cyclists from Team Sky, Porte et Thomas, climbed la Croix de Chaubouret 2min20s faster than Landis and Vila in 2006.
Porte took advantage of the work of his teammates Nicolas Roche and Lars Petter Nordhaug during 15 minutes at the bottom of the climb, with a back wind. In 2006, Vila and Landis lost their teammates sooner. The most impressive ride of Landis was during the Tour de France 2006, on the road to Morzine.
The fastest climb ever of la Croix de Chaubouret is still the one in 1997, with Jan Ullrich. This climb happened at the beginning of a a long time-trial, after 12 stages. It's almost impossible to compare this climb in 1997 with the one at Paris-Nice 2015 : different recovery of the last competition days, different hours of stage before the climb, different intensity, and so on.
The day before the climb of le col d'Eze, the frenchman Tony Gallopin won a rainy mountain stage.
He rode alone la montée de Peille and produced 405 watts 78kg-standard (16min47s, 6,2km à 6,88%), around 5.8 w/kg. The other top-riders didn't do better, also because the "hostilities" started in the previous climb when the world champion Michal Kwiatkowski attacked. The bad weather conditions and the distance to the summit could also explain the performance. During the descent to Nice, Gallopin took advantage of the back wind and the crashes of Porte and Thomas.
In Italy, Nairo Quintana accomplished a stunning performance on the slopes of Monte Terminillo. Under the snow, he left behind all his rivals 5km before the finish line.
He produced the equivalent power of 423 watts 78kg-standard, around 6,2 w/kg during 41min20s. The group with Pinot/Contador is around 408 watts 78kg-standard. Thibaut Pinot, in a very good shape early in the season, produced around 5,9 w/kg.
Nibali, the last winner of Le Tour de France is far from his best.
This climb occurs after a 5 hours stage. With these bad weather conditions, Quintana's performance seems slightly stronger than Contador and Froome's at the Vuelta a Andalucía. We could compare Quintana's performance to a 40 minutes climb at l'Alpe d'Huez.
