Dimension Data technology is being used in one of the most prestigious races on the cycling calendar, Tour de France.

Discover some highlights and data from step 10 of the Tour de France, a 167 km race going from Tarbes to La Pierre-Saint-Martin.

Stage Highlights

• It was Bastille Day and after a well-earned rest day in PAU, Le Tour travelled 167 km into the great Pyrénées, for the first mountain stage with an unprecedented finish.
• A simple annihilation and demolition took place, as Chris Froom (SKY) and teammate Richie Porte (SKY) were simply unbelievable, as they dominated the stage.
• With 15.2 km remaining at the start of the final mountain climb, the gap between the chasing peloton and the leading 2 riders stood at 2 min 29 seconds. The Movistar team moved to the front, setting an unbelievable pace to chase down and set up an attack for their leaders Quintana (MOV) and Valverde (MOV). The intense pace destroyed many riders’ chances…as the first mountain stage after the rest day. At 11.5 km to go, the leading rider was caught – a gap of 159 seconds closed in just 3.7 km illustrating just how fast the peloton closed the gap.
• “Vroom” Froome (SKY) made his winning attack with just over 5 km to go, the pace was incredible. He also earned 50 more King of the Mountain points and the Maillot à Pois. On present form, he certainly looks on track to win his second Tour de France title.
• Dutchman Robert Gesink (TLJ) also impressed with his great attack at approximately 10 km to go.
• André Greipel regained the jersey from Peter Sagan as an interesting battle for the Green Jersey unfolds.
