Alberto Contador set a record time this week for the so-called 'Everest Challenge'. The rider who stopped in 2017 took 7 hours, 27 minutes and 20 seconds to conquer Mount Everest's altimeters (8,848).

37-year-old Contador was 2 minutes and 37 seconds faster than Australian Lachlan Morton, who won the 'Everesting record' after two attempts last month.

The first attempt by the rider of WorldTour team EF Pro Cycling was declared invalid, because according to Hells 500, the organization that controls the Everest Challenge, he had covered 450 altimeters too little. Contador therefore drove a little extra to be sure, up to 8,928 altimeters.

The seven-time winner of a big round (twice the Tour, twice the Giro and three times the Vuelta) made his record attempt on the Navapelegrín, a pass just north of Madrid. He rode the steepest part of the climb no less than 78 times (0.96 kilometers at 13 percent) and therefore only needed 139.35 kilometers to reach the height of Mount Everest.

"The madness of Everesting is complete," Contador, fan-urged by fans to make a record attempt, writes on Instagram on Friday. "Thanks for all the messages. It was a tough challenge, but a nice experience."

Hells 500 has now confirmed on Instagram that Contador is officially the new record holder.
