The 27-year-old Van Aert is considered one of the best multi-skilled riders in the world and is a former three-time cyclo-cross world champion and a one-day classics specialist CALAIS, France: Belgian rider Wout van Aert won the hilly fourth stage of the Tour de France and extended his overall lead after attacking strongly on the day’s final climb on Tuesday. The Belgian rider kept the leader’s yellow jersey for the Jumbo–Visma team after taking it for the first time on Saturday. He also extended his lead in the green jersey contest for best sprinter. Van Aert shook up the peloton when he surged ahead up the last of the five climbs — a 900-meter ascent up Cote du Cap Blanc-Nez at a gradient of 7.5 percent — about 10 kilometers (6 miles) from the end. The 27-year-old Van Aert is considered one of the best multi-skilled riders in the world and is a former three-time cyclo-cross world champion and a one-day classics specialist. The Jumbo-Visma rider flapped his hands like a bird’s wings as he sat up on his bike. He crossed the line eight seconds clear of countryman Jasper Philipsen of the Alpecin–Fenix team, with Jumbo-Visma teammate Christophe Laporte taking third place in a sprint finish. Van Aert picked up a 10-second time bonus and is now 25 seconds ahead of Yves Lampaert in the overall standings and 32 seconds clear of two-time defending champion Tadej Pogacar. Pogacar’s rival Primoz Roglic, the 2020 Tour runner-up and Van Aert’s teammate, stayed seventh overall and remained nine seconds behind Pogacar, with both finishing in the main pack. After a travel day, riders tackled a sunny 171.5-kilometer (106.3-mile) route from the coastal city of Dunkirk to Calais, where riders could see the English coastline when they arrived into the much-used port location. Van Aert completed it in 4 hours, 1 minute, 36 seconds. Danish rider Magnus Cort, who thrilled crowds with his breakaway rides during three intense days in Denmark, was again in the early breakaway — this time alongside Anthony Perez. Perez pulled ahead some 45 kilometers (28 miles) out and Cort was caught by the peloton shortly after. Cort picked up more points in the polka-dot jersey bid but much more difficult climbs in the Alps and Pyrenees are still to come. Wednesday’s fifth stage is a flat stage for sprinters over 157 kilometers (97 miles) starting at Lille Metropole and going over some of the feared cobblestones that feature on the Paris-Roubaix one-day classic. The race ends on July 24 in Paris.
