British cyclist Laura Kenny won the fifth Olympic gold of her career on Friday as she secured victory alongside Katie Archibald in the first women's madison at the Tokyo Games. Kenny was emotional after winning her first gold since giving birth to her son Albie in 2017 and revealed she had considered quitting the sport at one point. "When I fell pregnant, there was a moment two months into the pregnancy where I woke up and said to Jason, 'I can't do this, I'm not going to be able to carry on (with cycling), there's just no way'. And here we are," she said. Kenny's sixth medal overall brought her level with dressage rider Charlotte Dujardin as Britain's most-decorated female Olympian. She also became the first British woman to win five gold medals. Meanwhile, the Netherlands won their fourth Olympic women's hockey title by defeating Argentina 3-1 in the final at the Tokyo Olympics on Friday. After the first quarter ended without any score, the Dutch, who won silver at the 2016 Rio Games, took the lead thanks to a goal by Margot van Geffen off a penalty corner. They extended their lead as Caia van Maasakker netted two more penalty corners. Argentina replied with moments left to play in the first half when Agustina Gorzelany also scored off a penalty corner. Las Leonas kept fighting after the halftime break but were unable to score another goal, settling for the silver medal. Also, Poland's Dawid Tomala cruised to victory in the Olympic men's 50km race walk with a dominant performance over the second half of the race in Sapporo , reaching the top of the podium in just his second completed race of the distance. Antonella Palmisano shrugged off the heat of Sapporo's to win the women's 20k walk to follow up compatriot Massimo Stano's success in the men's race.
