Cycling: Dan Martin takes the lead in the Tour of Catalonia

Ireland's Dan Martin won the fourth stage of the Tour of Catalonia and also took the overall lead as Sir Bradley Wiggins lost time on the final climb. Martin, aged 26, attacked and broke clear on the climb to Port Aine Rialp at the end of the 217.7km stage in the Pyrenees. Joaquim Rodriguez and Nairo Quintana were 36 seconds off the pace with Wiggins arriving a whole minute and two seconds back. Martin now leads Rodriguez by 10 seconds in the overall standings with Quintana at 32 seconds and Wiggins at 36. Former race leader Alejandro Valverde pulled out of the race along with his Movistar team-mate Eros Capecchi, after a crash on the most important stage of this year's race. The Spaniard went down around 119km into the stage on a descent towards Seo de Urgel, and tried to ride on for another 10km before abandoning. The peloton briefly waited for Valverde but when it became clear that he was unable to carry on, they began to chase down Martin, who had broken clear with 22 other riders on the first climb of the day and opened up a lead of more than four minutes. Quintana was the first man to attack from the chasing pack and he was eventually joined by Rodriguez, but the two attacked too late and Martin was able hold on easily. Tour de France champion Wiggins lost all his Team Sky team-mates after they were exhausted after chasing the breakaway, and was unable to attack along with Quintana and Rodriguez. Stage five of the seven-day event is a 157km race from Rialp to Lleida which features just one climb and will probably end in a bunch sprint. Here are the odds for the top five favourites to win stage 5 at Bet365: Gianni Meersman - 13/4 Samuel Dumoulin - 8/1 Andrew Fenn - 8/1 Julien Simon - 11/1 Pim Ligthart - 14/1
