Jamaican triple Olympic champion Usain Bolt opened his 2012 season with a sizzling anchor leg as his Racers Track Club logged a world leading time of 37.82 seconds in a 4x100 meters relay Saturday. Despite his impressive run, he was forced to share the spotlight with teammate Yohan Blake, who sounded a warning of things to come at the London Olympics by running the year's fastest 100 meters. The world champion, who teamed with Bolt on the relay, blitzed home in an impressive 9.90 seconds despite an ordinary start to his first 100m of the season. Bolt easily outpaced compatriot and former 100 metres world record holder Asafa Powell to win the relay by 10 meters in cool, wet conditions. Bolt's team of Mario Forsythe, Blake and Kimmari Roach had given him a three meters lead before he added to the distance against Powell of the rival MVP Track Club team, which crossed the line in 38.27. Gebr beats Radcliffe Haile Gebrselassie won a special half-marathon event ahead of the Vienna City Marathon Sunday after chasing and overtaking Paula Radcliffe, who started the race 7 minutes, 52 seconds earlier. The Ethiopian great overtook Radcliffe after 15.3 kilometers (9.5 miles) and finished in an unofficial time of 1 hour, 52 seconds. In the regular marathon, Henry Sugut of Kenya set a course record by winning in 2 hours, 6 minutes, 58 seconds for his second victory in Vienna after also winning in 2010. It was the first marathon on Austrian soil to be completed in under 2:07. Radcliffe, who timed 1:12:03, planned to use the exhibition event as preparation for the Olympics in London in August but saw her training interrupted by bronchitis over the past two weeks. Radcliffe's head start of 7:52 equaled the difference between her and Gebrselassie's personal bests over the 21.1-kilometer (13.1-mile) distance. Biwott, Tirifi win in Paris Kenyan runner Stanley Biwott and Ethiopia's Beyene Tirfi overcame swirling winds and chilly conditions to win the Paris marathon in record times Sunday. Biwott won in 2 hours, 5 minutes, 11 seconds, beating the old mark of 2:05.47 set by his countryman Vincent Kipruto in 2009, despite running into the wind for most of the first 10 kilometers (6.2 miles). Tirfi, who was third in 2010, dominated the women's race in 2:21:39 to surpass Ethiopian Astede Bayisa's mark of 2:22:02 from two years ago. Kenyans rule in Milan Kenyan pair Daniel Kiprugut and Irene Kosgei Jerotich won the Milan marathon in pouring rain Sunday. Kiprugut finished in 2hr 8min 39sec to beat compatriot Nickson Kurgat into second with Ethiopia's Work Biru Gemechu third. Jerotich won the women's race in 2hr 31.07 ahead of Italian Emma Quaglia and Nediat Habtemriam of Eritrea. Before the race began a minute's silence was held in memory of Piermario Morosini who died while playing football for Livorno Saturday.
