London 2012 Olympics: Yohan Blake sends out warning to Usain Bolt ahead of Games with stunning win in Lucerne In his final race before he joins up with his Jamaican team-mates at their Birmingham training base, Blake made the most of a helpful tailwind of 1.6m/sec to race to a convincing win over compatriot Nester Carter, with Trinidadian Marc Burns third. Both men were timed at 10.00sec. It was Blake's first competitive outing since his double triumph over Bolt in the 100m and 200m in Kingston and underlined again that he will be a powerful threat to his training partner's gold medal ambitions in London. But Blake, 21, admitted that whatever the outcome, he will remain close friends with the triple Olympics champion, whom he credits with helping his development at the Kingston-based Racers Track Club. "Win, lose or draw we are friends, even though it is business and he wants to win and I want to win," said Blake. British pole-vaulter Kate Dennison, who has spent the season mainly in the shadow of UK record-holder Holly Bleasdale, warmed up for the Olympics with a victory in a seasons best of 4.56m. Fellow Briton Danny Talbot, the European 200m bronze medallist, was also in top form as he ran a lifetime best of 20.52sec in last night's 200m "B" race. Having already been selected for London 2012 in the 4x100m relay, his performance may well be enough to secure the one unfilled GB spot in the individual 200m at the Olympics. World bronze medallist Andy Turner, who has been hampered all season by an Achilles problem, finished fourth in the 110m hurdles in 13.48sec in a race won in 13.32sec by American Ryan Wilson. The performance of the night came from little known Jamaican Jason Young, 21, who obliterated his personal best to win the 200m "A" race in a super-quick 19.86sec - the third fastest time in the world this year.
