Anti-doping chief to introduce new code that allows athlete’s team to also be held accountable

No one actually dropped the baton this time, which is progress of sorts, but Great Britain's men's 4 x 100m relay squad still managed to get disqualified in their heat, the fifth time they have done so in the past six major competitions.

Seven of the eight qualifiers for tonight's 100m Olympic final ran under 10 seconds in the semi-finals as defending champion Usain Bolt looked close to his brilliant best once more.

Great Britain shot putter Carl Myerscough waited 12 years for his Olympic dream to become reality.

Five days of action for the British team at the European Championships came to an end in Helsinki last night when Richard Buck crossed the line to secure second place for the men's 4 x 400m relay team. It was a silver lining, one of two on the final day, that took the GB medal haul to seven but after yet another Great British sprint relay disaster it was doubtful that the buck would stop there.

Teenage sprinter Adam Gemili has confirmed he does plan to compete at the London Olympics.

It was on 10 June 1984 that Roald Bradstock took part in his first Olympic trials. "It was in Gateshead, and on my very first throw I pulled my groin," recalls the javelin thrower and professional artist who has come to be known as "the Olympic Picasso". "It was the most excruciating pain. I just had that one throw – 74 metres – with one hand in the air and one hand on my leg."
