Team GB's 4x100m men's relay team finally ended Britain's worlds medal drought when they won a bronze on the penultimate day in Helsinki.
The quartet of Jason Gardener, Marlon Devonish, Christian Malcolm and Mark Lewis-Francis came third in 38.27 seconds as France won gold in 38.08.
Trinidad & Tobago captured the silver in a national record 38.10.
Defending champions USA failed to qualify when they dropped the baton in Friday's heats.
The British squad's preparations for the championships were dogged by injury and illness.
Darren Campbell, part of the line-up that delivered Olympic 4x100m gold in Athens last summer, was forced out by a virus.
And Malcolm had little time to practice with the squad - his arrival in the Finland was delayed as he underwent treatment for a pelvic injury in the UK.
And Gardener, who ran the opening leg in Helsinki, said: "Under the circumstances we did very well - we are pleased to get on the rostrum.
"I did the best I possibly could and we had a great changeover."
Lewis-Francis was also happy to at least make the podium.
"We got a bronze and it's the first (medal) we (GB) have got, so we are are just happy to take the bronze home.
"I struggled through the individual and so I'm pleased because at least I've come away with a medal."
But Devonish and Malcolm admitted their disappointment.
"At the last Worlds we got silver - but then we all know what happened - so we're slightly down," Devonish said.
Malcolm added: "I had a few problems round the bend. I can't make excuses but we'd have liked a better medal."
