British endurance runner Sam Haughian has died after a car crash in Johannesburg, South Africa.
Haughian was fifth in the Commonwealth Games
Haughian was in the final week of a warm-weather training campaign, preparing or a tilt at the 5,000m in this summer's Olympic Games.
His physiotherapist Rebecca Wills was injured and is in hospital.
"This is tragic news and difficult to take in," said UK Athletics chief executive David Moorcroft. "Sam was an extremely talented athlete."
Zara Hyde Peters, head of potential for UK Athletics, said: "Sam was one of my three musketeers along with Chris Thompson and Mo Farah, who were training in South Africa with him until a couple of days ago.
"So many people have been so negative about our endurance running standards
and Sam was one of the bright spots.
"He was a club runner, a team player and a world class athlete in the making."
The best year of Haughian's career was in 2002, when the Windsor, Slough, Eton and Hounslow runner won the AAA 10,000m and finished fifth in the Commonwealth Games 5,000m.
