Live coverage, from the Letzigrund stadium in Zurich, of the Weltklasse, the premier meeting in the IAAF Grand Prix series, and a top-class taster for the World
Championships in Tokyo at the end of the month. An impressive line-up in the men's 110m hurdles features
Britain's European record holder Colin Jackson and America's Greg Foster - they have met twice this year and the score is one victory each. Running against them is Tony Jarrett , who has already beaten Jackson twice this season, and, injuries permitting, the flamboyant Roger Kingdom who set a world record here in 1989. See panel left.
