There was good news for Britain from Usain Bolt yesterday ahead of tonight's Zurich meet when he announced that his expanding horizon will include the long jump but does not go as far as the triple jump.
"I think triple jump puts a lot of pressure on your knees," he said. "I don't want to mess mine up."
So Phillips Idowu, as world champion, and Jonathan Edwards, as world record holder, can relax.
Tonight, Britain's Lisa Dobriskey lines up in the 1500m against Maryam Jamal, the Bahrain athlete who beat her in Sunday's final by a tantalising 0.01sec.
