The world champion’s performance was one of four in the Bird’s Nest stadium preparing to host the IAAF World Championships later in the summer to earn a place at the head of the 2015 lists but for the bulk of the 40,000 crowd the high point was a men’s high jump which saw home hope Zhang Guowei earn victory with 2.34m at his third attempt before boldly but vainly moving to 2.40m, a centimetre higher than Zhu Jianhua’s 1984 Chinese, and former world, record.

European indoor 60m hurdles champion Alina Talay won the 100m hurdles in a personal best of 12.70 while in the women’s discus, the in-form Cuban Denia Caballero won with 65.46m and four of her five valid throws would have been enough to win.

Kenya’s Commonwealth javelin champion Julius Yego was ninth after two rounds and in order to remain in the competition he needed a good third round throw. It was better than good, a national record of 86.88m that earned victory.
However, David Rudisha made it only around the first bend of the 600m before pulling up injured, clutching at the front of his thigh. “It’s very unfortunate that I pulled my muscle just after 100m,” he said. “But it’s not a very serious injury.”
Poland’s Adam Kszczot caught Mark English just before the line to win in 1:16.02,
