Four days after competing at the Shanghai Diamond League, David Oliver had the energy to improve his season’s 110m hurdles best with a win in 13.15 that put him top of the 2015 world listings.
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.

Aided by a 1.8mps tailwind, Schippers finished ahead of world junior champion Dina Asher-Smith, who set a British record of 11.02 while fellow Briton and 2007 world youth champion Asha Philip also set a personal best, clocking 11.10.
Minutes after Schippers’ triumph, another Dutch record fell as Sifan Hassan won the women’s 1000m in 2:34.68, the fastest time in the world for six years
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.
Ostrava, 26 May
Three weeks after suffering a rare defeat at the IAAF World Relays, multiple world and Olympic champion Usain Bolt returned to business as usual by recording his seventh victory at the Golden Spike meeting as, in cold and rainy conditions, he clocked 20.13 in a 200m that was his first individual international race of an injury-dogged season.
“It’s not the conditions I’d like to run my first international race in, but I’m happy that I came away from the race injury-free,” said Bolt. “I just need more races; the more I run, the better I’ll get.”
Sharika Nelvis, broke the long-standing 100m hurdles meeting record of 12.65 set in by Poland’s Grazyna Rabsztyn in 1980 as the American clocked 12.55 into a 1.7 mps headwind.
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,
Olympic triple jump champion Christian Taylor broke the oldest of the Golden Spike’s meeting records – the 16.82m achieved by Viktor Saneyev in 1979 – three times, with a best of 17.52m.
