Pole vault world record holder Armand Duplantis was one of four athletes to set new Golden Spike records.
Sweden’s Olympic and world champion, who broke the world record for a 12th time with a clearance of 6.28m at the Diamond League meeting in Stockholm this month, claimed victory with 6.13m in Ostrava.
Duplantis said he was pleased with his performance despite failing with his three attempts at 6.29m and a new world record.
“I felt good with the jumps, considering I felt as though I was operating on less than a full tank,” said Duplantis.
Kenyan teenager Phanuel Koech, 18, also set a meeting record in the men’s 1500m with a time of three minutes 29.05 seconds, while South Africa’s world indoor champion Prudence Sekgodiso clocked one minute 57.16 seconds to claim victory in the women’s 800m.
In the women’s 400m, Bahrain’s former world champion Salwa Eid Naser broke home favourite Tatana Kocembova’s 42-year course record with victory in 49.15 seconds.
