It's always fun for the experts to gaze into their crystal balls, and "see" who will come out on top in all of these various events. I'm fairly certain that no-one had Pierre-Ambroise Bosse FRA crossing the finish line ahead of his more-fancied rivals in the men's 800m. Close behind was Kipyegon Bett KEN, born 2nd January 1998, and destined to become a serious contender for top honours in the years to come.
Another young gun who had been "making waves" within the men's Pole Vault fraternity was Sweden's Armand Duplantis (featured recently when he scaled 5.90m for the World under-20/Junior Record). His time will surely come, but unfortunately he found 5.65m beyond him here.
In the men's 3000m Steeplechase, two young men came in 9th and 10th, in times close to their bests - Getnet Wale ETH and Albert Chemutai UGA. Only Estelle Raffai FRA made it through to the women's 200m semi-finals, while Agata Zupin SLO could only finish 7th in the second semi-final of the women's 400m Hurdles.
