The Pole opened with a foul but soon made amends in the second round, sending her implement out way beyond the 80-metre line. She knew instantly that she had broken the world record and become the first woman to throw beyond 80 metres, and moments later the distance flashed up on the scoreboard – 81.08m.
It added exactly one-and-a-half metres to her own world record of 79.58m set last year in Berlin, making it the biggest single improvement on the women’s hammer world record since 1999.
After all the excitement of breaking the world record in the early stages of the competition, Wlodarczyk regained her composure to complete a consistent series with throws of 79.07m, 78.53m, 76.61m and 77.83m. Alexandra Tavernier of France finished second with 73.33m.
On what was a good day for the host nation’s throwers, world champion Pawel Fajdek won the men’s hammer with 82.07m, once again comfortably defeating Olympic champion Krisztian Pars. The Hungarian finished second with a season’s best of 79.91m.
Two days after winning at the IAAF Diamond League meeting in Stockholm, Piotr Malachowski threw a world-leading 68.29m in the discus.
Double Olympic champion Tomasz Majewski was an easy winner of the shot, throwing 20.78m, while European junior champion Maria Andrejczyk set a national junior record of 62.11m to win the javelin.
