Sułek strong in Birmingham heptathlon opener, but Kälin steals the show

Adrianna Sułek made a strong start to the heptathlon in Birmingham, establishing herself as a medal contender. The Polish athlete has returned to the elite level after a disappointing previous season that followed the birth of her son. Her performance in the 100 m hurdles was overshadowed by Switzerland's Annik Kälin, who ran a faster time than Skrzyszowska managed in the 100 m hurdles final.
