2004 silver medalist Austra Skujytė outperformed Ennis by 6 cm in the high jump, clearing 1.92m, and in the shot put, where both athletes scored personal bests.
In the 200 metres, Ennis regained the lead, tying with Dafne Schippers at 22.83 seconds, a personal best for both.
On the second day, Ennis initially struggled with the long jump but figured out her marks eventually posting a respectable 6.48m.
She paid for that fast pace, being overtaken by Lilli Schwarzkopf and Chernova who were battling over the silver medal but on the home stretch, Ennis again showed her superiority, passing them both to win in 2:08.65.
Subsequently, the IAAF filed a case with the Court of Arbitration questioning the selective suspension periods of her and five other Russian athletes that made them eligible between 2011 and 2013.
