Ennis' first-day score included two personal bests: 12.54 seconds in the 100 metres hurdles and 22.83 seconds in the 200 metres. Her time in the 100 metres hurdles was a new British record and also the fastest time ever run in a heptathlon.

Ennis achieved another personal best of 47.49 metres in the javelin and won the final event, the 800 metres, in a time of 2:08.65. The following day Ennis announced she would not compete in the 100 metres hurdles individual event. Her time in the heptathlon 100 metres hurdles would have gained her fourth place in the individual final, and her time in the 200 metres would have placed her seventh in the individual event.
