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.

Ennis, along with other British 2012 Olympic gold medal winners, was featured on a special Royal Mail commemorative postage stamp and had a post box on the corner of Division Street and Holly Street in Sheffield city centre painted gold in her honour.
The post box was vandalised within hours but repaired immediately by Royal Mail.

Ennis was honoured in various ways.
Sheffield artist/cartoonist Pete McKee paid tribute to her in a painting showing her driving an open-top sports car.
Prints were to be sold for the benefit of the Sheffield Children's Hospital charity, of which Ennis is a patron.
She was featured on the cover of a special Olympic edition of The Beano as Ennis the Menace.

The label also made use of the company's slogan in relation to Ennis: "Congratulations Jessica – Strong and Northern".
