Despite carrying the weight of expectation of a nation in the capital this summer Ennis delivered to add the Olympic title to the world and European crowns she had claimed in preceding years.
At 26, on paper Ennis seems to be primed for at least one or two more attempts to add to her Olympic medal tally at Rio 2016 and beyond.
However the heptathlon is a notoriously brutal event on the joints leaving multi-eventers to typically retire younger than some of their peers.
Ennis has a ready-made exit strategy in the 100m hurdles - an event in which her London 2012 time, 12.54 seconds, equalled that of Dawn Harper's gold-medal dash at Beijing four years earlier.
Ennis toyed with the idea of doubling up in London before eventually choosing to enjoy a few glasses of wine and a rest instead.
And while winning back her heptathlon title from Chernova - the Russian beat Ennis into second in Daegu last year - remains a priority for now, Ennis believes switching to the sprint hurdles could extend her career.
"I think you have a relatively short-lived career in the heptathlon because of the training and the stresses of it on your body, but the hurdles is definitely something I would love to have a serious shot at and hopefully that will give me a little more time in the sport," she said.
"I need to get back into training and train hard and get my focus on the World Championships next year in Moscow, it's going to be big.
"Tatyana Chernova will be there and I'm sure she will want to retain her title so it's going to be a really big competition."
