Long jumper Greg Rutherford says winning gold at the Beijing World Athletic Championships in August would mean "a hell of a lot".
Rutherford hopes to simultaneously hold the Olympic, World, Commonwealth and European titles with victory in Beijing.
The 2012 Olympic champion was speaking to Gabby Logan on The Olympic Journey, which airs on Sunday at 16:00 BST on BBC Two.
On the show, Gabby looks into what it takes to become a winner, asking whether we can be born to win by the makeup of our genes.
We find out how Rutherford's views on nature versus nurture has steered his training and preparation methods - and how he balances this with being a new dad to his six-month old son.
