Greg Rutherford has said that he could break the British record for the 100m if he focused on the track.
The 26-year-old won the gold medal at the 2012 Olympics in the long jump, but has a personal best of 10.26 seconds at the sprint event.
Rutherford told BBC Sport: "I think I could be one of the fastest sprinters in British history if I trained exclusively for the 100m.
"I'm probably not going to get the chance to do that as ultimately I have to stay a long jumper because that's what I do.
"But I think I can run quicker than a few that are around now and possibly cause an upset here and there."
18-year-old Adam Gemili currently holds the British record with 10.05 seconds.
