Olympic 800 metre champion David Rudisha is targeting breaking his own world record as he looks ahead to coming years.
Rudisha, who stunned the London crowd when he set the current record time of one minute 40.91 seconds to win gold two years ago, is even setting his sights on going below the 1:40 barrier, he has revealed in an interview with BBC's Extratime.
The 25-year-old's win that night was labelled by some as the greatest race of the Games, with the event's record hardly changing in the last 30 years.
In fact, London's chairman of the organising committee, Sebastian Coe, broke the then world record in 1981, when he clocked a time of 1:41.73.
The fact the record has been lowered by less than a second since then, shows the enormity of Rudisha's aims, something which he is well aware of.
"I've been talking a lot about improving my world record," he said. "Many have been saying that they see I have that potential to even run under 100 seconds.
"I must say it is possible, but it is very tough. To run two laps under 50 seconds, actually, it's not easy."
The 2011 world champion even went as far as saying that if he had not got injured last year, then he may have improved his record already.
The result from 2013's setback was missing pre-season this, and to many he has not yet fully recovered.
Despite leading the Diamond Points Race, Rudisha was beaten into the silver medal position by Botswana's Nigel Amos at the Commonwealth Games.
