Eliud Kipchoge recently became the first person to ever run a marathon in under 2 hours.
Kipchoge ran 26.2 miles in 1 hour, 59 minutes and 40.2 seconds.
After the event Kipchoge paid homage to Roger Bannister who, 65 years earlier, became the first person to ever run a sub-4-minute mile.
People had tried for over a thousand years, but doctors and scientists claimed that it was physically impossible for a human being to run a mile in less than 4 minutes.
On May 6th, 1954 Roger Bannister did the "impossible", running a mile in 3:59.4.
As amazing as that was, what happened next was even more fascinating.
Just six weeks later someone ran a mile in 3:58.
And a year after that 3 runners broke the 4-minute barrier in the same race!
Bannister had turned the belief that a sub-4-minute mile was impossible into a myth, and at the same time opened the minds of runners around the world to what they could truly accomplish.
None of it would have happened had Bannister not had an unrelenting belief that maybe, just maybe, he could achieve what everyone else was telling him was impossible.
Impossible is a story.
Limits are stories.
Whether they are limits that others have put on us, or ones that we have put on ourselves.
Control that narrative.
Choose to believe.
Roger Bannister did, and in doing so he redefined what was possible.
You could do the same.
