CJ Ujah has revealed he turned to meditation because he wanted to find more compassion in his life amid the coronavirus pandemic.
The Team GB sprinter, who is in Tokyo preparing for the Olympics, now listens to a Buddhism audio book and meditates daily.
Ujah missed the World Championships in 2019 with a back injury, having previously helped Great Britain to the 4x100m world title in London two years earlier.
Since then Covid-19 has gripped the globe and the 27-year-old wanted to make a change in his life.
"I looked at Covid and said to myself I could make it a negative situation or a positive one. I drew the positives," said Ujah, who will run in the 100m and 4x100m.
"There are our jobs but when Covid hit you realise there are more important things like our families and friends, people are suffering and people have died.
"It was a sense of compassion to meditate and realise what is important. This is my job and I love it but I want to be in touch with the real world.
"The 100m happens so fast but in that time that is when you have to have a calmness. It's a bit of an oxymoron to be so calm in something so fast but you have to remain calm even though you are moving so fast."
Ujah is a 28-1 outsider for the title with American Trayvon Bromell favourite ahead of South Africa's Akani Simbine.
Bromell has run the fastest time in 2021, 9.77 seconds, but with Christian Coleman serving a ban for missing drugs tests and no Usain Bolt, who has won the last three 100m titles, Ujah believes it is too close to call.
He said: "I understand in terms of the aspect of favourite but he's never gone to the Olympics in this position. I wouldn't call anyone a favourite.
"In terms of consistency you can say he has run the fastest time this year but he has been beaten this year. It's not like a Bolt where you just say 'who's coming second and third?' If you get to the final it's anyone's game.
"No-one has two heads. We all have to race and compete for it."
