It is fair to say that Isaac Makwala has taken the World Championships by storm.
After being refused entry to the 200m heats and 400m final because of illness, Botswana’s Makwala was given a second chance and ran a solo heat on Wednesday.
He then qualified from the semi-final to set up a showdown with Wayde van Niekerk in the 200m final.
And his push up celebration after his solo run appeared to strike a cord with fans, too.
Fans across the world took to social media to post impressions of his now famous celebration along with the hashtag #MakwalaChallenge
Even Cristiano Ronaldo appeared to get involved.
