For me, one of the most emotional moments of the Olympics came after the women’s 4x400m relay race. Finishing fourth and agonisingly close to the podium, Sophie Becker, Rhasidhat Adeleke, Sharlene Mawdsley, and Phil Healy stood shoulder to shoulder, praising one another.
To be an Olympian is to be superhuman; it involves gruelling hours of training and limitless resilience. These women are incredible, their teamwork, inspiring.
