Park won a brilliant 400m free race from lane 1 - Sun Yang and Paul Biedermann were too busy looking at each other, fell off the pace early on and had to settle for silver and bronze respectively. Sun in particular looked like he had loads left in the tank on the final length but had left it too late to challenge Park. He’ll be fired up for revenge in the 1500m now!
Anyway, Park’s smile is adorable.
