Adam Peaty qualified fastest for Sunday night’s Olympic 100m breaststroke final to set up a showdown with Chinese rival Haiyang Qin, after admitting that concerns over the sport’s doping controversy are “always in the back of your mind”.
Peaty, seeking to win a third successive gold medal in the event, won Saturday night’s opening semi-final in a time of 58.86, before watching Qin follow up with a 58.93 triumph in the second.
