The men's triathlon at the Paris Olympics has been postponed to Wednesday due to poor water quality in the River Seine, with both men's and women's events facing only a 60% chance of proceeding. Meanwhile, Great Britain celebrated its first two gold medals of the Games, highlighted by Tom Pidcock's impressive comeback in men's mountain biking, despite a challenging start for British boxers. Australia also performed strongly, securing four golds, including in the women's 4x100m freestyle relay, alongside two silvers. In swimming, Matt Richards narrowly missed gold but advanced to the semi-finals in the 100m freestyle. Hong Kong's Siobhan Haughey reached the 200m freestyle final, while China's shooting team added to their medal tally with a gold from Xie Yu. Overall, the medal table sees Japan leading, followed by Australia and the USA.
