After cancelling the first day of the triathlon, Olympic organisers cancelled the second day of triathlon training in the river Seine planned for Monday after weekend downpours in Paris polluted the waterway but said they were "confident" the medal events would be held this week.

In a joint statement, Paris 2024 organisers and World Triathlon said they had taken the decision to cancel Monday`s swimming training session because "water quality levels do not present sufficient guarantees" to allow it to take place. The triathlon is the first Olympic event due to be held in the Seine, before marathon swimming in the second week of the Games.
