Tokyo Para-triathlon World Cup: High levels of E. coli found in water
The swimming section of a Para-triathlon test event in Tokyo has been cancelled after high levels of bacteria were found in the water.

"A completely different race and puts some athletes at a huge disadvantage racing in their tri classification. Disappointing for all."
Shinichiro Otsuka, managing director of Japan's Triathlon Union said: "I'm so sorry for athletes that we could not prepare the competition conditions effectively. It was regrettable."
Britain's Lauren Steadman won gold in the PTS5 category, with team-mate Claire Cashmore in second.
