With just days to go before the Tokyo Olympics begin, there are concerns that Tokyo Bay, where the swimming portion of the triathlon is set to take place, smells like Bendigo Creek.

The Bendigo Creek-esque wastewater and sewage from Tokyo’s 30 million residents, all have to be treated before flowing into Tokyo Bay.

Triathletes who compete in the Olympics risk losing all their friends and family. Olympic Triathlete Mat Rickman believes its worth it to bring home the gold.

“Smelling like a wet dog at a chicken farm that you can’t wash off is worth Olympic glory” Mr Rickman said.
