09:05 Rio Olympics athletes at high risk of infection from contaminated water 

The Rio Olympics begin in just over 4 months, and New Zealand is set to send its biggest team ever, around 220 athletes. Over a quarter of those are the sailors, canoeists and rowers who will compete on Rio's contaminated lakes, rivers and beaches. 

Rio based water and environmental scientist, Dr Fernando Spilki, has been conducting regular tests of the olympic waterways, and says athletes are at very high risk of infection, as there are such high levels of fecal matter entering the water; levels comparable to countries like India.

He says his tests found viruses that induce vomiting such as rotovirus as well as Fecal coliforms that could cause cholera, dysentery, hepatitis A and typhoid.

11:20 The kiwi and Aussie cycling team that competed in the 1928 Tour de France

In 1928 the first english speaking team competed in the Tour de France. The Ravat Wonder team was made up of cyclists from New Zealand and Australia. Wellington man, David Coventry happened upon their story in 2012, and was so intrigued he immediatly set to writing a fictionalised version of their race. 

It became his first novel, The Invisible Mile, which was recently named one of four fiction finalists in the 2016 Ockham book awards. 

The book centres on one of the kiwi riders in the team, a fictional character, from Taranaki, for whom the gruelling ride is more of a pilgramage to the world war 1 battle fields that inflicted so much emotional damage on his brother.
