Katie Clark from Reading and Olivia Federici from Farnborough compete in synchronised swimming's duet from 15:00

They've put in years of hard work with no funding to get to Rio.

Both swimmers retired after the 2013 World Championships and the sport's funding for GB athletes was cut a year later, but the two returned and successfully qualified for a place at the Games earlier this year.
