For the women, 2015 test event winners Annie Haeger and Briana Provancha will be looking to unseat Australia's Jo Aleh and Polly Powrie and Great Britian's Hannah Mills and Saskia Clark, London's gold and silver medalists respectively. "We're a bit older and wiser now," says Clark on her return with Mills. "Our focus will definitely be on staying calm under lots of pressure, and then delivering a performance that we wouldn't deliver at any other regatta outside of the Olympics. Hannah and I are well-practiced with pressure." Haeger and Provancha are two of Team USA's strongest medal candidates, and they're incredibly well-versed in the conditions in Rio having spent more time here than any other team, they say. The first day of racing is a chance for them to solidify their position among class veterans.
