Katie Ledecky has won “only” one Olympic gold medal, that in the 2012 800 metre freestyle. However, her performances at the 2014 Pan Pacs (5 golds) and 2015 World Championships (5 golds), and her 11 world record swims over the past 3 years, portend well for what she may achieve in Rio. She will likely swim the 200, 400, and 800 freestyles, and possibly both freestyle relays. She will be heavily favored in the 400 and 800 freestyles, and probably a co-favorite in the 200 free. The USA will likely be favored in the 4×200 freestyle relay, but are longshots to win the 4×100 free relay, as Australia is the team to beat in that event. Here are some of the swimming records that Ledecky could chase in the pool at Rio de Janeiro.
