"It was absolutely fantastic," Frederiksen said. "We all pulled together and swam really strong to get a fantastic result at the end of it."
Cashmore added: "I think it will really spur the team on and is a really good way to end the meet. It looks really good for 2012 where we will try to come back even stronger."
