In her signature event, the 400m-free, she swam a "good-enough-to-win" time of 4:05.70 and then placed first in the 100m-free swimming a 54.73. (Note: She went out in a 27 for the first 50.)
Days ago Rebecca Adlington swam a 4:02.84, some 3-seconds faster in the event than Pellegrini. This has to give Adlington some confidence especially after she was beaten by Pellegrini at the 2011 Fina World Championships. However, Pellegrini was largely unchallenged in the event swimming by herself for the most part which may have had something to do with a less inspired time.
