Former world silver medallist Fran Halsall let her intentions be known as she equalled the second fastest time in the world in the heats of the 100 metres freestyle at the Olympic trials.
The 21-year-old, second in Rome in 2009, had already booked a spot on the team in the 100m butterfly earlier in the week meaning she could relax ahead of the freestyle in the knowledge she would be at the Games this summer.
On Wednesday morning she had plenty in reserve as she posted 54.14, ominous for her rivals and the same as American world sprint relay champion Amanda Weir posted in January.
Amy Smith was second in 54.71 with Tuesday night's winner over four lengths Rebecca Turner setting another new personal best in third.
Turner eclipsed world and Olympic medallists on Tuesday to win the 200m freestyle, training in Hannah Miley's 25-metre, four-lane pool clearly paying off.
She returned to set a new personal best in the 100m freestyle, going below 55 seconds for the first time as she touched in 54.95.
Two-time Olympian James Goddard led the way in the 200m individual medley, his sole event after shoulder problems forced him to give up the backstroke last year.
Goddard was fourth at last year's World Championships in the medley where his rivals include Michael Phelps and Ryan Lochte, the latter breaking the world record in Shanghai.
On Wednesday the Commonwealth champion touched in 2:01.52, Ieuan Lloyd and Joe Roebuck also through.
