Swimmers Grant Turner and Adam Brown will return to Ponds Forge for the final of the 100 metres freestyle with confidence after swimming within touching distance of the time needed to clinch a spot on Team GB on Saturday morning.
Neither place in the two-length race was taken up in the first Olympic trials in London in March, so the pair are in pole position at the British Gas ASA National Championships in Sheffield, the final chance to gain selection for London 2012.
Brown is already on the sprint relay squad but Turner has yet to earn a swim at the Aquatics Centre where he would join partner Jo Jackson, the 2008 400m freestyle bronze medallist.
Turner and Brown at 49.01seconds and 49.13secs respectively can reasonably expect to dip under the qualification time of 48.82.
Roberto Pavoni has already booked two swims in London in the 400m individual medley and 200m butterfly, which will see him take on the might of Michael Phelps and Ryan Lochte.
The Loughborough swimmer, who was born in Harold Wood, Essex, a short train ride from the Olympic Park, headed the 200m individual medley field in 2:02.85, although he will not contest Saturday's final.
Richard Webb was fastest in the 200m breaststroke (2:17.16) while Jack Marriott heads the non-Olympic 50m butterfly (23.78).
Also in the final will be Harry Needs, roared on by vocal girlfriend Rebecca Adlington whose encouraging shouts of 'Go Harry' reverberated around Ponds Ponds before the race.
Aimee Willmott's 4:40.79 in the 400m individual medley was especially impressive given she is in training and bodes well for London. The Middlesbrough swimmer will compete with world silver medallist Hannah Miley on the first day of competition, July 28 - coincidentally the same date her father Stuart competed for Great Britain at the 1984 Olympics, also in the long medley, finishing 15th.
Jemma Lowe, in the 200m butterfly with world silver medallist Ellen Gandy, led the heats by almost two seconds this morning in 2:09.85 while Anne Bochmann, former four-time European junior champion, heads the 400m freestyle (4:13.20).
