Fran Halsall has reached the semi-finals of the Olympics 100 metres freestyle at the Aquatics Centre.
The 22-year-old said recently she would take a gold in that swimming event over anything else and on Wednesday was second in her heat and seventh overall as she qualified for the semi-finals in 54.02 seconds.
Halsall, who finished eighth four years ago in Beijing, has won medals at world, European and Commonwealth level but Olympic gold remains her the dream.
It also emerged on Wednesday morning that Rebecca Adlington, winner of the 400m freestyle bronze, would not be in heats of the 4x200m freestyle relay.
The 23-year-old qualified for the squad in the second trials in Sheffield in June. Her swim placed her as the fourth fastest Briton in 2012 behind Caitlin McClatchey, Rebecca Turner and Eleanor Faulkner.
The trio were all swimming on Wednesday morning with Jo Jackson, whose fastest time this year is 0.02 behind Adlington's, slotting in.
Where possible, British Swimming rest athletes in heats so they can prepare for their individual races and Adlington has the heats of the 800m freestyle on Thursday morning.
Should the quartet reach the final, the team line-up can change and Adlington added to the squad.
While it may bring to mind the mistakes of Beijing, where Adlington and McClatchey were rested, the squad then were title contenders and only included two 200m specialists in Jackson and Mel Marshall.
The line-up was made up with medley specialist Hannah Miley with sprint freestyler Halsall on the anchor leg.
