Olympic Games Day Two: swimming & diving finals - in pictures

After much criticism of empty seats at the 2012 Olympics, even the Aquatics Centre - one of the most popular venues - has plenty of spare seats in the morning swimming session on day two Photograph: Tom Jenkins

Rebecca Adlington, a double gold medalist in Beijing, looks relieved after winning her heat of the women's 400m freestyle in a time of 4:05.75. But the women in the following heat are considerably faster meaning Adlington only qualifies for the final as the eighth fastest Photograph: Tom Jenkins

She will therefore have an outside lane in the main event this evening Photograph: Tom Jenkins

But the Canadians Emilie Heymans and Jennifer Abel are more coordinated - hence the fact they eventually claim bronze Photograph: Tom Jenkins

Britain's first medal hope in the pool is Ellen Gandy, but she finishes eighth in the women's 100m butterfly final Photograph: guardian.co.uk

Next up it's Adlington's turn in the 400m freestyle. This is not her favoured distance and the Frenchwoman Camille Muffat is the clear favourite, but Adlington is going well in fifth position midway through the race ... Photograph: guardian.co.uk

Over the final 100m Adlington accelerates and pulls herself into third position to clinch a unexpected bronze medal! Photograph: guardian.co.uk

She looks as shocked as anyone. And it turns out that her time was faster than her gold-medal winning time in Beijing Photograph: guardian.co.uk

Michael Phelps is sporting a peculiar expression after another disappointing evening in the pool. Yesterday he was hammered by Ryan Lochte in the 400m individual medley, today he and his USA team-mates have been beaten by the French 4x100m freestyle team Photograph: guardian.co.uk

Phelps actually performed well on the second leg of the relay race, but Lochte was overhauled in the final leg in a stunning finish Photograph: guardian.co.uk
