The Aquatics Centre was not sold out to capacity on Saturday morning. There were dozens of empty seats, but those in attendance let their presence be known.

They screamed. They clapped. They shouted, especially when Great Britain's swimmers were at the front of the pack. Anyone who was sleepy after a late night of partying — Friday was the Opening Ceremony festivities, after all — had trouble catching a few minutes of shut-eye in the colorful venue.

Briton Hannah Miley's first-place finish in the fourth heat in the women's 400-meter individual medley (4 minutes, 34.98 seconds) electrified the crowd. There were bursts of eardrum-shattering roars.
