Keely Hodgkinson claimed Team GB's first track and field medal of the Tokyo Olympics as eight were added to the overall total on Tuesday.
The 19-year-old took silver in the women's 800 metres, smashing Dame Kelly Holmes' British record in the process.
It took Britain onto 43 medals, just two shy of the minimum target set by UK Sport prior to the Games, and on course to overhaul the tally of 51 from Beijing in 2008.
American gymnast Simone Biles also provided one of the great stories of these Games, as she returned to action with a bronze in the women's beam.
Here, the PA news agency looks back at the highlights of day 11 at the Games.
Golden start
Britain's sailors got the day off to the perfect beginning as Dylan Fletcher and Stuart Bithell struck gold in the rescheduled men's 49er class and Giles Scott retained his Finn class title soon afterwards.
John Gimson and Anna Burnet later added a silver in the mixed Nacra 17 class, while Hannah Mills and Eilidh McIntyre have guaranteed themselves a medal on Wednesday in the women's 470.
Laugher lines up a bronze
Harrogate diver Jack Laugher, a silver medallist in the individual 3m springboard event in Rio five years ago, recovered from a disappointing display in the synchro earlier in the Games to claim a bronze. Xie Siyi took gold for China, with his compatriot Wang Zongyuan in silver.
Double silver in the cycling
The women's team pursuit squad led by Laura Kenny took silver at the Izu Velodrome behind Germany, who won gold in a world record time, while her husband Jason was a silver medallist in the men's team sprint behind Holland.
Germany utterly dominated Great Britain in the women's team pursuit final, stopping the clock in four minutes 04.249 seconds, winning by more than six seconds.
Jason Kenny missed the first of his three chances to move clear of Sir Chris Hoy's Olympic gold medal tally as Great Britain took silver in the men's team sprint. Kenny, tied with Hoy on six, rode alongside Jack Carlin and Ryan Owens, but the trio were comfortably beaten by all-conquering Holland, who set a new Olympic record of 41.369 seconds.
There was disappointment for the men's team pursuit, reigning champions in the event since the Beijing Olympics in 2008. Ed Clancy had been forced out of the Olympics – and into retirement – by injury, and his replacement Charlie Tanfield was involved in a crash with Danish rider Frederik Madsen in the semi-final as the team left Japan empty-handed.
Biles beaming with a bronze
The American had not competed since she withdrew early in the women's team final last week, citing a desire to protect her mental health. But she ended the Games on a high with a beam bronze. Biles scored 14.0 to finish behind Chinese teenagers Chenchen Guan and Tang Xijing.
McCormack claims boxing silver, with more medals to come
British boxer Pat McCormack was beaten in the men's welterweight final by Cuba's Roniel Iglesias to walk away from Japan with a silver.
McCormack, who progressed to the 69kg showpiece after Irish opponent Aidan Walsh withdrew from their semi-final because of injury, was hoping to win Britain's first boxing gold of these Games. However, all five judges preferred the slicker work of southpaw Iglesias, who won every round on three of the officials' scorecards.
Galal Yafai is guaranteed at least a bronze in the men's flyweight division after reaching the semi-finals, while Ben Whittaker is in the light-heavyweight gold medal match on Wednesday.
London boxer Caroline Dubois has missed out on a medal, suffering a split decision defeat in her women's lightweight quarter-final against Thailand's Sudaporn Seesondee.
Hodgkinson heroics
Britain had three women in the final of the 800m and it was Hodgkinson who led the way with a silver behind Athing Mu of the United States. Jemma Reekie looked on course for a bronze until she was chased down in the final metres by another American, Raevyn Rogers, but still ran a personal best. So too did Alex Bell in seventh.
There was devastation for Adam Gemili, who pulled up with a hamstring injury in his 200 metres heat.
Norway's Karsten Warholm shattered his own world record to win the men's 400m hurdles, clocking 45.94 seconds, shaving almost a second off his previous world best of 46.70secs he set in Oslo at the start of July.
Jazmin Sawyers and Abigail Irozuru missed out on the medals in the long jump final as Germany's Malaika Mihambo took gold. Sawyers finished eighth with a best jump of 6.80m while Irozuru came 11th with 6.51m.
