Jessica Ennis-Hill had to settle for heptathlon silver at the Rio Olympics as Belgium's Nafissatou Thiam took her title. Katarina Johnson-Thompson fell out of medal contention to finish sixth.
Here, we looks at how the seven-event competition unfolded:
Ennis-Hill, 12.84 seconds, 1,149 points overall, first place
Johnson-Thompson, 13.48 secs, 1,053 points overall, 11th place
Ennis-Hill got the defence of her title off to a flying start with her third fastest time since London 2012. Johnson-Thompson was solid enough given the unfavourable conditions.
Ennis-Hill, 1.89 metres, 2,242 points overall, third place
Johnson-Thompson, 1.98m, 2,264 points overall, first place
Ennis-Hill produced her best clearance since before the London Games as Johnson-Thompson stamped her mark on the competition with a British record and equal world heptathlon best.
Ennis-Hill, 13.86m, 3,027 points overall, second place
Johnson-Thompson, 11.68m, 2,904 points overall, sixth place
Johnson-Thompson's gold medal hopes were dealt a hammer blow by a woeful performance, while Ennis-Hill remained firmly in contention, despite a performance down on her season's best.
Ennis-Hill, 23.49, 4,057 points overall, first place
Johnson-Thompson, 23.26, 3,957 points overall, fourth place
Johnson-Thompson clawed back points in the battle for a medal with the fastest 200m run, with Ennis-Hill second fastest to lead after day one.
Ennis-Hill, 6.34m, 5,013 points overall, second place
Johnson-Thompson, 6.51m, 4,967 points overall, third place
Ennis-Hill was short of the distance she would have been hoping for as Thiam moved into the lead, Johnson-Thompson laying to rest the demons of last year's World Championships when she failed to record a distance.
Ennis-Hill, 46.06m, 5,797 points overall, second place
Johnson-Thompson, 36.36m, 5,565 points overall, eighth place
Ennis-Hill lost more ground on Thiam, who threw 53.13m, while her team-mate's medal hopes went up in smoke with a disappointing performance.
Ennis-Hill, 2:09.07, 6,775 points overall, second place
Johnson-Thompson, 2:10.47, 6,523 points overall, sixth place
Ennis-Hill produced a gutsy display of front-running in a bid to make up the near 10 seconds she had to finish ahead of Thiam to deny her gold, but it was not enough. Johnson-Thompson rounded off a disappointing campaign with a respectable fourth place finish in the final heat.
