Great Britain's Jessica Ennis ended day one of the heptathlon with a shared victory in the 200m.
The 26-year-old crossed the line at exactly the same time as Dafne Schippers from the Netherlands, both clocking a time of 22.83s.
For gold medal favourite Ennis, that time is a new personal best.
Meanwhile, fellow Brit Katarina Johnson-Thompson finished fifth in the same race. The 19-year-old also ran a personal best, going over the line in 23.73s.
Ennis now leads the overall standings in the heptathlon with three events remaining.
