Athlete Katarina Johnson-Thompson says she is "full of regret" that she didn't break the pentathlon World Record.

She won a gold medal, and even broke the British record set by Jessica Ennis-Hill, but the World Record is still held by Nataliya Dobrynska from Ukraine.

To break the record, Katarina would have had to run the 800m section of the pentathlon in under 2 minutes 11 seconds.

Katarina told BBC Sport: "This is a huge breakthrough, but I am full of regret from the 800m."

She said: "I thought I could easily run that time and maybe took it for granted. It could've been a different story. I should've been able to do that."
