Keely Hodgkinson lowered her personal best and British record with a brilliant performance in the 800 metres at the Diamond League meeting in Paris.
Hodgkinson followed the pacemaker before striking for home 300m from the line, eventually clocking a time of one minute 55.77 seconds, taking 0.11secs off her previous best set in winning Olympic silver in Tokyo.
“I am a little bit shocked that I ran so fast,” the 21-year-old said. “Paris next year, I will definitely be back.
“The weather was really nice, so warm. I had heard good things about the track. With this full stadium and the great crowd, it was amazing. I am so happy.
“Now the aim is to stay healthy, we still have to see, I want to keep running fast. The focus is on the summer, on Budapest (the World Championships).
“What is next with such a fast time early in the season? Well, I do not know. Hopefully I will run even faster.”
Hodgkinson’s record-breaking run came just half an hour after Norway’s Jakob Ingebrigtsen smashed the two-mile world record by more than four seconds.
Ingebrigtsen left the field trailing in his wake as he recorded a time of seven minutes, 54.10 seconds.
Records continued to tumble as Kenya’s Faith Kipyegon set a new world’s best for the 5,000m, just a week after doing the same in the 1,500m in Florence.
Kipyegon produced a blistering last lap to pull away from Ethiopia’s Letesenbet Gidey and clock a time of 14:05.20, taking almost a second and a half off Gidey’s previous mark.
The ideal conditions helped produce another world record in the penultimate event of the evening, Ethiopia’s Lamecha Girma taking more than a second off the previous mark with a time of 7:52.11 in the men’s 3,000m steeplechase.
