Her time of 4:33.34 cut a further five seconds from the personal best that she had set just one week ago. Radus now stands 13th in the UK U17 rankings, while still due to remain in the age group for a further year.

Radus said: “The running conditions were fairly good,  though a little too hot for my liking. I sat behind Kiara Frizelle, the eventual winner, throughout the race in the hope that I would be able to sprint past her.

“She went off really fast and we opened an 11-second gap between us and the third-placed runner. I was unable to sprint for as long as usual because I have had a hip niggle for several days, which was frustrating.

“But overall, considering that I started the season quite badly, I’m delighted to be ending it so well.”

Roger Bruck, 78, brought his season to a satisfying conclusion by successfully defending his 100m, 200m, high jump and long jump titles at the Southern Counties Veterans championships in Kingston.

Bruck retains his top position in the UK V75 annual high jump rankings, stands second in the long jump and has top 10 places for both sprints.
