Katie Knowles is in the UK's top 10 for her age at 1,500m and 3,000m

Truro middle distance runner Katie Knowles has moved into the UK's top five 1,500m runners in her age group.

Knowles, 17, took a second and a half off her personal best as she clocked 4.28.15 at the Millfield Classic as she finished sixth in the women's A race.

"It shows everything is moving in the right direction and I should also be able to reduce my PB in the 3,000m as well," she said.

She hopes to qualify for the 3,000m at the World Junior Championships.

Knowles has been selected as one of a handful of young athletes to be mentored by double Olympic champion Dame Kelly Holmes through her "On Camp with Kelly" programme.

And she sees her greatest chance of victory in the 3,000m where she is currently ranked sixth in the UK and 16th in Europe at under 20s, an age group she still has two full seasons left to run in.
