Army Cadet Corporal Jennifer Platt took gold in the girls intermediate high jump at the ACF National Athletics Finals.
The 15-year-old’s winning jump of 1.53m added 3cm to the national record which has stood for 15 years.
After her success at Grantham’s Meres Stadium, Jennifer from Crowland said: “I have been selected for the nationals each year since 2014, however for various reasons I have been unable attend until now.
“So, having waited for this competition for three years, I was keen to do well.
“Also, it was likely to be my last chance as I am hopefully going to Army Foundation College, Harrogate, next March.”
Jennifer is passionate about sport, especially athletics where she excels at high jump and the 100m.

She said: “Beating a record that has stood for 15 years was completely overwhelming.
“I am really proud of myself and I hope to keep improving in the future.”
Her winning jump helped the East of England team see off the challenge from Scotland and take the Army Cadet National Athletics trophy.
This national ACF sporting event, which brings together around 600 athletes from all corners of the UK, has been hosted in Grantham since the mid-1990s but will, like many other cadet sports, take place in Altcar, near Liverpool, from 2018.
