Ackworth School pupil Holly Kitching won the Yorkshire Biathlon championship for her age group in York.
Holly, of Normanton, competed against girls from all over the Yorkshire region and came out victorious after a stunning run.
The biathlon event comprises of a swim and a run and the times for each event are converted into points for a combined total.
Holly competed in the under 15 girls age group which had a 200 metre swim followed by a 1,600 metre run.
She was sixth after the swim so she knew only a fast run would secure victory.
Holly said: “ I knew I had to have a fast time in the run and I was really pleased to come first which then gave me enough points for the outright win.”
Holly now qualifies for the National Schools Biathlon Championships at Queen Elizabeth Park in London next March.
Holly is a member of the City of Wakefield Swimming Club and Wakefield Harriers.
