Students entered competitions at Stanley Park in Blackpool where they competed against schools from all over the county.
Eilidh Aindow and Ella Hall competed as a team in the Year 8 duathlon competition with Eilidh coming in second after completing six laps on a bike and Ella completing the running section.
Harry Etchells, 14, had to compete with Year 10s because he was the only individual Year 9 representative from across the county.
He said: “The cycling took it out of me and so I was not as strong in the running as I would have hoped. I came fourth out of six, but all the other competitors were a year older than me.”
Overall the Haslingden team shared the winners’ title with a high school from Chorley and all the competitors were awarded medals.
PE teacher Erika Wilson accompanied the team and said: “I am delighted that we were Lancashire Duathlon joint winners for 2017. Well done everyone.”
