Some 180 primary aged athletes from around the district enjoyed the challenge of the Mid Canterbury Primary Schools Sports Association Triathlon at Hampstead School last week.
Now in its 11th year, the triathlon is aimed at students in Years 5-8 and offers a taste of multisport.
Children swam 50m of the school pool, biked two laps (around 3km) of a marked road course, and finished with a final 1.5km run around the school grounds.
Seniors raced first and were followed by juniors.
Race director Claudine Campbell, who is an assistant principal at Hampstead School, said the turnout had been very good this year, with numbers up on previous years.
The triathlon had been held in good conditions, although the water in the Hampstead School pool was a refreshing start to races for athletes.
Pupils taking part this year came from 14 schools, with each school supplying marshalls.
