Gordon said having both a short and a long course meant the duathlon was open to all ages.
The short course, for Years 3 and 4, saw participants run 500m, bike 3km and run 500m.
The long course, for Years 7 and 8, saw participants run 1.5km, bike 8km then run 500m. Pupils in Years 5 and 6 can choose which course they participate in.
