Tetrathlon is Modern Pentathlon but without horse jumping and is for athletes 18 and younger.
Horse jumping is only compulsory for ages 19 and up in age groups Juniors, Seniors and Masters.
Tetrathlon presents opportunity for all age groups to represent the Province at SA Champs, ages 17-18 Youth A World Champs and Junior Olympics.
