Midget 15 athletes are 15 year olds, Youth Athletes are 16 and 17 years old, Junior athletes are 18 and 19 years old and athletes in the Senior category are 20 to 34 years old.

The major Championships for these categories are all at the BC Track and Field Jamboree usually held in July. BC sends a team of 15 Midget 15 athletes and 25 Youth athletes to the Canadian Legion Track and Field Camp (effectively a Canadian Juvenile Championship). Youth athletes can try out to qualify for the Canadian team sent to the World Youth Championships. Other meets that are of interest to athletes in these groups are the various Canadian Championships, the Western Canada Summer Games and the Canada Summer Games.

Athletes concentrate on a small number of events (unless they are training for the multievents).
