For newcomers to athletics, the age group structure can be quite confusing.

There are different age groups rules for track & field athletics and for cross country.

The "competition year" runs from 1 October to 30 September.

Track & Field

• Under 9 - Aged 7 or 8 on 31 August within the competition year.
• Under 11 - Aged 9 or 10 on 31 August within the competition year.
• Under 13 - Aged 11 or 12 on 31 August within the competition year.
• Under 15 - Aged 13 or 14 on 31 August within the competition year.
• Under 17 - Aged 15 or 16 on 31 August within the competition year.
• Under 20 - Aged 17 or over on 31 August within the competition year but aged under 20 on 31 December in the calendar year of competition.
• Senior - Aged 20 or older on 31 December in the calendar year of competition.
