Athletes from the club compete in a number of different championships at a number of different levels:
| Club Championships | Under 13 and under 15 athletes from the club can compete in this two-day event in July | |
| County | AAA Championships | Anyone either born in Sussex or resident here can compete in the Sussex Champs. Age groups from Under 13 all the way through to Veteran |
| Schools Championships | Entered through school. Age groups from Under 15 (Junior) to Under 19 (Senior) | |
| Regional | South of England Championships | Open to anyone, but if entries for an event are high, some will be rejected, depending on personal bests |
| National | AAA Championships | A certain standard for an event must usually have been attained in the recent past for a successful entry. If entries are low, this may be relaxed |
| Schools Championships | A Sussex squad of about 40 is selected after the County Schools Champs. Again, a standard is expected | |
| BUSA Championships | The student championships - universities enter teams. There are no standards expected, and this is the most relaxed of the major champs | |
There are also representative matches at various times of the year for those lucky enough to be selected.
The schools inter-county match takes place the Saturday following the Schools County Championships, and usually involves the top two from each event in the Under 17 (Inter) and Under 15 (Junior) age groups.
The AAA Southern inter-county matches are usually in August. There is one for the Under 13s, a combined one for the Under 15s and Under 17s, and a separate Senior match. There is also a high standard national Senior event in May, and inter-regional matches for the Under 20s and Seniors, where a South of England team performs.
