For those people under the age of 19 we have the Junior courses. These are colour coded into grades.
These do not work in the same way as the normal membership grades.
The Junior Grades refer to the Octathalon Junior courses. These start at the Yellow Grade, then Orange Grade, then Green Grade, then Blue Grade and then there are two Brown Grades one for Boys and one for girls and then there are two Black Grade courses one for Boys and one for Girls
