Event Levels (see BOF Events Guideline A for full details):

• A: The most prestigious major competitions, with high-quality organisation and terrain. Age group competition, usually restricted to BOF members. Pre-entry required, but may be limited entry-on-the-day courses for less experienced orienteers.
• B: Less prestigious major competitions, but still on high-quality terrain. Pre-entry normally required for most courses.
• C: Smaller competitions, making use of smaller, more local areas and with fewer courses. Usually entry-on-the-day but sometimes pre-entry will be offered.
• D: Anything else, from "colour-coded" events with 5 or 6 courses down to informal training events designed to provide local competition and increase participation. Entry on the day.

Courses are often described using a colour-coding system:

In general, the darker the colour, the longer and more difficult the course. Juniors and novices can work their way up from white/yellow as they get older and more experienced, whilst the shorter hard courses are appropriate for those with lower levels of physical fitness. Short and, occasionally, long colour variants may be available if the event is large enough. Age class competition can be provided by mapping colours to age classes. Mappings vary depending on the numbers of courses available - see the details for the particular event or BOF Events Guideline B for more information.
