Events : There are generally three courses on offer at SENiLe events : Ochre, Olive and Navy. The courses are differing lengths and technical difficulty and are designed to enable a progression to be possible from one course to the next and to ensure that there is something available for your technical ability. The Ochre course will be about 2km long and should be fairly straightforward. Controls should be on obvious line features or right next to them. The next course up, Olive, will be about 3.5km long and should provide a bridge between Ochre and the harder Navy course. Controls may well be a mixture of some controls from the Ochre course and some of the easier controls from the Navy course, possibly starting a little easy and then getting a little more difficult nearer to the end of the course as you get into the swing. The Navy course will be about 5 to 5.5km long and controls can be as hard as they come, provided they are fair. SENiLe events can also be score events. At these events there will be a time limit in which all competitors attempt to find as many controls as possible. There should be a mixture of controls at a score event, some very easy, some hard, some very near the start or finish, some possibly quite a long distance away, and generally not all of them attainable within the time limit. The skill is judging what you can achieve within the time and then continually revising your plan as you progress.

Organisation : Organisation of SENiLe events may be fairly simple. Safety is of prime importance but do not necessarily expect full facilities as the event finances may not allow much in the way of luxuries. Normal controls should be used on the course, with or without electronic punching.
