Further Information

SI Touch-free electronic timing
The event will have SI Air enabled.  If you do not have a SIAC card you can hire one from us for £2.  If you have an SI card (i.e. non-Air) you are welcome to use it if you wish. Your time, however, will be a bit longer as a result. Our advice, therefore, is to hire a SIAC card for the event.

Event Safety Requirements
A backup lamp and whistle are compulsory and will be checked.
If conditions warrant it, you may be required to carry a hooded waterproof jacket.
We strongly recommend you carry a mobile phone with you. However, mobile phone reception cannot be guaranteed in this area.

Advice for Junior Entrants M/W14 and below
You must satisfy yourself that M/W14s and below (and all junior entrants) are competent night orienteers capable of completing their courses. You may be asked to provided evidence of the competency of M/W14s and below in completing TD4 and night orienteering courses. The Organiser reserves the right to refuse entry to such competitors who cannot demonstrate the necessary experience. Please contact the Organiser for further information if necessary.

Split Start Times
The narrow start window for this event makes providing split start times difficult. We will try to meet such requests as best we can.

Basic tent, campervan and motorhome pitches are available overnight on Saturday 22nd February. Only facilities provided will be water and event toilets.
Fee: £10 when entering the event.
