Location: Hambleden, near Henley-on-Thames on the south Bucks/Oxfordshire border

This event includes the SCOA Championships.

If you are entering the SCOA Championships, you must enter by Age Class, and confirm that you are eligible. Non-SCOA members, may enter by Age Class or Colour.

To be eligible for the SCOA Championships, you must:
– Be a British Orienteering member with SCOA as your nominated Association (as shown on your membership card)
– Enter the class for your age, or ‘run up’. (Note that, as per BOF rule 8.3, women are permitted to be competitive in men’s classes but men are not permitted to compete in women’s classes.)
– Pre-enter by the published closing date shown below.

Medals will be awarded to the first three eligible in each age class. We are considering whether we can hold a COVID-safe medal ceremony on the day. If so, it will be at 14:30hrs. We recommend SCOA entrants ask for a start time no later than 12:30 so they finish in time for the medal ceremony.

Entries now open.

How To Enter


Entries open. Entry is via Fabian4 - see link at top of page. When you enter, you will be asked to select a start time from the list of available start times remaining for your course.

Please enter by Age Class if you are eligible to compete in the SCOA Championships. Everyone else can enter by Age Class or Colour. Results will be provided ONLY by course, not by Age Class.

Note that courses close at 14:45, by which time you must have downloaded. When selecting your start time, please ensure you allow yourself adequate time.

Small family or other groups are welcome (but no more than in pairs), but please enter only the Yellow or Orange courses. Enter as a senior. Change the name if you wish, for example to Jones Family. Add a note in the special request box (step 3 of Fabian4 entry process) to say you are entering as a pair, and we will arrange a second map at no extra charge, so you can both enjoy the navigational experience.


Entry Cost

• Pre-entries up to midnight Sunday 16th May - Seniors £14, Juniors & Students £5. SCOA Champs entries close on this date.
• Late entries (assuming start slots are still available) - Seniors £16, Juniors & Students £6.
• Adults and small family groups on Yellow and Orange £10 (including SIAC hire).
• SIAC hire £2.
• Lost SIACs charged at £65.

If you have a non-SIAC SI card, we do recommend hiring a SIAC, to minimise the risk of infection from touching a control unit in the forest.


A return to Hambleden, with its large car park field and supportive land-owner makes this an ideal area to use given ongoing uncertainty with Covid-19.

We are very grateful to the Culden Faw estate for allowing this event to go ahead. They have asked us to mention the work of the Children’s Air Ambulance, something we are glad to do.

The Children’s Air Ambulance provides a world-class medical transfer service, with specialist facilities so advanced that they can provide intensive care in the air for critically ill babies and children, up to the age of 18.

This is the UK’s only life-saving service of its kind. One of its two, specially equipped, bright green Agusta Westland 169 helicopters is based in Oxfordshire at Kiddlington Airport.
