A MapRun 1 hour score event starting from The Crown, Station Road, Chinnor OX39 4EX . The pub doesn’t serve full meals in the evening but does offer bar snacks including loaded fries.
There will be 30 controls to try and get within the 60 minutes. Controls may be found in any order. Controls 10-19 score 10, controls 20-29 score 20, and controls 30-39 score 30. 20 point penalty for each minute or part minute you are over the hour. You may complete as many or as few controls as you want.
The event will use the free MapRun app. This is available on phone, as well as Apple and Garmin watches. It’s advised to have this downloaded in advance of the event. The event is available to downloaded, but is protected by a PIN which you will be given at the event. In MapRun, go to Thames Valley/TVSS/Summer26 and the event name starts ‘Chinnor26’.
Area: Chinnor and the base of the Chiltern escarpment. Mostly roads and footpaths with some grassy areas which will be exceptionally dry and runnable.
Map: 1:10,000 paper street-O map. Solid and dashed black lines show roads and paths respectively. Purple cross-hatch is out of bounds. A solid purple line is an impassable feature. Orange indicates grassy terrain that can be run across if access shown as permitted. Beige denotes fields and other open ground which may not be crossed, other than on paths. Green indicates vegetation that is assumed impassable. Blue is water.
Transport/Parking: Easily accessible from the M40 by car. Approximately 6k pleasant trail running or off-road cycling from either Princes Risborough station or Lewknor Turn (Oxford Tube). Could be attempted by bus number 40 from Lewknor turn. There is a small car park at the pub. If full, there is parking outside the shops on Church Road some 250 metres away (///carver.mugs.incensed) or slightly further away on High Street (///beads.showering.comb).
Starts: 18:30 – 1930, course close 20:30
What to bring: Yourself, in suitable clothing (high-vis highly recommended) and footwear. A phone with plenty of charge. A Garmin / Apple watch if you own one. A compass (not essential). Sunset is at 20:40 so you shouldn’t need a light.
What to expect on the course: As this event uses the MapRun app, there is no physical orienteering infrastructure out on the course. Controls are set virtually, and your phone or watch will register when you have got within a certain number of metres of the specified control site. The finish is located in a cul de sac close to the pub and the start.
