Planner's comments

Thank you for braving the very autumnal day for a run around Cambourne. The nature of the area means that there is very little detailed navigation required so I had to try and create different challenges as best I could. I tried to create as many route choice options as was practical which reports on the day suggest had the desired effect. The longer courses started with a very long leg which hopefully meant runners had to assess the general layout of the map very quickly or loose time. Apologies to the early finishers who were slightly confused by the lack of kites on the finish controls but given their visibility and the banners I hope this didn't cost anyone much time.

Organiser's comments

Orienteering has had to adapt, like much else, to the current circumstances, but we did not expect to become an aquatic sport. We were very pleased that so many of you were not deterred by the rain and turned up to enjoy the event, and we appreciate your positive comments at download. I realise some Green and Blue finishers were confused by the fact that there was a more prominent finish banner at the second finish. We had to bring our old hand-made twentieth-century (and rather horizontal) finish banner back into service for this event, and I thought I had placed it where it would be easily seen. If I'd put them up the other way round we may have risked confusing juniors heading for their finish, so I hope you will forgive this.

I am extremely grateful to all who helped on the day, including Hazel Bickle and Peter Allen who marshalled a road crossing which was a lot busier than expected - traffic was much much lighter during earlier visits.

I'd also like to thank South Cambs District Council for permission to use their car park and positive attitude in helping us to stage this event.

Terrain and map details

Maps are A4 size, pre-printed with courses, and printed on waterproof paper.   White and Yellow courses are at scale 1:7,500.   All other course maps are at a scale of 1:10,000.

White course is kept clear of roads.   Yellow and Orange courses include a timed-out road crossing which will be marshalled for the benefit of junior participants.  Apart from this, Yellow and Orange courses avoid roads.  

Course from Light Green and upwards will involve crossing roads.  The roads are generally very quiet, but require due care and road sense when crossing, and we have decided not to accept entries for juniors under 17 on these courses.   These courses do not direct runners to any mandatory of marshalled crossing points and there are no time-outs.  

Terrain for courses Light Green and upwards will be a combination of open land with path network, and quiet residential areas with a tree-like network of roads with cut-through paths.
