National and South East League

National level event

What does this mean?

Local events are usually low key and in the 'localised' area, ideal for newcomers to try the sport and Training events are non competitive and used for training and coaching, aimed at members of the club, but they can attract people from neighbouring clubs, and are often ideal for newcomers to try the sport. Regional events attract participants from around the local Region, National events are high quality competitions that will attract people from far away, Major events are Major Events such as a British Championships. Virtual events are where there are no physical controls being used. Your presence at a control is registered using an App on your mobile phone, normally the free MapRun6 App.

Planner's Report

Firstly, my apologies for the delay in getting my thoughts down on paper! It took me a while to recover but I hope you haven’t forgotten the event and that these thoughts are still relevant!

Huge thanks go to Alison Howe for controlling the event – she was the perfect Controller – keeping me in line with BOF requirements (who knew a white course leg couldn’t be longer than 200m?!), providing constructive feedback and advice whilst leaving me to go my own way with the planning (for better or worse!)

Thanks also to Andrew Evans for his overseeing Controller input and help (especially with waking up and collecting controls), and thanks to the huge army of DFOK helpers without whom the event could not have happened.

And so to the courses. I certainly hope you enjoyed running at Westerham, and from the comments I heard most of you certainly did. It’s not an easy area to plan on because of the tough vegetation and road crossings, but I tried to provided challenging courses with plenty of route choice and relatively straightforward controls to avoid you having to thrash about in the brambles looking for a pit in the middle of nowhere!

The junior course competitors remained within the Hosey Common area of the map. I hope you enjoyed seeing one of the Hosey caves and the challenge of making your way through the complex and indistinct path network of the area!

Longer course competitors got to see more of the area – with a long route choice leg crossing over the Squerryes estate and parkland, and for Short Brown and upwards continuing into Limpsfield Chart. The fences here caused a bit of a problem – I didn’t want to use compulsory crossing points as that would have eliminated route choice so hopefully you agreed the solution of stating “fences can be crossed anywhere but less agile (or “the old and bold” as Alison described them) may want to use crossing points worked well.

Most of the longer courses had a leg crossing through the dark green area on Squerryes which some commented on. I think this was a fair leg as path run options were available, and Routegadget and SI Split times show no unusual distribution of times

I did receive a couple of comments regarding the (fairly straightforward) navigation that was required to the finish suggesting it should have been taped. I did wonder about that, but BOF Course Planning Guidance rule 5.1.2 states only - "It is important to ensure that the finish is easily located. A common last control with taped route to the finish will ensure this". Given that the finish was a major path junction I think the requirement that finish is easily located was complied with and tapes were not necessary.

So that’s a wrap from me for Westerham 2024! Our next event on the area is another National and SEL Event on 19 Jan 2025 where we will be celebrating DFOK’s 50th Anniversary and will (hopefully) have some English Sparkling Wine (far better than the French stuff!) for all at the finish. Antoine Pesenti will be planning and I’m sure he will have lots of new challenges for you so hope to see you there!

Directions / Parking

Chartwell is very well signposted with Brown tourist signs from all directions. There will be no orienteering signage until you reach the entrance to Chartwell.

Parking will first use the overflow car park at Chartwell and then we will start to fill the lower of the three tiers of parking in the main car park. The upper and middle level tiers of the main car park must not be used by orienteers. Follow the directions of the parking marshals so that we fill the available spaces in a coordinated order.

There is no charge to use the car park for members of the National Trust and £4 for all day parking for non-members. The membership fee changes take place from each 1 February so you may wish to consider joining National Trust before the event and get an immediate benefit at the event.

There are only three parking machines at Chartwell and queues would be inevitable, especially as all NT members also need to use the machine to get a free ticket. We have been asked to collect car parking monies due on behalf of National Trust. As £4 is not an easy amount to collect with coins, we have decided to collect all parking charges due through racesignup at the same time as you enter. If you are a NT member, you will need to enter your NT membership number.
