Gravetye & YBT/S HeatSun 17 March, 2024

Near: Turners Hill
Level of event: Regional
Type of event: Race



Planners Comments. Thank you for coming out and braving the weather. Unfortunately for everyone, Gravetye and water don’t go so well! The woodland is much less slippy without the rain and I imagine that drier conditions would have resulted in faster times and a more enjoyable experience for everyone. At the best of times Gravetye is a very physical run - personally I enjoy this sort of gnarly orienteering but understand that it might not be for all. With this in mind I tried to channel runners through the best the woods had to offer. Having now planned on Gravetye twice, I very much look forward to seeing what a different planner can produce at the next event.

A big massive thank you to the most amazing Organiser Kate and her merry team of helpers. Thanks also to Steve for being the most solid and reliable Controller who shared his ideas constructively and contributed to the bettering of the courses. Will Heap

Controllers Comments. Gravetye is rough and tough at the best of times, even without underfoot conditions as wet / muddy as they were today. A couple of weeks ago this event hung in the balance as the car park was almost unusable. Fortunately the surface was then scraped and it was game on, albeit with reduced capacity.

Will spent several months almost completely revising his original map from 2021 and it felt very accurate when checking control sites. Will's courses were physically tough and deliberately slightly shorter than usual and other than minor tweaks, there was very little that I felt needed changing. Kate (supported by Di) was a fantastic organiser and always had everything covered.

It was great to see all the happy smiling youngsters from the four clubs (SO, TVOC, DFOK & MV) competing in the regional heat of the Yvette Baker Trophy / Shield. Both competitions were very close and congratulations go to SO in the Trophy, DFOK & MV in a Shield draw, for booking their places in the final (to be hosted by HH) in July. Steve Jarvis

Organisers Comments. Firstly and most importantly, a HUGE thank you to all the amazing volunteers that made a very rain-sodden event such a great success! In the mud-fest car park - Julia, Joe, Einar, Hal and Mark S and in the assembly car park Mark C and Mark S; on the road-crossing - David W, Kathleen, Tim, Clive, David Y and Amaryllis; driveway marshalls - Samantha, Toby and Ed; on the start - Di, Tommy and Scarlet; on newcomers assistance - Mike T; control collectors - Garry, Alan, Chris, Little Dave, Sarah, Scarlet and Tommy; the awesome Si team - Joe, Les, Penny, Paul and Mike R; the map printer extraordinaire - Mike G and lastly, the reserve volunteers who were on standby to help - Neil, Cliff, John, Simon, Robin, Ian and James. It was fantastic to get so many offers of help and to see lots of new volunteer faces - THANK YOU :)

I hope everyone enjoyed a hot drink and some cake courtesy of our local Explorers - a welcome sight after slipping around the forest. I'm sorry we couldn't arrange better weather but despite the rain, things seemed to run pretty smoothly. No major issues, just a couple of items of lost property - an Osprey rucksack cover and some waterproof trousers. Please get in touch if these are yours so we can arrange a reunion. Kate Turner

Pre event info

This regional event incorporates the South East qualifying heat for the Yvette Baker Trophy/Shield competition for junior club teams.

Regional Series Info

Open to everyone. These events offer a larger range of colour coded courses (including the usual yellow, orange, green, blue) and attract a wider group of people from different clubs. Regional events often offer a white course which is easier than a yellow and ideal for juniors wishing to try it on their own for the first time as there should be a control at every decision point. Seven colours are used with each representing a certain level of difficulty (both technical and physical). The darker the colour, the longer and harder the course.

Terrain Description

Gravetye Estate comprises a mix of working forest with reasonable runnability in most areas. Recent forestry work means the area has improved for orienteering and at this time of year, it doesn't get any better. The area is undulating throughout with evidence of historic ground workings. Some areas have low-level Pendulous sedge and long, whippy brambles which are generally easy to pass through, but the going is physical. Woodland is often edged by brambles but you never have to travel far to find a gap. Fields are often edged with a single strand of barbed wire, sometimes found on the ground - these ruined fences are easily crossable and shouldn't represent a barrier when planning your route. After recent heavy rain, many pits are full of water.

Dog restrictions

Dogs allowed on courses, but must be on a lead - landowner request. Please clean up after your dog.


Enquiries, first aid and download in assembly.

Yvette Baker Trophy and Shield (YBT/S) Competitions

This qualifying round for the inter-club Yvette Baker Trophy and Shield will be run in accordance with British Orienteering’s Competition Rules.

Entry to this qualifying round is not limited to clubs within the South East Orienteering Association (SEOA); it is open to all clubs that want to participate.

The Yvette Baker Shield competition is for smaller clubs. British Orienteering determine which clubs are eligible to take part in the Shield competition and publish this information on their website. The Trophy and Shield competitions are treated as entirely separate competitions taking place at the same event.

All competitors must be Juniors in age classes M/W18 or under. Eligibility for each course is defined within the Competition Rules document. Anyone competing on a course for which they are not eligible will be disqualified.

The courses used for both Trophy and Shield are Yellow, Orange, Light Green and Green. Men and women are scored separately on each of the 4 courses, giving 8 classes in total. Competitors from the same club on the same course must start at least 4 minutes apart.

For the Shield Competition, each club counts its 5 highest scorers from across all 8 classes to produce its total points (subject to certain maximum limits). For the Trophy Competition, each club counts its 9 highest scores from across all 8 classes to produce its total points (subject to certain maximum limits).

Any club team that wants to compete in the Yvette Baker Trophy or Shield competitions for juniors at this event must contact the event organiser via before midnight on the 3rd March to register their intention to participate (and give contact details of the team manager).

Gravetye Manor was built in 1598. Today it is an award winning hotel and Michelin starred restaurant surrounded by one of the most beautiful gardens in England set in the middle of a 750 acre estate. In 1884, the estate became the home of the great gardener William Robinson (1838 -1935) who laid out the garden we see today, the surrounding woodland, and also built the famous, and unique, oval walled garden. Robinson was the champion of ‘wild gardening’, a concept more popular than ever today. His legacy is fiercely protected by renowned head gardener Tom Coward who in turn works closely with executive chef George Blogg in providing the very best of seasonal food for the restaurant. The gardens can be visited by booking a tour and the estate, with views of the manor, is criss-crossed by public footpaths

Kingscote Vineyard also borders the estate and is well worth visiting - after your run.

Our thanks go to the William Robinson Gravetye Charity and Balcombe Estate for allowing us to run on the Gravetye Estate.
