Directions / Parking

Parking and event registration will be located at North Hill off Windmill Street, Brill. Just head for the windmill and you’ll see signs. Please be considerate to local residents when parking. Because of the restricted parking space, please share lifts where possible.

Terrain Description

Brill is a charming hill-top village with wonderful views to look forward to, and some nice pubs for refreshments afterwards.

There are numerous contour features in this open area related to clay workings. A cattle enclosure is surrounded by an electric fence denoted as a crossable fence on the map. The cattle are Dexters and are friendly. The electric fence will be turned off for the event. You can duck under the fence at any point though there are gaps marked on the map.  There is also a goat enclosure, marked on the map as out of bounds – please do not try to enter it.

It’s a great area for beginners, because it is all open – just with lots of humps and dips so the challenge is navigating through all the contour lines. There are brambles and courses have been planned to avoid the worst of them. Full leg and arm cover are recommended. It is very muddy and slippery at the moment, please wear your grippiest footwear.

There is a pond in the competition area past by all courses. Please tell unaccompanied juniors not to go near the pond.

The Map

1:4,000, with 2m contours. Size A4. Map completely updated using LiDAR data March 2025 to ISOM 2017-2 with minor updates for the event by Mark Thompson.

No loose control descriptions.

Courses

YOU MUST REPORT TO THE DOWNLOAD TENT BY 1PM LATEST AS CONTROLS WILL BE COLLECTED IN AT 1PM.

Control descriptions will be on the map only.

If you’re a runner trying orienteering for the first time, the Red course is ideal – you will probably run 5km doing it; if that is too much, then Orange might be more suitable.
For family groups, we recommend the Orange course, or Yellow if you want something shorter.
For juniors, Yellow is a good course, though juniors new to the sport should be accompanied.

Orange, Red, Light Green and Green courses cross a public road twice – the crossing will be manned and timed out. YOU CAN ONLY CROSS THE ROAD AT THE MARKED CROSSING POINT. You will be disqualified if you are caught crossing elsewhere. You’ll have a minute to cross the road each way, so do take your time. These times will not count your overall race time. There is good visibility along the road in both directions but please take care.

Course lengths are straight line distances between the control points. You can expect to run at least 20% more than the stated distances!

The THAMES VALLEY JUNIOR ORIENTEERING LEAGUE runs in conjunction with TVOC’s Saturday Series. Brill is the penultimate Junior League event of 2026. Any junior aged 18 or under who enters this event as an individual and who successfully completes a course on their own (or in a junior pair on the Yellow course only, or who is shadowed by a parent/carer on the Yellow or Orange courses only) will be automatically included in the Junior League standings. Please note that any junior who enters and participates as part of a family group, or other group, will not be eligible for the Junior League. More League details and full rules can be found at https://tvoc.org.uk/junior-league/

Start Times

Starts will be from 10.15 to 11.45am. The Start and Finish are adjacent to the car park.

IMPORTANT: Courses close at 1pm. You must report to the download tent by 1pm latest, even if you retire or have not finished. The controls will be collected from 1pm onwards

How To Enter

THERE WILL BE NO ENTRY AT THE EVENT. Entry only via SiEntries – see link at the top of this page.

We will leave entries open, in theory until the morning of the event – but note that some events fill up well before the day of the event. In this case further entries will not be possible.

There is a limit to entry numbers because of the restricted parking.

You don’t have to be a member of an orienteering club to enter this event.

Small family or other groups are welcome, but please enter only the Yellow, Orange or Red courses. You just need a single entry. Enter as a Senior (M/W 21+). You will be asked if you are entering as a group – say Yes. With your entry you will receive one map. However we recommend you have one map EACH – you can order extra maps (£1 each) when you enter.
