Please note, now on SUNDAY

Directions / Parking

Parking by kind permission of the Earth Trust. Space is very limited, so please park as close together as practical. Once this area is full, there is additional parking at the public car park further along the road.

Terrain Description

Generally open pasture land, with small wooded areas, streams and interesting contour features from the large Clumps (hills) that give the area its name. Expect to be climbing these hills on your courses!

Start Times

Registration open from 10am to 11.30am.
Start a course any time from 10.15am to 11.45am.
Everyone must finish and report back to download by 1pm, even if you haven't finished your course.

Parents are advised to accompany children across the road from the car park to the Registration and Start areas


WHITE ~1-1.5km
RED ~4.5km

If you're a runner getting into orienteering, the Orange and Red courses are ideal. For family groups, we recommend the Orange course, or Yellow/Red if you want something shorter/longer. For juniors, White and Yellow are good courses. No courses cross any public roads.

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

How To Enter

You can register in advance, or just enter on the day.

We recommend you register in advance. This reserves you a map, and avoids you having to fill in a paper entry form. It's really easy, and there is no commitment. Just click on the Reserve a Map link below, and fill in your details, then pay when you arrive. Maps are reserved until 11:15.
NOTE Remember we are now using SI Air. If you have your own SI Air card, then when you use the reserve map facility please go into My Runners (link is on the top line) and add the SI Air numbers (if any) for your saved runners.

If you want to enter on the day, then just come to the registration tents.

Whether you have pre-registered or are entering on the day, come to the registration tents located by the car park in the Brookes campus. There are three tents (1 is form-filling, 2 is paying, 3 is to collect your SI Air timing chip). If you have pre-registered, you can go straight to tent 2; otherwise go to tent 1.
