Map updated in 2021 to ISOM 2017-2 by Julian Birkinshaw

No loose control descriptions.

Start Times

THERE WILL BE NO ENTRY ON THE DAY. You must pre-enter, via SIEntries - see link at the top of this page.

Starts will be from 10.15 to 11.45am. The Start and Finish are 500m North of the carpark within Hodgemoor Woods

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.


Please note the climb when choosing a course.
YELLOW: 2.0km, 10 controls, ca 45m climb. Suitable for juniors with some experience or for supervised newcomers, and for family groups.
ORANGE: 3.4km, 12 controls, ca 60m climb. Suitable for adult beginners and experienced juniors.
RED: 5.4km (expect to run more than 6 km), 15 controls, ca 75m climb. Longer, but less challenging navigationally. Ideal for runners new to orienteering. You still need to be able to read a map, but it is more like an unmarked trail race.
LIGHT GREEN: 3.7km, 11 controls, ca 60m climb. More challenging; for improvers and those with a bit of experience. Most controls away from paths and more route choices.
GREEN: 4.9km, 13 controls, ca 110m climb. Most challenging. Only for those with experience at orienteering. More navigation.


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.

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. 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/
