Please collect your number from registration on arrival – the number on each of your maps matches this.  Please wear on your front so we can help you get the right map at each exchange.


We are not allocating times, so please turn up and go when you choose (this is in the final details.) The busiest course is the green which has 59 pre-entries.


South London Orienteers very much look forward to welcoming you to Richmond Park on Sunday. We thank the Royal Parks for granting us access to the park for the “OK Nuts Trophy Races.” Richmond Park is a National Nature Reserve, London’s largest Site of Special Scientific Interest, a European Special Area of Conservation and the largest of London’s Royal Parks.

We are pleased to have had 213 pre-entries, including some newcomers, with 122 of those choosing one or other of the mass start races. In line with the usual practice in the sport we now provide “final details”, which aims to tell you everything you need to know to fully enjoy the day. But of course if after reading you do have any questions please get in touch, for example we are here on Facebook.

Runners on the Full Blood course will be pleased to see that the distance is more than a half marathon.

All – please be courteous to other park users, and to the park. The summary message  is “tread lightly – leave nothing behind, take nothing away.”  In particular, for runners on the Full and Half Blood using gel packs – please do not drop the packaging, but rather carry it to the next map exchange / the finish. Thanks.

Holmwood Common 18th February

South London Orienteers welcome you to orienteering races on February 18th, on Holmwood Common and Scamells Grove, three miles south of Dorking.

Final Details (uploaded 10th February)

This is a British Orienteering Regional (Level C) Event. There is a choice of eight individual colour-coded courses: Brown, Blue, Green, Short Green, Light Green, Orange, Yellow and White.

We have a new map, at 1:7500, to the ISOM2017 standard. The woods are mostly natural, and on gentle slopes. There is a good path network, lots of vegetation changes, and many streams, ditches and gullies. Longer courses visit an area of runnable forest new to orienteering. Courses are planned to avoid the worst of the brambles and undergrowth.

NO DOGS please – the assembly and car park is on a working cattle farm.

“OK Nuts” Races, Richmond Park, 21st January

The Final Details are linked to this later post.

SLOW’s annual “OK Nuts” Trophy Races will be on January 21st in Richmond Park, London. The title comes from the name of one of the early orienteering clubs in the UK.

There will be three mass start loop races (20km, 15km, 10km) and shorter colour-coded individual start races. The mass start races are called “Blood Races” in a reference to the annual ‘Blodslitet’ races of Fredrikstad Skiklubb in Norway, which use this format. “Blood” in the name is a metaphor for the increased physical challenge, compared to a typical orienteering race.

SLOW Club Championships

All club members are welcome to the club championships on Saturday December 2nd. These are a separate part of the Southern Navigators event at Wisley that morning. We have a run, and we have a picnic, comparing our runs if we want, and we have a prizegiving.

Please see Paul Couldridge’s Facebook Event in the SLOW members group for details.

The nearest station is West Byfleet (trains from Waterloo take 30 minutes) approximately 4km from the event centre at the Royal Horticultural Society Wisley Garden. Or do use the Facebook Group to seek a lift.

Please reply by Sunday 26th November at the latest.

Wisley Common

Wisley Common is a nature reserve of lowland heath on acidic sandy soil designated SSSI and managed by the Surrey Wildlife Trust. It lies between Surrey’s main two interior rivers, the Wey and the Mole. These days it is more easily identified by proximity to M25 Junction 10, where the M25 London Orbital Motorway crosses the six lane A3 London-Portsmouth road.
The terrain is heathery heath and natural woodland with many paths and some stretches of metalled road. There are many ditches, some slopes, and some areas where going is more difficult. Some of the ground will be quite wet if it has rained, and in places there may be some shallow water to run through.

Area History

The A3 was one of the principal routes in Britain in the days of the stage coach, as it linked the capital and the main base of the Royal Navy. Elsewhere “the Portsmouth Road’s” route is much changed but it has passed Bolder Mere, as it does today, for many centuries. In the later nineteenth century it was part of the most popular bicycle outing in southern England, the ride out from London to the old coaching inns of Ripley.
The very heavily used M25 is a relative newcomer. Long in the planning, the sections here were among the later sections completed in the 1980’s.
The Royal Horticultural Society were gifted Wisley in 1904 by a wealthy Quaker, Sir Thomas Hanbury. Its 240 acres of gardens are the second most visited paid entry garden in the United Kingdom, with a million visits a year. The gardens and laboratory employ 90 people.

Autumn Series – Final Race Looms

Updated version: because ranking points for Bucklebury have become available.

On Sunday, at Wormley Woods near Broxbourne,  the final race of the SLOW Autumn Series happens.

The last four Sundays have been the other races in the series, at Epsom Downs, Ambersham Common, Highland Water and Bucklebury Common. We all decided that we would use BOF ranking points to compare runners, and then use a 100-99-98-etc scale to award points, with best 3 of 5 to count. All just in time for the AGM.

Unfortunately, last Sunday’s Berkshire Orienteers’ Bucklebury has not had the best of luck, although the woods were lovely and the weather was good if not so warm. As of Wednesday evening the results are not uploaded to BOF and ranking points are not available. The whole point of having a  series is to have the light-hearted comparisons, and maybe create a little bit extra to the race for those going on Sunday.

So, by calling on the rule that:

if anything unforseen happens, we will do our best to do sensible things,

we have used relative speed in mins/km (adjusted for height gain) to enable scoring of last Sunday.

Update: (Thursday morning) Results were uploaded about midnight last night and ranking points calculated overnight. There is little change to scores based on estimation (which have been left in the attached pdf for interest) – Simon and Dorte have swapped the 94 and 93 scores.

We are setup with some interest for the last race, with several folk likely to add a third run, or to improve an earlier one. At the top of the table with Paul’s fast run at Bucklebury not counting because of a missing control (of which there were quite a few across all runners)  Yordan leads overall. But Paul and Ollie are pre-entered to get their third scoring runs, and have a fair chance (Paul‘s is better than Ollie‘s.) Dorte looks a safe bet for leading woman, and Olin has probably done similarly in the junior comparison.  In the body of the table plenty of places can be won, and you can spot several “local rivalries”.

Autumn Series 4 – Bucklebury

Photo of Don gliding through the forest, by David Jukes  (who long ago when a member of London OK made a great map of Hampstead Heath.)

It was nice and challenging Chilterns forest on a fairly crisp day, the heavy rain having stopped earlier in the morning. Thanks to Berkshire Orienteers for putting it on.

This was nominated as the fourth race in the SLOW Autumn series of five races.

After a delay because of problems with some controls, results are now published.  Paul Couldridge and Olin Davies are down as having missed a control. Given the evident problems with some controls I think they can be counted as even more unlucky than usual. Also, Paul did the second fastest time on the longest course and would have wrapped up the Autumn Series had his run counted.  Olin‘s run on the blue is noteworthy as a long run for an M14. And his dad Keith did blue too, so they will have been able to talk through the course and compare splits anyway (Olin was quicker, but I guess that doesn’t count unless you get all the checkpoints.)

That left 16 SLOW runners completing courses that will get ranking points.

Brown: Paul Nixon, Dmitry Adamskiy, Simon Moss, Kwun Him Himmy Lau.

Blue: Yordan Kolev, Paul Street, Don McKerrow, Andy Robinson, Chris Evans, Di Leakey, Sarah Brown, Fiona Tam, Keith Davies, Heather Walton.

Green: Dorte Torpe Hansen, Chris Robinson.

We cannot score the Autumn Series yet, because that depends on Ranking Points and they are not yet available.

There are currently 15 SLOW entries for the final race in the Autumn Series, at Wormley Woods in Chigwell territory, on Sunday.
