GLOSS 2018: London’s Summer Series

June sees the return of the Greater London Orienteering Summer Series, or GLOSS. This is a series of five accessible orienteering races held in parks and parkland around London on Sundays through late June and July.

The events are perfect for beginners and families, and there is a club competition for the prestigious London Bus trophy for those who are members of one of London’s orienteering clubs. South London Orienteers won the competition in 2016 and 2015.

There are two course options: the GLOSS course which is about 3.5 to 4.5 km (with optional extension to ~6 km) and is of moderate navigational difficulty and a ‘Yellow’ course which is about 2km with easier navigation.

Event Centre

The event centre is The Telegraph pub on Putney Heath, SW15 3TU. The pub is in the middle of the heath and there is plenty of parking available on nearby roads. Several bus routes go to “Putney Heath Green Man” which is at the north-east corner of the map and about 500m from The Telegraph.

The pub facilities will be available once it is open for business. It has an excellent range of beers and food, so make the most of the occasion! It is a popular destination on a Sunday for families and those wishing to spend their weekend in a relaxed and friendly environment, and their traditional Sunday roasts prove very popular and attract visitors from far and wide. Please book ahead if you wish to reserve a specific area or large gathering – details on the website.

Entry on the day only, and we may be able to take contactless credit card payments. Your entry fee includes a full colour map printed on waterproof paper, which you can keep as a souvenir after your run, and a printout of your race time and splits at the end of the race.

Course name Optimal route distance
Long 5.7km
Short 2.6km

Normally courses are quoted as straight line distance, but straight lines are not possible here, so the optimal route better reflects the distance that runners will cover.

The short course is suitable for juniors; under-16s on the long course must be accompanied by an adult.

The whole of the short course and the start of the long course will be in Geraldine Mary Harmsworth Park. The long course then goes on to Archbishop’s Park with some interesting urban to link the parks and to finish back near the pub. There will be two timed out major road crossings on the Long course.

The terrain will be 70% hard surfaces with the rest mown grass so shorts will be fine; high-viz clothing is recommended on the long course as 25% of it will be on streets linking the two parks.

Further Information

Competitors take part in this race at their own risk. Entries and results will be processed by computer, your entry will be taken as agreement to this. The competition is run under the rules and guidelines of, and sanctioned by, British Orienteering.

The Street-O format has clues located at various points on a map. You have 60 minutes to visit as many of these as possible, in any order, and return to the finish. This guide provides general information about street orienteering.

Don’t forget to bring a pen to write down your answers to the clues as you go around, an SI card if you have one, and a watch so that you aren’t late back! You may find a torch/head-torch and compass useful too, although many don’t take one and it should be light enough for everyone for this last event.

All competitors take part at their own risk. You MUST be over 16 to take part in this event, unless you are accompanied by a parent or guardian. This is a condition of our insurance.

Results will be available on the SLOW website shortly after the event. Check the 2017-18 series page for more information.
