GLOSS 2017: London’s Summer Series returns!

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.

Northala Fields Park Race Results

Results from the Northala Fields Park Race, the second in this year’s London Park Race 2017 Series, have now been published.

Organiser’s Comments

Thanks to everyone who came to the Crown at Northolt for the second London Park Race of the 2017 series. It was a nice sunny evening and I hope that everyone had a nice time out there – despite some nettles and some impressive straight leg efforts that I hadn’t even expected through green terrain!
It was great that comments were generally positive about the SportIdent air punching system. Obviously this was a first time for a number of people and it did seem to go smoothly on this occasion but it’s nice to see people giving something new a try and thanks to Gordon Parker for helping me get this set up.
Don and Mat were very able helpers on the laptops this evening and Ed Nicholas of AROS and British Orienteering also came along to help with starts so thanks to those guys too. And of course Angus and Ollie for general support with the Park Race series as a whole.

This was the second time we’ve used Northala Fields and I hope we can come back there again in a couple of years. Thanks to the Crown and the events team at Ealing Council for helping us put on this event and look forward to seeing you all for the rest of the series.

– Duncan Grassie.

Wimbledon Street-O & Series Results

The ninth and final Street-O of the 2016-17 season was held in lovely spring weather on Wimbledon Common, organised by Jane Harries (recently returned from the Marathon Des Sables!). Almost 100 runners took part in the final race which brings the total for the series to well over 400 different individual participants.

The Race Results are now available as well as the Final Series Results for 2016-17. Congratulations to series winners Matthew Schepisi and Katrin Harding, who came a very impressive third overall.

It’s now over to Park Races until September when the 2017-18 street-o series will start again. I am looking for volunteer organisers, it’s a fun and easy job with lots of support provided so if you’re interested please get in touch on .

Southeast Middle Distance 2017 Results

The 2017 Southeast Middle Distance championships were run on Wimbledon Common with a brand new map and on a lovely day for orienteering. Results are below.

Planner’s Comments

Many thanks for coming to one of the more challenging areas in London!

I was very happy to be able to plan the very first event on the new map by Tom Edelsten, the map which has way more white bits now due to the recent clearing work on the common. Hope that you appreciated the improved runnability of Wimbledon! Having said that, there were also enough areas with Wimbledon trademark brambles and nettles. So the plan was to keep the more grotty parts in the middle of the courses to offer change of speed and conditions and hope that people forget about the brambly bit by the time they finish. Judging by the post-race comments that seemed to work reasonably well.

Special thanks to David Dawson (controller) and Andy Robinson (organiser), who made some crucial suggestions in the planning process (like scrapping the rough SW corner where some courses might have wondered otherwise) and all the of SLOW volunteers for running the event so smoothly!
Dmitry Adamskiy

Organiser’s Comments

A big thank you to all you competitors is top of my agenda. Not just for supporting the event, but especially for thinking about how you would get there. In the end we didn’t turn any cars away and had perhaps as many as two places to spare!

Thank you also for your understanding of the SIAC operation. Only one runner complained about having to “dib” his SIAC when he wanted to “waft”, and he realised the error of his ways at the end. I think we are all working our way up the learning curve with this one.

Thank you also to the 31 volunteers who made it all happen. The main ones there were Dmitry as planner, trying to give you a decent balance of the nice forest and the rough stuff, David Dawson as controller, and Gordon being in charge of all things technical. I think he’s working his way up the learning curve better than most of us who are just following. And don’t forget Tom Edelsten as mapper for his work over the winter – I believe you all appreciated his efforts.

Property left behind was a door key (!!) with an elephant on the key ring, and a very new looking control description holder.

Unclaimed medals will be at the Long Distance Championships on 14th May, and if not claimed then will be returned to South-East stocks. Those who hadn’t claimed one or didn’t have a clubmate who took it your behalf were

  • Silver: Izumi Magee
  • Bronze: William Chandler, Heather Findlay, Dorte Torpe Hansen, Anne Power, Colin Dutkiewicz

Well done to all those who won a medal.

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.
