Boston Manor Park 27th June

On Sunday 27th June SLOW will host the first in the series of Greater London Orienteering Summer Series (GLOSS) races, straddling the West London Boroughs of Hounslow and Ealing using Boston Manor Park. Organiser Duncan is hoping that with the start and finish located less than 500m from the Piccadilly Line station of Boston Manor, many Londoners and others from further afield will turn out for this gentle return into Sunday morning orienteering.

We are offering two courses in line with GLOSS guidelines – a GLOSS course of 4km with optional extension of 2km and a yellow course of around 2km. Start between 10 and noon, although this may be extended to spread runners out if there is a large turnout.

Please continue to respect the latest Coronavirus restrictions when taking part in this event, and please be courteous to other park users when out on your course.


The start and finish are 10 minutes walk from Boston Manor tube station. Although there should be parking available on Boston Manor road itself, competitors are encouraged to travel by public transport in keeping with the ethos of the event.

There will be two courses of 4.0km (with 2.0km optional extension) and 2.0km straight-line distance respectively. These are linear courses, which means you need to find the controls in order and the fastest person to do so wins. 

We will be using SportIdent for this event for timing purposes. 

Technical details

These will be posted on or around Thursday 17th June.

All competitors take part at their own risk. If you have any questions, just ask me on .
