GLOSS – Gunnersbury Park, Sunday 17th July

Entries now open at SiEntries

On Sunday 17th July SLOW will host the fourth in the series of Greater London Orienteering Summer Series (GLOSS) races, in Gunnersbury Park.

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 an orienteering club.


We are offering two courses in line with GLOSS guidelines – a GLOSS course (light green standard) of 3.6km with optional extension of 1.3km, and a yellow course of 1.8km.

Yellow course:

Mixture of tarmac paths and compacted gravel paths. Three (c. 20m each) sections on short grass – these are dry and compacted currently. This includes a section to registration/start and finish. There are also small (1-2m) distances on dry mud areas to reach some controls from the main path. 

The majority of controls will be placed around 1m above ground level. 

The course can be completed without using steps (there are steps in the park, but not on the optimal route!).

GLOSS course (and extension)

The course uses a mixture of surfaces. Markers will be placed either slightly (1m) above ground level or on ground. Participants will need to cover areas of steps and uneven land/undergrowth – full leg cover is recommended.
