GLOSS Series 2025

The Greater London Orienteering Summer Series (‘GLOSS’) is an annual Summer competition between SLOW, HAVOC, Happy Herts, CHIG, MV and LOK, with the prize being the prestigious London Bus trophy.

There are two courses: the GLOSS course which is about 3½ to 4½ km (with optional extension to around 6 km) and is of moderate navigational difficulty, and a ‘Yellow’ course which is about 2km with easier navigation. Navigate between control points – you decide the best route to complete the course in the quickest time. Beginners welcome!

The first event in the series is on 22 June at Northa Fields, hosted by SLOW.
CHIG’s event is on 6 July at Fairlop Waters.
