OMM Lite

OMM Lite is a map-navigation event held in Grasmere on 5th–6th June 2027. Competitors are given a map that shows the location and point value of checkpoints; the organiser has placed 30 checkpoints around the valley. Each checkpoint is marked with a two-letter code and a control box that records a visit.

Entrants can choose to compete for one day or two days. There are two course options with time limits: Long Course with time limits of Saturday 7 hours and Sunday 5 hours, and Short Course with time limits of Saturday 5 hours and Sunday 4 hours. Participants may enter as individuals or as teams of two or three; teams must stay within talking distance of each other at all times.

Maps used are Harveys 1:25000. At the start each day competitors receive a new map showing all available checkpoints and their scores. Timing uses SPORTident chips and a timing tag is used at each control box to register visits; a manual record of the control letters is accepted if the box fails.

The event sets minimum kit requirements for safety. Required items include a taped seams waterproof jacket and trousers, suitable mountain clothing and footwear, a warm layer, hat and gloves, a whistle, compass, pen or pencil, the supplied map, basic first aid, emergency food, water carrying capability and a fully charged mobile phone. Organisers may carry out random kit checks and can disqualify competitors who lack necessary kit.

Entry prices are listed per person and include timing chips, live tracking, event photographs, bespoke OMM Lite maps and a hot meal after the event. Visit the organization's website for the most recent information.
