OMM Lite

OMM Lite is a competitive navigation and running event held at Grasmere Showground in the Lake District. Participants, either solo or in teams of two or three, navigate a series of checkpoints scattered around the Grasmere area using only a supplied map and compass—GPS devices are not allowed. The challenge is to collect as many points as possible by visiting checkpoints within a set time limit, with penalties for exceeding the time.

The event offers long and short courses over one or two days, with flexible pacing options. It combines endurance, strategy, and navigation in a scenic outdoor setting, making it a unique and engaging adventure race. Visit the organization's website for the most recent information.
