Not an organised event, but my (Dan S) peak training session for an ultra 3 weeks later. This will just be about covering the ground at a slow average pace - 'jeffing' it (mix of running and walking). The route is on the website linked to here. Will need to figure out where on the route to get more water/food etc.
Log into see who is doing this event.
