Yes, serious updating of the Event Management Plan is required.
New entry:
HAZARDS!!! Man-eating bog close to Waun Fach Summit
RISK REDUCTION STRATEGY....10 foot (2.7metre) Barbed wire fence demarcating hazardous zone, 12 fully trained bog snorkelers on standby, 2x10 ton mobile cranes and 3xballoon-tyred landrovers parked on 50 tons of hardcore safety surface adjacent to path at GR.......

Phew, this race org don't get any easier!!

On a less silly note, the trackers did show the route we took but sometimes took 45 minutes to update their position. So they cannot be relied upon for live position update at all times. But they will tell us where a missing runner has gone to....eventually.
Have been rethinking the race control and have decided to add a safety refuge extension at the CP by the north end of the reservoir...its connected by track to SR3 so is easy to service. We can check runners off the start list as they come back down from the most exposed part of the route. Simples.
