Most are agreed that Judith was on a pre-planned escape route so not lost/disorientated, and John Rix apparently deliberately left the race route to seek shelter, so not lost/disorientated.
Others like Ted Pepper, Bob English and it seems Carol Matthews did inadvertently go astray.
The point remains though that many runners fail to see the potential risk of leaving the race route and don't recognise the potential safety of remaining on the route.
Inform another runner is good advice!
