From my days of helping with access issues and advising Race Organisers, I should think we are all happy that an organised event takes place, manned by volunteers and run or raced for enjoyment. Whatever route the RO chooses and is permitted to use, just give the RO the support they all need. Over the last twenty years I can think of very few events where a route has not had to have some modification to accommodate issues outside of fell running. Worried about a new route? Come and do one of the FRA navigation weekends!
