given the recent history of tragic events in fell races,i can understand why the organiser changed the route.however,i think they should have cancelled the race altogether or posponed it for Sunday (as the forcast was good for then) than put on a race that is not representative of the origional concept (if you can`t visit all the 1000m peaks ,you can`t call it the 1000m peaks race).As for giving the runners the choice,i think it should still be the organisers call,as he/she has to think about the bigger picture i.e marshalls,timekeepers,emergency services etc
