We have just marked the start, finish and once check point but have suggested a course based on previous experience. You will be skinning against the flow of traffic until you reach the top of the access chairlift but should then be away from the crowds if you stay below the Eagles Rest Cafe to reach the far side of the Etive Glades run. The snow conditions on the day will dictate the descent route you take but will probably be the Spring run the the upper part.
The suggested route for the lower part of the descent will either be direct of a more gradual line - racers discretion.
