steady run 3:20:00 
With E (well behind him for most of the run tbh) Glenshee, Glas Maol, Tolmount (E added Tom Buidhe), Fafernie, Carn a Claise, Broad Cairn, Glen Muick. Lots of other walkers out and about and Loch Muick track was busy... Got to car park earlier than expected so wandered along road a while waiting for S to pick us up.
Felt reasonable for much of the run, kept to my own pace and avoided trying to stay with E. Tough along Loch Muick at the end but track in good shape which made it more pleasant.
Last did this route in about 1988 or so - went over Lochnagar that time plus the Sagairts. Plus skied much of it in 2000/2001 on a glorious winter day.
