I have read a good few posts about walking with purpose. The weather has been so cold here - I am local, live less than an hour from Aberdeen (know the City well) and my brother in law lives in Torry. They could have been walking briskly simply because of the cold and adverse conditions. Also, it is possible to go from the path to South Esplanade West. There is also more than one boat club on the river there, Aberdeen Boat Club, Aberdeen University and RGC University Boat Clubs are also there.
