I'm finding Brunswick Road pretty quiet. I've just discovered West Montgomery Street, which has A/ no cobbles and B/ closed at the end by bollards so is the perfect cycle-friendly way to cut between Hillside and Brunswick Road.
Today it was fairly quiet so after coming off the path at Roseburn I stayed on the Corstorphine Road all the way to it turning into St. Johns Road and turned off just before the shop formerly known as Happit.
It's actually takingh 40 minutes, not 35 (over-optimistic estimate).
I'll just have to learn to love all the unleashed dogs all over the NEPN at 830AM...
