It's nearly 3 months old, but today was the first time I'd ridden it.
Very nice two metre path from near the end of Daiches Brae to Brunstane Mill.

So almost continuous tarmac (and mostly downhill) from the Engine Shed to the Forth including a fair chunk alongside the Brunstane Burn that forms the border between Edinburgh and East Lothian when it reaches Eastfield.
Looking back up the path - left goes to Newhailes House.
Where the BB joins the Forth.
