Anyone using the shared path between Leith & Crewe Toll today - beware of the Granton Road - Crewe Toll section which is strewn with glass. Obviously the local wildlife have been out in force.... Not even my Schwalbe Marathon Pluses could withstand the effects of the 20m glass carpet and I suffered an unexpected deflation event. I actually thought I'd holed both tyres at once, but I think the rear's OK. Nice 20 minute inner-tube change and attempt to inflate the tyre with my crappy little pump in the freezing cold - my protective glasses froze over as I left them sitting on some metalwork as I did the repair !! I've reported it to Clarence who'll hopefully send in the sweepers soon. If it's still there on the way home, I'm getting off and walking that section or I might just get on the road and go down Ferry Road to Leith.
