Having realised that the requirement is only one way ie N/W -> S/E Id say that this is as good as it gets if you want to see the sights.

- 1st 11 km is on NCN and the majority is on a nice tarmac bike path (as per Auld Alliance & WH1000)
- This does not cross the tram lines at Haymarket, it stays parallel to them all the way to Sth St Andrew Street. The "dodgy" tram line crossing at Haymarket only happens if youre heading West so thats avoided.
- The crossing of the tram lines is at an oblique angle but is easily made into a 90 degree turn by a quick "keep left to cross right" turn. As a comparison I recall crossing a railway line on the Green & Yellow 300 on Saturday that was at a less favourable angle and which had zero warning in advance.
- This is the Hollywood approach into Edinburgh as the castle and the Royal Mile skyline are revealed.
- Princes Street is open only to buses, trams, taxis and bicycles. Local buses (the maroon ones and the ones you see most frequently) have a good reputation re cyclists. I'm sure they would remind their drivers in advance if we asked them. Ditto the trams as they are sister companies.
- The bit at the bottom of The Mound (*) gets busy during the Fringe as it hosts a ticket office.
Im happy to road test this (or any variant that alwyn / wiklyboy want me to try out) next midweek and can take copious photos if that helps.
* stop sniggering at the back. yes you. And you as well.
