Specifically the bit from Perth to Kingussie.
I can get to Perth on fairly pleasant roads, but the obvious bit from there northwards is the A9, which looks less pleasant to ride up.
I believe there is a bike path option following the A9? Has anyone used this?
Does it follow the A9 pretty closely or does it go miles out of the way?
How well surfaced is it? The whole journey is going to be 150+ miles for me so would like to do it on a fast carbon road bike with tiny tyres, fine if the track is decent tarmac, less good if it’s badly maintained gravel. The other option is a singlespeed gravel bike, OK for the gravelly track but really slow everywhere else and it would take ages and be really hard work. A multitude of compatibility problems means there can be no frankenbikes, the bigger tyres won’t fit the road bike, the gears won’t fit the gravel bike, etc.
Pitlochry to Pitagowen looks like it has a viable alternative route, but not sure about the rest.
Cheers
