I know that sections of this use the old A9, but what about those purpose built bits – are they suitable for a narrow-tyred race bike?

Some of the bits are definitely a bit rough – 28 mm probably ok 23 mm probably not IMHO.

Cheers Geoff – I was sort of assuming that, so nice to have it confirmed.

PS – I might be passing through your way….

I riode the bit from Dalwhinnie to Dalnaspeil lodge – that would have been fine I think but what Geoff says is probably right

Let me know when and I’ll put the kettle on!

Surface is typical sustrans path style for quite a lot of the bit from Dalnaspiddal to the Dalwhinnie turn-off. I’d be happy enough on 28mm touring tyres, but wouldn’t be so keen on 23mm road tyres.

There is a section of the official path which goes along the front of the Dunkeld Hilton. We ride it with the kids on fat tyred bikes, but I would think twice about riding that section even on a tourer. Luckily there is a section of the old A9 which you can use as an alternative.

Cheers. The plan is to stick to the line of the old A9 wherever possible.

have done this on my trek with 23s on. not much fun, but rideable – lacking a bit of grip on the very slight ups/downs and corners with the surface though 😮 pretty slow going, watched my average speed drop quickly!

Ah – is it used on the big sportive too?
