26x1.75 Pasela Tourguard are great tyres, lightweight, comfortable and roll well.
I used them for a 2500 mile fully loaded tour of New Zealand seven years ago, on tarmac and gravel roads, no problems, no punctures.
I don't use them on my Sherpa because I have gone up to 2 inch tyres so now use Schwalbe Marathon Supremes, but sometimes consider going back to Paselas.
They are still recommended by Thorn in their brochures I think.
A good choice for a lejog trip in my view.
