Into Stirling to collect the truck (with its new cylinder head) via Doune, Thornhill, and the A811 nr Kippen. Strong headwind all the way to Thornhill, crosswind to the A811, then a great tailwind into Stirling.
Dodgy vertebra in neck niggling to start, completely seized up afterwards; if it's not one thing...!
Bertha moving along well with her new rear wheel.
