Part way through the test, cars had to climb a tiny road known as the Corkscrew, one of the narrowest and tightest series of hairpin bends anywhere climbing the mountain alongside Loch Ness.
Legend has it that it was made by locals hurrying to escape from the monster.
Even with a 20mph target speed, it was flat out and many lost time, especially the big Rolls-Royce Silver Cloud and Phantom VI, which struggled to get 'round the hairpins. Wolseley Hornet Special, to Jayne Wignall and Fred Bent's Sunbeam Tiger. As far as we know, we're still in the lead at the end of Day Two, but so much can change in a week-long event. We have already lost our speedometer, though thankfully the accurate mileometer on our Halda Speedpilot is still operating. Our closest class rival, Jan van Geen in a very fast TR3A, lost his speedometer and Haldas today, but we were able to fix it for him before the Loch Ness Monster regularity.
