Riding the Villiers engined Cotton, Rob Edwards was in excellent form parting with no marks in a superb display of consistent riding. With snow still evident in the area the Blackwater Moorland crossing would see 15 retirements, as they struggled with the conditions for both man and machine. The major news of the day was the retirement of Mick Andrews on the development Ossa when the rear sprocket broke away from the hub assembly. Miller was disappointed not to have won in 1966 on the Bultaco but, as we will see, he was in a very determined mood riding with a very calculated style, making every mark he parted with count.
Tuesday: 1: Sammy Miller (Bultaco) 9; 2: Dave Rowland (BSA) 18; 3: Bill Wilkinson (Greeves) 19; 4: Rob Edwards (Cotton) 20; 5: Dennis Jones (Greeves) 21.
