Dean Harrison continued his good form in the Formula Classic Class, powering his BSA to 106.758, the fastest time of the evening and the week in that class with Gavin Lupton (100.906) the only other rider to break 100mph.

In the 500cc Class, with McGuinness experiencing problems, Olie Linsdell can take confidence from another 110+mph lap under his belt, (110.442) with Bruce Anstey on the McIntosh Racing/Mobil 1 Norton lapping at his fastest time of the week (107.927) from Palmer (106.659) riding the Richard Shelton Racing Seeley and Cameron Donald on the Ripley Land Racing Matchless also posting his fastest lap of the week with 106.040.
