Schedule said practice was cancelled due to weather yesterday. Apparently they did go out. https://manxgrandprix.co.uk/latest/page/statement-gary-vines/ RIP Today's session is currently stopped as well.
Just got back from the Manx. Harrisons 916 was a work of art, and fast. Michael Dunlop is on top form looking very fit. But the bikes were the stars at the Manx GP with the spectators all rolling around in museum pieces, lots of Vincents, Nortons, Ducatis in the parking lot. I however, got to do 14 laps of the mountain course in a plain Yamaha 700 triple with luggage, still fun in regular traffic. there is effectively no speed limit on the island. Great event.
