Hickman’s speed of 133.22mph was the fastest lap of practice week so far on the Gas Monkey Garage BMW, with the outright lap record holder also recording the first sub-17 minute time of 2022, completing the 37.73-mile Mountain Course in 16m 59.579s.
He was on course to increase his pace even further on the M1000RR on his second flying lap, but Hickman ran out of fuel, with his BMW stopping shortly after Signpost corner.

“It cut out at Hillberry and then again at Signpost, and that was pretty much it then. I’m a bit knackered now but the Superbike is going pretty well and I’m happy with it.”

Todd has been in sizzling form and is a real contender for the podium tomorrow.
“Honestly, I’m just loving every minute of every lap out there,” he said.
“Those two laps on the Superbike were two of the easiest laps I’ve done here and everything just flowed. I just want to do as many laps as I can and I’ve got the bikes, so there’s no excuses.”
