John Mcguinness Opens With 133.925mph Lap at Isle of Man TT

john mcguinness watched Dean Harrison set the fastest ever opening-day lap at the Isle of Man TT on Tuesday night, with a 133.925mph effort on the 37.73-mile Mountain Course. Harrison was the only rider to go above 130mph at the first attempt after Monday's opening session was cancelled, and the lap immediately reset the pace for the 2026 event.

Dean Harrison Sets the Pace

Harrison went on to post two 133mph laps, and his opening run stood as the quickest first-day effort ever recorded on the course. Michael Dunlop was next best with a 130.341mph lap, while Nathan Harrison completed the trio of Superbike riders to break the 130mph barrier on Tuesday night.

That list left the front of the Superbike field tightly defined at the sharp end. Peter Hickman was seventh in the class while still recovering from injuries sustained 12 months ago in a practice crash, a detail that kept his result in sharper focus than the raw placing alone.

Superstock, Supersport, Sportsbike

Josh Brookes topped the Superstock class with the night's fourth and final 130mph lap. Michael Dunlop also set the pace in Supersport on his factory-backed Ducati V2 Panigale, and Paul Jordan was quickest in the newly renamed Sportsbike class.

Those class leaders gave Tuesday night a clear pattern: the fastest outright lap came from Harrison, but different riders owned the other headline categories. The numbers also showed how quickly the session settled after the cancelled Monday opener, with the front-runners pushing straight into 130mph territory once the roads opened.

Brandish Sidecar Crash

The sidecar session brought the sharpest interruption. Red flags came out halfway through the class's first timed session after Maria Costello and Shaun Parker came off at Brandish on their second attempt.

Both riders were taken to Noble's hospital, with Costello transferred by helicopter and Parker by ambulance. They were reported as conscious as talking, while Costello reported head injuries and Parker reported leg and arm injuries.

Qualifying was due to resume on Wednesday with roads closing at 12.30pm, and Thursday was set aside as a rest day. After Harrison's 133.925mph benchmark and the sidecar crash that cut short part of the night, the next session now carries the job of proving whether the leading pace was a one-off or the start of a sustained run.
