The 100th anniversary Senior TT will take centre stage at the Isle of Man TT in 2027 as part of a revised nine-race schedule, with the blue riband race moving back to its traditional Friday slot after major changes were confirmed by the organisers.

The RST Superbike race will also revert to the opening Saturday, while only one Superstock race will be held instead of two.

Next year’s TT races will begin with qualifying from Monday, May 31 to Friday, June 4, with a new race programme running from Saturday, June 5 to Saturday, June 12.

The schedule features revised race formats, more contingency flexibility throughout race week and a special celebration of motorcycles that have shaped the history of the iconic Senior TT.

The opening four-lap Monster Energy Supersport race will take place on Sunday, June 5, providing a greater opportunity to run the race within the shortest scheduled road-closure window of any race day.

Following a contingency day on Monday, racing will resume on Tuesday with a standalone four-lap RL360 Superstock TT Race followed by the opening Motul Sidecar TT Race.

Wednesday’s schedule includes the second Monster Energy Supersport TT and the opening Carole Nash Sportbike TT Race, both over four laps, before an additional contingency day on Thursday.

The 100th edition of the Milwaukee Senior TT will take place over six laps on Friday, June 11 with Saturday providing a contingency opportunity should the race be affected by weather or other delays.

The second Carole Nash Sportbike TT Race will take place on Saturday, June 12 along with the second Motul Sidecar TT Race.

This year’s programme was heavily impacted by adverse weather on the island, with both Superstock races cancelled and the second Sportbike race also called off.

The showpiece Senior TT was declared a result after the first lap following a red flag, with poor weather preventing the race from being rerun. In 2025, the Senior TT was cancelled for only the second time in the history of the race because of high winds on the Mountain.

Both Sidecar races were axed on safety grounds in 2026 following incidents in qualifying, but organisers say the class is poised to return next year ‘subject to the successful completion of the ongoing technical, operational and governance work surrounding the class’.

A two-race format will be retained, with each Sidecar race running over two laps of the 37.73-mile Mountain Course.

Paul Phillips, Head of Motorsport, Isle of Man TT Races said: “The schedule introduced in 2023 achieved a number of important objectives for the TT. It created stronger opening and closing weekends, provided more racing across the week and gave visitors much greater choice around how and when they came to the Island.

“Across the four TT events in which it has operated, the schedule has helped us attract more fans and deliver greater economic benefit to the Island. Those gains remain central to the 2027 programme, but four years of experience have also provided valuable evidence about where the schedule can now be refined.

“For 2027, we believe the right balance is nine substantial and clearly defined races. Moving from two Superstock races to one allows us to give the remaining Superstock race and both Sportbike races greater substance, create more recovery time within the programme and provide better protection around the Superbike and Senior TTs.”

Phillips said the changes represented an “evolution rather than a return to the programme that existed before 2023”.

He added: “It retains the stronger two-weekend structure while giving each race day a clear purpose. Superbike provides an immediate headline race on the opening Saturday, while placing the 100th Senior on Friday allows us to build the day around that historic occasion and retain Saturday as a genuine contingency opportunity.

“We also want the 100th Senior to be about much more than the race itself. It gives us an opportunity to celebrate the riders, motorcycles and extraordinary performances that have made it the most important race at the TT.”
