Isle of Man TT 2026: Superstock Race Cancelled, Senior TT Moved to Friday

• RL360 Superstock TT Race 1: cancelled for 2026, prize money to be divided among qualified competitors
• Milwaukee Senior TT: Friday, June 5, 4:15 PM, over four laps instead of the originally planned Saturday
• Final day on Saturday with the second Sportbike and Superstock races, with Sunday serving as a reserve day

The 2026 TT has been heavily affected by weather so far. Following several cancellations, race management has published a revised schedule designed to make the best use of available weather windows and, above all, to secure the running of the Senior TT. The latest adjustment also confirms that the first Superstock race will not be rescheduled this year. The following overview explains what has changed, which races are planned for which days, and what consequences the rescheduling has for competitors and spectators.

Why Was the 2026 TT Schedule Changed Again?

The schedule was adjusted to reflect the current weather forecast and the remaining available time slots. According to the organisers, several factors feed into the decision, including the weather forecast, the distance already covered by competitors, operational readiness, necessary road closures, and the safe conduct of racing across the entire Mountain Course.

The background to the changes is a series of cancellations. By the time the new plan was published, only two races had been completed in 2026: the Superbike race on Sunday and the first Supersport race on Tuesday. Both Sidecar races were cancelled on safety grounds, and all racing activity on Wednesday fell victim to the weather. With unsettled conditions still forecast for the coming days, the plan was restructured to allow as much of the remaining programme as possible to take place.

Which TT 2026 Race Was Cancelled?

The RL360 Superstock TT Race 1, originally scheduled to run over three laps, was cancelled. The race had most recently been provisionally slated for Thursday but is now listed as cancelled in the latest schedule and will not be rescheduled.

The organisers cite the tight remaining schedule as the reason, noting that it must accommodate multiple races, road closure times, competitor fatigue, the availability of marshals and medical personnel, and operational readiness. A further postponement would therefore jeopardise the running of other races. In line with standard procedure, the prize money in such cases is divided equally among all qualified competitors.

When Will the 2026 Senior TT Take Place?

The Milwaukee Senior TT is scheduled for Friday, June 5, at 4:15 PM and will be run over four laps. This brings the race forward from its original Saturday slot, placing it after the second Supersport race and the first Sportbike race on Friday.

The TT organisation cites the Senior TT’s particular sporting, historical, and media significance as the reason — it traditionally forms the highlight of the event. By scheduling it on Friday, the race is given the best possible opportunity to take place, rather than being exposed to a potential further weather disruption over the weekend. The fact that the Senior TT had to be cancelled the previous year also plays into the prioritisation. According to the organisers, the four-lap distance is intended to strike a balance between the race’s status, competitor fatigue, and the available time window.

What Does the Race Schedule for Friday and Saturday Look Like?

Three races are planned for Friday, with Saturday intended to conclude the event with two further races. All times and lap counts are subject to weather, track conditions, and confirmation by race management.

On Friday, June 5 — observed on the island as TT Bank Holiday — a free practice session is scheduled for 10:30 AM. This is followed by the Monster Energy Supersport TT Race 2 over three laps at 11:45 AM, the Carole Nash Sportbike TT Race 1 over two laps at 2:15 PM, and the Milwaukee Senior TT over four laps at 4:15 PM. The organisers attribute the shortened distance of the Sportbike race to the available time window and the need to balance the overall programme. On Saturday, June 6, the Carole Nash Sportbike TT Race 2 and the RL360 Superstock TT Race 2 are planned for 11:00 AM and 2:00 PM respectively, both over three laps. Should weather or track conditions prevent Saturday’s programme, both races will be moved to Sunday, with start times of 1:30 PM and 3:45 PM. The Mountain Course measures 37.73 miles (approximately 60.7 kilometres), and conditions can vary significantly from section to section, which is why decisions are often made at short notice.

What Does the Rescheduling Mean for Spectators and Tickets?

According to the organisers, refunds are not planned, as races are scheduled for both Friday and Saturday. Grandstand and hospitality tickets apply to a specific date rather than an individual race.

On both race days, roads are expected to reopen by 9:30 PM at the latest. The organisers advise that road closure times and race times remain subject to change, and recommend following only the TT’s official channels and allowing extra time for travel.

How Does Race Management Assess the Situation?

Gary Thompson MBE BEM, Clerk of the Course, refers to the disruptions that have characterised the entire event and stresses that safe conduct of racing remains the top priority. He explains that the revised programme is designed to offer “the strongest possible opportunity to complete the remaining races” while also securing the Senior TT as the event’s centrepiece.

At the same time, he acknowledges the disappointment that such disruptions cause among competitors, teams, marshals, residents, and fans, and thanks them for their patience. The cancellation of the first Superstock race and the revised order of events place this TT 2026 season in a context already marked by numerous weather-related cancellations well before the final weekend.
