The fourth race day of the 2026 Isle of Man TT was wiped out on Wednesday, with organisers cancelling all scheduled racing because of poor weather around the course and more showers forecast for the day. The event, already reduced to two completed races from five scheduled, now has even less room to fit the rest of its programme.
The cancellation landed after a week that has already been repeatedly interrupted. Saturday’s opening race day lost the three-lap Superstock TT, Sunday’s Superbike TT went the full six laps and was won by Dean Harrison, and Tuesday’s Supersport TT was cut to three laps before Michael Dunlop took his 34th TT win. That result mattered because the shortened race still counted, but it also showed how quickly the week was being compressed by the weather.
Wednesday was supposed to carry only the second Superstock race, but that too was abandoned. An organiser said there would be no scheduled racing because of poor weather conditions around the course and further showers forecast throughout the day, while the clerk of the course continued working with the Met Office to find any available racing opportunities for the rest of the event.
The pressure on the schedule is now obvious. Officials are unwilling to run more than nine racing laps in a single day, which makes the task of squeezing in the remaining races difficult, especially with Thursday originally set aside as a rest and contingency day and Saturday now the new finale for the Senior TT. Gary Thompson had already said Sunday’s final contingency day was likely to be needed for the Senior TT, and he also said the second Sportsbike TT could be run then too. One of the week’s two Superstock races is expected to be lost to the weather.
That leaves the meeting balanced on a narrow strip of good forecast and spare time. Friday is described as clear, and organisers still hope to use it, with Sunday and possibly the final weekend day, to rescue what they can from a schedule that has already been trimmed once and may need to be trimmed again.
