Manx Grand Prix and Classic TT organisers have been forced to massively rejig the rest of the festival with poor weather forecast for the end of next week.

As a result the remainder programme, which should have run through to Friday, will now take place over the next four days.

Three races are now scheduled for Saturday, two for Sunday afternoon, four for Monday and finally one on Tuesday.

A statement from the organisers released on Friday evening said: ‘Following detailed consideration of the latest weather forecast, the Race Organiser has issued a substantially revised schedule for the remainder of the 2026 Manx Grand Prix and Classic TT Races.

‘The long-range forecast currently indicates that conditions are expected to deteriorate significantly from Wednesday, with wet weather, significant rainfall, and wind expected until at least the end of the scheduled event period on Friday.

‘The revised programme has therefore been developed to make the best use of the more favourable conditions currently forecast between Saturday and Tuesday, providing the strongest available opportunity to complete the remaining Manx Grand Prix and Classic TT races.

‘The new schedule includes racing on Saturday, Sunday, Monday and Tuesday, with the Historic Junior Race brought forward to Saturday, the Formula One Race and combined Lightweight and Ultra Lightweight Races brought forward to Sunday, and the Historic Senior Race and Junior 600 Race brought forward to Monday.

‘The 2026 Classic TT is now scheduled to conclude on Tuesday 25th, with the Senior Classic TT followed by the 1996 Rewind Parade, Classic Sidecar Parade, and John McGuinness 30th Anniversary parade.

‘The revised schedule reflects the latest weather modelling and the race organisers commitment to delivering the scheduled programme of events in full when conditions are safe enough to do so.

‘The forecast will continue to be monitored closely and, should there be a material improvement in the forecast for later in the week, the race organiser may make further adaptations and use additional available periods.

‘Every session remains subject to weather, course conditions and the race organiser’s established safety and operational requirements. Further changes may therefore be made where necessary.

‘Should the racing programme be completed by Tuesday and forecast conditions prevent further activity on the Mountain Course, the Classic TT will endeavour to deliver an expanded programme of off-track activity throughout the remainder of the week.

‘Centred around the Mercury Club, home of the John McGuinness MBE Exhibition, this programme may include rider and team appearances, chat shows, live podcasts, interviews and other Classic TT activities. Further details will be confirmed as arrangements are finalised.

‘The organisers recognise the additional demands these changes will place on competitors, teams, marshals, officials, residents, businesses and visitors, and thank everyone affected for their continued flexibility, cooperation and support.’

The Manx Grand Prix’s Sportbike and Supersport races are still scheduled for Saturday, with the Junior and Senior races down to be run as planned on Monday.

Roads close on Saturday morning at 9.30am, with a Classic TT qualifying lap at 10.15am.

The three-lap Sportbike MGP takes place at 11.45am, with the Supersport MGP at 2.45pm.

The day’s action will conclude with the two-lap Historic Junior Classic TT at 4.45pm.
