It's the final day of the Festival of Motorcycling 2014 - weather allowing.
The main event of the meeting, the four-lap Full Factory Winnerswear Senior MGP, has been moved again, this time to a 12.30pm start, because of strong winds on the Mountain Road.
The MGP Riders Reunion Parade will follow it.
The two have been switched around, to give the race a better chance of going ahead in what's thought to be the drier part of the morning.
Roads around the course are remaining closed, until no later than 5pm, although there is the option to close roads again this evening,from 6pm to no later than 9pm.
