It's the final day of the 2015 Festival of Motorcycling
The 2015 Festival of Motorcycling reaches its grand finale today (Friday 4).
The Senior Manx Grand Prix sets off from the Grandstand at lunchtime, with just short of 100 riders on the grid for the big race.
Diehard fans are taking up taking up their favourite viewing spots around the Mountain Course, ahead of roads closing at 9.30am.
They're hoping today's racing will see some fierce competition for MGP honours, before the festival fortnight comes to a close.
The SuperTwin/Lightweight begins at 10.15am, with the showcase Senior Manx Grand Prix starting 15 minutes earlier than planned at 1pm.
