After bad weather forced an early end to Monday's action - with only the speed-controlled laps for Newcomers completed - a revised Isle of Man TT schedule sees Free Practice moved to this evening, in place of what should have been Qualifying 1.
The Tuesday evening schedule - featuring all five classes, starting with the Sidecars - is as follows:
18:00 - All Roads closed
18:30 - Sidecar (Untimed)
19:10 - Supersport, Supertwin (Untimed)
20:15 - Superbike, Superstock (Untimed)
Tomorrow's action will see the first timed sessions of the week with Qualifying 1 for the Superbike, Superstock and Supersport classes beginning at 18:30 followed by the Sidecars at 20:10.
Qualifying 2 will be held on Thursday and Qualifying 3 on Friday.
The chequered flag is out.
