Over 330 competitors are set to tackle this weekend's Manx National Two Day Trial.
Champion in 2000 Dan Thorpe is the favourite to win the solo class, with the local challenge likely to be led by Barry Kinley, Nigel Crellin and Josh Brain.
Competitors face a 37 mile tour of the south with 44 sections today (Saturday), and a further 41 sections tomorrow in the north of the Isle of Man.
It's the reverse route for the sidecars with everyone expecting a battle between the two Robins - Morewood and Luscombe - who have 22 Manx titles between them.
The likely strong challenge from Jamie Teare and Jane Birchall will not be happening as they have been forced to withdraw.
However, Juan Knight and Chris Molyneux could be up there, having won the opening round of this year's British Championship, which was also held in the Isle of Man.
