  • The route starts and finishes at the Law Society of Ireland in Blackhall Place, Dublin 7 and takes an anti-clockwise loop North up the R135 (Old Ashbourne Road) to the “Nine Milestone Roundabout”.
  • The 100 km route then heads North through Ashbourne, leaving the N2 to take the back roads up to Rathfeigh, then West towards Tara and down the R147 to Dunshaughlin. The route then takes a loop around the R154 (towards Trim) before cutting across to the R156 and returning via Dunboyne, cutting to the South of Blanchardstown, through the Phoenix Park and along the Quays back to Blackhall Place.
