Matt Brammeier has become the first rider to win the National Road Race Championships three years in a row.
The 27-year-old finished ahead of Nicolas Roche and Philip Lavery in Clonmel.
Brammeier, along with 2009 winner Roche, 21-year-old Lavery and track specialist Martyn Irvine, had gone clear, and stayed clear from the halfway stage.
Irvine was dropped at the last lap and at the finish, Brammeier, who rides for the Omega Pharma-Quickstep team, had five seconds over Roche of the Ag2r-La Mondiale team, with Lavery, riding for Node4-Giordana, coming in third, nine seconds behind the winner.
Irvine had to settle for fourth place while it was nearly six minutes before the next rider, Sean Downey, came in.
His An Post-Sean Kelly team-mate, Connor McConvey, came home sixth.
Paudie O’Brien, Damien Shaw, Ronan McLaughlin, and Adam Armstrong completed the top ten.
Armstrong’s Eurocycle squad took the team award.
With overall victory going to Brammeier, it remains to be seen if the Olympic Council of Ireland will uphold his appeal to be included in the 2012 team for the London Olympics.
Cycling Ireland has already refused his request.
The Irish team for the Road Race in London is Nicolas Roche, Daniel Martin and David McCann.
Neither Martin or McCann rode in the National Championships.
