;21 August 2009 - Powerscourt to Waterford, 196 km This stage began at the Ritz-Carlton hotel in Enniskerry and immediately the peloton set to climbing, with a third-category climb coming after 7 km. The course continued to be hilly after that, marked by the first-category Mount Leinster climb coming about halfway into the stage. There were two more categorized climbs and a few smaller rises later on. Many ultimately unsuccessful breakaway attempts occurred in the stage's first hour, including defending mountains champion Matt Wilson topping the first category three climb in first position. The first escapee to stay away for any amount of time was MTN's Jay Thomson, who was the first over Mount Leinster and Coppanagh, putting him second in the King of the Mountains standings at the end of the day. Thomson badly bonked on the day's last climb, and wound up being passed by escapees from the main peloton. First to pass him by was Philip Lavery of the Irish National Team, and then came the rest of the 23-man group, one that included numerous big names such as Lance Armstrong, Stuart O'Grady, and defending Tour of Ireland champion Marco Pinotti. With Mark Cavendish stuck in the peloton 2' 12" behind the leaders, the stage win was wide open. After numerous attacks and counterattacks Russell Downing was the man to time his sprint just right, getting to the line a second ahead of seven other riders. Armstrong, O'Grady, and twelve others finished 16 seconds back. Time bonuses won at the finish line and in intermediate sprints meant the first General Classification was not the same as the Stage 1 result.

Stage 2
;22 August 2009 - Clonmel to Killarney, 196 km The first An Post sprint of the day was at Ardfinnan after 9km. The climbing again began early on this stage, with a second-category climb occurring after 27.5 km. After the descent and one short uncategorized hill, the course was flat until another second-category climb, Musheramore, at the 135 km mark. Immediately after the descent from Musheramore was Curragh, a climb that was shorter, but steeper, and was categorized higher at first-category. Mark Cassidy of An Post–Sean Kelly sprinted out of the bunch immediately after the neutralized section of this stage. He was joined by Rabobank's Dennis Van Winden, and they were together through the three sprints and the first two climbs on the stage. The peloton was quite willing to let these two get a huge advantage, and their time gap over the main field ballooned to over ten minutes. It was between the third sprint and the last climb that Van Winden attacked and shed Cassidy, who hit the wall and wound up finishing over nine minutes back of the peloton at the finish. Van Winden was caught shortly after the descent from Curragh, but he managed to finish with the peloton, despite having been in a breakaway for 174 of the stage's 196 kilometers. Van Winden won each of the day's climbs and in so doing poised to challenge Matt Wilson for the King of the Mountains championship, but Wilson took maximum points from the peloton on each climb and finished the day with a 4-point lead. The mass sprint finish took place, with Mark Cavendish easily outclassing the other sprinters in the field. Each of the 23 riders who made the selective break in Stage 1 finished with the peloton, meaning race leader Russell Downing had 22 riders within 26 seconds of him going into the decisive third stage. It was on a stage much like this in the 2008 Tour of Ireland that Downing lost his race lead, but he expressed confidence after the stage that he would be able to keep it this year, as the finishing circuit in Cork for the 2009 race is shorter than it was in 2008. Team Columbia-HTC made it clear that their focus for Stage 3 would not be Cavendish, who freely admitted the circuit was probably too tough for him, but for defending Tour of Ireland champion Marco Pinotti, 11 seconds back of Downing.

Stage 3
;23 August 2009 - Bantry to Cork, 185 km This course defines undulation, with more than a dozen rises in elevation, though only three are categorized. The peloton will take three laps of a finishing circuit in Cork, taking three passes over the first-category St. Patrick's Hill. Uniquely, only the second and third passes over the climb will count toward the climbers' prize, while the first pass is an intermediate sprint. As was expected, the third stage broke the field up more than either of the first two had. The largest group to cross the line together was the eight riders classified third through tenth, those with the same time as Matti Breschel. Many riders crossed the line alone, and two members of Team Joker Bianchi finished almost 21 minutes behind the stage winner. 57 riders also withdrew during the stage, including the two the event had most used to promote itself, Lance Armstrong and Mark Cavendish. There was no significant breakaway on the day. Rather, the exact opposite seemed to take place, as riders little by little dropped off the pace of the leading group and either abandoned the race or finished many minutes behind the leaders. The last two together were Lars Petter Nordhaug and race leader Russell Downing. Since Downing had the event overall sewn up, Nordhaug took the stage. Downing's performance on this stage marked a significant improvement over the Cork stage from the 2008 Tour, where he, as race leader, was dropped and conceded the final yellow jersey to Marco Pinotti. On this day, it was Pinotti who was dropped before the finish, finding himself in the first chase group 33 seconds behind Nordhaug and Downing. The climbs were taken by riders who had not yet scored any significant points in that classification, so Matt Wilson was able to come away with his second consecutive King of the Mountains win.
