Giro d'Italia The
UCI considered a potential revoking of Vacansoleil-DCM's ProTeam licence in mid-February, which would stop the team from automatically being invited to any World Tour race and be demoted to a Professional Continental team, as they were in 2010. This licence issue came to light due to continued investigations into doping regarding two of the team's riders; Mosquera and Riccò. Mosquera had tested positive for
hydroxyethyl starch at the
2010 Vuelta a España, while Riccò had been admitted to hospital earlier in February, amid allegations that he had carried out a self-administered
autologous blood transfusion at his home. (For more information on the Riccò allegations, see the
Dismissal of Riccardo Riccò section) Despite talk of a potential exclusion from the race due to these scandals, the team were included in the list of 23 teams admitted, on March 7, per UCI rules. The team's showing in the stage 1
team time trial was average, as they came home 10th of the 23 teams, 37 seconds off the winning pace set by . Božič finished near the front of the field in the Giro's first road stage, taking fifth in the mass sprint finish to the second stage, in
Parma. Hoogerland and Selvaggi made breakaway attempts on stages 7 and 8, but neither could hold a sustainable advantage until the end of each stage. Carrara moved into the top ten overall after stage 9, finishing 14th on the race's first summit finish, at
Mount Etna. Selvaggi took the team's only top-ten placing in the second half of the race by finishing eighth in a mass sprint finish on stage 12, while Carrara eventually finished the race as the team's highest placed rider in the general classification, finishing 17th overall.
Tour de France Feillu was the team's leader for the Tour, leading a youthful team into the race, with three riders – De Gendt, Poels and Ruijgh – eligible for the
young rider classification. Westra made the first breakaway of the Tour along with two other riders, while the team finished 20th of the 22 teams in the team time trial. It was not until stage 3 that the team finished highly; Feillu finished second behind 's
Tyler Farrar, with Božič also making it into the top ten, in eighth position. Hoogerland and Westra made breakaway manoeuvres on stages 4 and 6 respectively, but again could not muster a big enough advantage for a stage victory. Hoogerland did however take the lead of the mountains classification at the conclusion of the sixth stage, where Feillu had finished fourth and Marcato ninth. Feillu took another fourth place the following day on the seventh stage into
Châteauroux. Hoogerland made another break from the peloton on the ninth stage, as he was joined by five other riders who extended their lead over the field. With remaining, Hoogerland and fellow escapee
Juan Antonio Flecha of were involved in a dramatic crash; while attempting to overtake the riders, a support car from
France Télévisions sideswiped Flecha, and as a result, caused Hoogerland to crash into a barbed wire fence, and would later require 33 stitches to close gashes on his leg. Prior to the crash, Hoogerland had gained enough points on the stage to retake the lead of the mountains classification from 's
Tejay van Garderen. Flecha and Hoogerland both finished the stage and were jointly awarded the combative rider award for the day. Marcato made the breakaway on stage ten, with Feillu and Božič again making the top ten at stage end; Feillu finished fifth with Božič three places behind, in eighth place. Feillu closed the first half of the race, with sixth place on stage 11. None of the team's riders featured prominently in the early mountain stages, as it was not until stage 16 when Vacansoleil-DCM returned to the top ten of a stage result, with Marcato finishing eighth into
Gap. Božič was tenth on stage 17 and seventh on the final stage, sandwiching two top ten placings for De Gendt, who finished sixth on stage 19 to
Alpe d'Huez, and fourth on the following day's
individual time trial. At the race's conclusion, the team's highest-placed rider was Ruijgh in 21st, some 33 minutes down on race winner
Cadel Evans of .
Vuelta a España , who was second for in
2010, failed to start the 2011 race due to an ongoing investigation into a positive doping test. Although the team had
2010 runner-up Mosquera on their books, they elected not to send him – having been on the team's pre-selection list – to the race due to the ongoing investigation into his positive doping case for
hydroxyethyl starch. Instead, the team elected to place leadership upon the shoulders of Poels, who had taken second place and a stage victory in the
Tour de l'Ain, held one week before the Vuelta. but Pidgornyy was part of a successful four-man breakaway on the third stage, and although he eventually finished 15 seconds down on the eventual stage winner
Pablo Lastras (), Pidgornyy moved into fourth place in the general classification. Poels featured in the top ten of the next two stages, the sharp incline to
Sierra Nevada – finishing eighth, two places behind teammate Lagutin – and was the closest to 's
Joaquim Rodríguez on the steep finish into
Valdepeñas de Jaén. He also tried to make a late-stage move, within the final , on the eighth stage, but was unsuccessful, as he was swallowed up by the main field prior to the 20% gradient final climb to the line. Ligthart and Keizer made their way into the breakaway on stage 9, with both being dropped before the climb to
La Covatilla. Pidgornyy made it into his second breakaway of the race, as the race moved into its second half, on stage 12, but he and rider Luis Angel Maté were overhauled with just remaining. As the race began to take shape in the
Cantabrian Mountains, Poels continued his impressive Vuelta by again featuring in the top five of a stage, by taking fourth place on stage 14. Having stayed with the main group of overall contenders, Poels managed to stay with the likes of 's
Bradley Wiggins and
Chris Froome, while others such as Rodríguez and defending race winner
Vincenzo Nibali of had faded out of contention. Poels slipped out of the top ten after losing time on the finish to
Peña Cabarga, and thus tried to make a breakaway the following day, on stage 18, but was not given the freedom to break and finished with the main field. Poels ultimately finished the race 17th, but the team's best-placed rider honour went to Lagutin, who finished almost three minutes ahead in 15th place. ==Season victories==
