The race started in
Rotterdam with a 9 km prologue won by
Fabian Cancellara.
Sylvain Chavanel claimed the lead from Cancellara on Stage 2, after a massive crash which involved many riders, most notably
Andy Schleck, a contender for overall victory, and
Alessandro Petacchi. The riders in the peloton chose to wait for the fallen riders. However, on the cobbles of Stage 3, Cancellara retook the overall lead as Chavanel struggled.
Fränk Schleck had to retire from the race, having sustained a
collarbone fracture on a crash which delayed many of the riders in the peloton, including Contador and Armstrong who were hopeful of finishing high in the general classification. A number of their rivals, including Andy Schleck,
Cadel Evans and
Ryder Hesjedal, were ahead of the crash and so were able to gain a time advantage.
Green jersey contender
Thor Hushovd won the stage and took the lead in the Points classification as
Geraint Thomas, who was riding in his second Tour, finished 2nd and took the
white jersey from
Tony Martin, who had been wearing it since the Prologue. On Stage 7 Chavanel again raced away from the field to take his second stage win and
maillot jaune of the 2010 edition of the race, whilst Andy Schleck took the young riders' classification lead from Thomas. Evans took the yellow jersey from Chavanel the following day on Stage 8, and in turn lost the lead to Schleck on Stage 9 following a rest day. followed by other favourites on
stage 9 In Stage 11, Petacchi took the green jersey from Hushovd;
Mark Cavendish won the stage, but his leadout rider,
Mark Renshaw, was disqualified from the Tour after headbutting
Julian Dean while leading out his teammate. On
Stage 15 Schleck was race leader and pressing the pace over the day's final climb of Port de Bales when he threw his
chain. Contador and Denis Menchov immediately moved to the front and attacked, pressing the advantage over the crest of the climb and all the way back down into Bagneres-de-Luchon. They were aided by Sammy Sanchez and two others making a group of five riders, all looking to gain time. Schleck chased hard, but had no other riders to help bridge the gap. By stage's end, he had lost the yellow jersey and 39 seconds to Contador. Contador, who now had an eight-second lead in the race, met with a mixed reception as he received the yellow jersey on the podium at the end of the stage. Contador said that he did not know that Schleck had technical trouble, and that he had already launched an attack by then, but review of the race shows that he was chasing an attack by Schleck, that he nearly struck Schleck as he moved past him, and that he looked back repeatedly on the climb while Schleck struggled to close down the gap. Hours later, he apologised for the incident. Although he was criticised by
Sean Kelly and a number of riders both past and current, Cervélo team owner Gerard Vroomen commented: "Contador just gained a great chance to win, but he lost the chance to win greatly." This same stage saw
Anthony Charteau take the lead in the
King of the Mountains competition from fellow Frenchman
Jérôme Pineau. in the start of the
stage 17 in
Pau The
17th stage was considered this Tour's
queen stage. The first-category
Col de Marie-Blanque and Col du Soulor climbs preceded a grueling summit finish atop of the
Hors Catégorie Col de Tourmalet, the second ascent of the Tourmalet of this year's Tour. The stage turned into a battle between
Andy Schleck and
Alberto Contador. The tour's top two riders separated themselves from the field on the final climb. Schleck launched numerous attacks upon Contador in the final 15 kilometres, but was unable to separate from him. Contador coolly stayed on Schleck's wheel, and attacked as well once, but was pulled back by Schleck. Schleck went on to take the stage over Contador, who seemed happy to follow Schleck across the line while holding a seemingly unassailable lead in the GC. Meanwhile,
Anthony Charteau confirmed his hold on the Polka-dot Jersey, as the Tour completed its final categorised climbs. On stage 18 Petacchi took the green jersey from Hushovd for the final time. The points classification was hotly contested between these two riders and the jersey changed hands a half dozen times between them throughout the race.
Stage 19 was the final time trial. It was widely expected that Contador would increase his lead over Schleck, who in the past had struggled in this discipline, but the initial going surprised all as Schleck set a high pace that Contador had difficulty matching. By the first time check Schleck had picked up six seconds, cutting Contador's overall lead to just two seconds on the road. By the second time check Contador had recovered his losses and extended his lead over Schleck by six seconds. Over the final third of the course Contador extended his advantage, gaining an additional twenty-five seconds on his rival for an overall gain of thirty-one seconds for the stage. Fabian Cancellara, the
Olympic and
World Time Trial Champion, won the stage by seventeen seconds over runner-up
Tony Martin. In addition
Denis Menchov was able to overtake
Samuel Sánchez for third place overall, while
Ryder Hesjedal was able to move in front of
Joaquim Rodríguez for the seventh place slot in the GC. Contador's first-place lead increased to 39 seconds, essentially guaranteeing him the victory. The final stage was won by Cavendish, who became the first winner of consecutive
Champs-Élysées stages. The
Manx sprinter won five stages, more than any other rider in 2010 Tour, taking his career tally to
15 stage wins. Original tour winner
Alberto Contador finished surrounded by his Astana teammates. This was his third
Tour de France in three consecutive entries, after having won it in
2007 and
2009. Schleck finished in second place for the second year in a row (later to receive the victory after Contador's positive test and subsequent ban) and Menchov completed the podium in third place. Petacchi won the
Green jersey. His second-place finish in the final stage gave him enough points to finish just above Cavendish and Hushovd. France's Charteau won the
Polka dot jersey.
Doping In September 2010, Contador revealed that a urine sample he had given on 21 July, a rest day in the 2010 Tour de France, had contained traces of
clenbuterol. He has stated, due to the number of other tests he passed and that only a tiny amount of the substance was detected in the one he failed, that food contamination was to blame. The UCI issued a statement reporting that the concentration was 50
picograms per millilitre, and that this was 1/40 the minimum standards of detection capability required by
WADA, and that further scientific investigation would be required. In late January 2011, the Spanish Cycling Federation proposed a one-year ban, but it subsequently accepted Contador's appeal and cleared him of all charges. The UCI and the
World Anti-Doping Agency each referred the decision independently to the
Court of Arbitration for Sport in March 2011, but Contador remained free to ride until their ruling was made. The hearing was delayed until after the
2011 Tour de France at Contador's request and then deferred to November 2011. On 6 February 2012, the CAS stripped Contador of the 2010 title, making Andy Schleck the winner. Armstrong's finish in the 2010 Tour—originally 23rd; 22nd at the time of its stripping—was also stripped. In January 2013, Armstrong admitted to doping in an interview with
Oprah Winfrey. Although he admitted to have doped in his seven wins, he denied doping in the
2009 and 2010 Tours. Regardless, Armstrong was stripped of his finishes in those two Tours as well, because his blood values indicated that he doped.
USADA's report stated that "The likelihood of Armstrong's blood values from the 2009 and 2010 Tours de France occurring naturally is less than one in a million". On 10 July 2014, a UCI press release detailing various athlete sanctions specified that Menchov had been banned (for a period of two years) until 9 April 2015 due to adverse biological passport findings. Due to this, he has been disqualified from the 2009, 2010 and 2012 Tours de France. In May 2011, newspaper ''
l'Equipe'' published a list of cyclists and an index that indicated the suspicion for doping use. ==Classification leadership and minor prizes==
