Out of the 198 riders that started this edition of the Giro d'Italia, a total of 140 riders made it to the finish in Milan. The 22 teams that took part in the race were:
Route and stages
The route for the 2002 Giro d'Italia was unveiled by race director Carmine Castellano on 17 November 2001 in Milan. It contained three time trial events, all of which were individual. In the stages containing categorized climbs, four had summit finishes: stage 5, to Limone Piemonte; stage 11, to Campitello Matese; stage 13, to San Giacomo; and stage 17, to Passo Coe. The organizers chose to include two rest days. When compared to the previous year's race, the race was shorter, contained one more rest day, and one more individual time trial. In addition, this race had an opening prologue like the year before.
Classification Leadership
In the 2002 Giro d'Italia, five different jerseys were awarded. For the general classification, calculated by adding each cyclist's finishing times on each stage, and allowing time bonuses for the first three finishers on mass-start stages, the leader received a pink jersey. This classification is considered the most important of the Giro d'Italia, and the winner is considered the winner of the Giro. Additionally, there was a points classification, which awarded a mauve jersey. In the points classification, cyclists got points for finishing in the top 15 in a stage. The stage win awarded 25 points, second place awarded 20 points, third 16, fourth 14, fifth 12, sixth 10, and one point fewer per place down the line, to a single point for 15th. In addition, points could be won in intermediate sprints. There was also a mountains classification, which awarded a green jersey. In the mountains classifications, points were won by reaching the top of a mountain before other cyclists. Each climb was categorized as either first, second, or third category, with more points available for the higher-categorized climbs. The highest point in the Giro, which in 2002 was the Passo Pordoi, afforded more points than the other first-category climbs. The fourth jersey represented the intergiro classification, marked by a blue jersey. The calculation for the intergiro is similar to that of the general classification, in each stage there is a midway point that the riders pass through a point and where their time is stopped. As the race goes on, their times compiled and the person with the lowest time is the leader of the intergiro classification and wears the blue jersey. There were also two classifications for teams. The first was the Trofeo Fast Team. In this classification, the times of the best three cyclists per team on each stage were added; the leading team was the team with the lowest total time. The Trofeo Super Team was a team points classification, with the top 20 placed riders on each stage earning points for their team. The rows in the following table correspond to the jerseys awarded after that stage was run.
Other less well-known classifications, whose leaders did not receive a special jersey, were awarded during the Giro. Other awards included the Combativity classification, which was a compilation of points gained for position on crossing intermediate sprints, mountain passes and stage finishes. Italian Massimo Strazzer won the Most Combative classification. The Azzurri d'Italia classification was based on finishing order, but points were awarded only to the top three finishers in each stage. The Azzurri d'Italia classification was won by Mario Cipollini. The Trofeo Fuga Piaggio classification rewarded riders who took part in a breakaway at the head of the field, each rider in an escape of ten or fewer riders getting one point for each kilometre that the group stayed clear. The classification was won by Mariano Piccoli. Teams were given penalty points for minor technical infringements. was the most successful in avoiding penalties after not being penalized during the race, and so won the Fair Play classification.
