The 18 UCI WorldTeams are automatically invited to the race. In addition, four Professional Continental teams obtained a wildcard, bringing the number of teams to 22.[4]
There were three previous winners among the participating cyclists: Alejandro Valverde (2009), Fabio Aru (2015) and Nairo Quintana (2016). Valverde (Movistar Team) and Thomas De Gendt (Lotto-Soudal) also attempted to defend their points and mountain classification titles.[citation needed]
The Vuelta a España has four individual classifications, for which jerseys were awarded daily to the leading rider, as well as a team competition. The primary classification is the general classification, which is calculated by adding each rider's finishing times on each stage. Time bonuses were awarded at the end of every stage apart from the team time trial (stage 1) and individual time trial (stage 10). The rider with the lowest cumulative time is the leader of the general classification, and wears the red jersey. The leader of the general classification at the end of the race is considered the overall winner of the Vuelta a España.[10]
The second classification is the points classification. Riders receive points for finishing among the highest placed in a stage finish, or in intermediate sprints during the stages. The points available for each stage finish are determined by the stage's type. The leader is identified by a green jersey.[10]
The next classification is the mountains classification. Points are awarded to the riders that reach the summit of the most difficult climbs first. The climbs are categorized, in order of increasing difficulty, third-, second-, and first- and special-category. The leader wears white jersey with blue polka dots.[10]
The final of the individual classifications is the young rider classification, which is calculated by adding each rider's finishing times on each stage for each rider born on or after 1 January 1994. The rider with the lowest cumulative time is the leader of the young rider classification, and wears the white jersey.[10]
There is also the team classification. After each stage, the times of the three highest finishers of each team are added together. The victory is awarded to the team with the lowest cumulative time at the end of the event.[10]
In addition, there is one individual award: the combativity award. This award is given after each stage (excluding the team time trial and individual time trial) to the rider "who displayed the most generous effort and best sporting spirit." The daily winner wears a green number bib the following stage. At the end of the Vuelta, a jury decides the top three riders for the “Most Combative Rider of
La Vuelta”, with a public vote deciding the victor.[10]
