The Astana team did not include 2008 race champion Alberto Contador, who chose not to defend his championship, but did include Lance Armstrong, who had recently returned from retirement.
Though his appearance was put in doubt after he crashed out of stage 1 of the Vuelta a Castilla y León and broke his collarbone, Armstrong announced on 16 April that he would start the Giro despite undergoing surgery for his injury.
Silence–Lotto star Cadel Evans was originally announced to be taking part in the Giro, but he publicly announced shortly afterward that he would not ride it, and accused RCS Sport (the organizers of the race) of using his name to promote the event.
Contador and Evans both chose to focus on the Tour de France later in the season.

Many riders were named as contenders, including Ivan Basso, Levi Leipheimer, Armstrong, Damiano Cunego, Carlos Sastre, Gilberto Simoni, Danilo Di Luca, Marzio Bruseghin, and Denis Menchov.
Before his collarbone injury, Armstrong was considered an overall favorite, and it was also noted that three time trials, including the insertion of an unusually long time trial mid-race, might favor him.
Pre-race analysis noted that Armstrong, when on his best form, would be a rider very likely to gain from having such a long race against the clock included in the Giro.

Former winner Stefano Garzelli named Leipheimer as the favorite, as did some American media outlets.
Armstrong considered Basso to be the favorite when speaking about the Giro in December 2008.
Other news outlets also referred to Basso as the pre-race favorite.

Only a small number of stages were expected to end in a sprint, barring a successful breakaway.
Sprinters in the event included Mark Cavendish, Alessandro Petacchi, Allan Davis, Filippo Pozzato, Robert Hunter, Robert Förster, Tyler Farrar, Juan José Haedo, and Oscar Gatto.
