AI quick summary
- The Giro is a 21-stage grand tour held in May, covering ~3,400 km across Italy. Organized by RCS Sport. La Gazzetta dello Sport (the pink sports newspaper) founded it in 1909 — the pink jersey is the color of the newspaper's pages
- Four jerseys: Maglia Rosa (GC), Maglia Ciclamino (points, cyclamen purple), Maglia Azzurra (mountains, blue), Maglia Bianca (young rider, white)
- The Giro differs from the Tour: steeper climbs (Dolomites exceed 20% pitches), more unpredictable stages, worse May weather (snow on the Stelvio), and a more open GC that rewards attacking climbers
- Iconic climbs: Stelvio (2,758m, 48 switchbacks), Gavia, Mortirolo (avg 10.5%, max 18%), Zoncolan (the hardest km in cycling — 22% avg)

The basics
The Giro d'Italia is a 21-stage grand tour held in May, covering approximately 3,400 km across Italy and occasionally neighboring countries (Slovenia, Hungary, and Denmark have hosted Grandi Partenze). Organized by RCS Sport — the same company that runs Milan-San Remo, Il Lombardia, and Strade Bianche. The race was founded in 1909 by La Gazzetta dello Sport, the pink-paged Italian sports newspaper, which is why the leader's jersey (the maglia rosa) is pink.
The Giro is the first grand tour of the season, preceding the Tour de France (July) and the Vuelta a España (August-September). Its May slot means the weather is volatile — snow on the high passes is a real possibility, and the mountain stages are often contested in cold and rain.

The four jerseys
The Giro's four classification jerseys, plus the team classification.
| Jersey | Color | Classification | How it's won |
|---|---|---|---|
| Maglia Rosa | Pink | General Classification (GC) | Lowest cumulative time across all stages — the overall winner |
| Maglia Ciclamino | Cyclamen (purple) | Points | Most points from stage finishes and intermediate sprints (since 2017; replaced the red jersey) |
| Maglia Azzurra | Blue | Mountains (KoM) | Most points on categorized climbs, weighted by difficulty |
| Maglia Bianca | White | Young rider | Best GC rider aged under 25 |
| Team classification | No jersey (yellow helmets/numbers historically) | Team | Lowest cumulative time of each team's best 3 riders per stage |

How the Giro differs from the Tour
The Giro climbs are steeper. The Dolomites have pitches exceeding 20% (the Zoncolan averages 22% for its hardest kilometer), whereas the Tour's mountains are generally longer and steadier. The steep gradients favor lighter, punchier climbers over the powerful time-trialists who dominate the Tour.
The stages are more unpredictable. The Tour has devolved into controlled bunch sprints and team-dominated mountain trains; the Giro's shorter, steeper, more technical stages produce breakaway wins and GC swings that the Tour's structure discourages. The Giro is the more watchable race for fans who like chaos.
The weather in May is worse. Snow on the Stelvio and the Gavia has canceled stages; cold and rain are routine. This adds a layer of attrition that the July Tour, in European summer, doesn't face.
The GC is typically more open. Because the Giro is the first grand tour of the season and many top riders save themselves for the Tour, the Giro's start list is often a tier below the Tour's — which means the race is more competitive and the pink jersey changes shoulders more often. The Giro rewards attacking riders; the Tour rewards controlled strategy.

Iconic climbs
Passo dello Stelvio (2,758 m): the second-highest paved mountain pass in Europe, with 48 switchbacks on the southern (Trento) side. The Cima Coppi prize is awarded to the first rider over the Giro's highest point each year — often the Stelvio.
Passo del Gavia (2,618 m): narrow, exposed, and often snowed in during May. Andy Hampsten's legendary 1988 ride over the Gavia in a blizzard — where he became the first (and still only) North American Giro winner — is the climb's defining moment.
Mortirolo: average gradient 10.5%, maximum 18%, 12.4 km of sustained pain. The climb is a regular Giro fixture and a genuine GC separator.
Monte Zoncolan: the hardest kilometer in professional cycling. The Ovario side averages 22% for 1 km, with pitches reaching 27%. The Zoncolan doesn't decide who wins the Giro — it decides who loses it.

Legendary Giro moments
Coppi vs Bartali (1940s-50s): the rivalry that defined Italian cycling. Fausto Coppi and Gino Bartali split the country between their factions; their battles in the Giro are the race's foundational legend.
Andy Hampsten over the Gavia (1988): the American attacked in a blizzard, took the pink jersey, and became the first North American to win a grand tour. The image of Hampsten, face caked in mud and ice, is one of cycling's most iconic.
Marco Pantani on the Oropa (1999): dropped his chain, lost 30 seconds chasing back, then attacked alone up the Oropa to win the stage. The Pirate at his most theatrical.
Tom Dumoulin's toilet break on the Stelvio (2017): the Dutchman stopped to answer nature's call on a freezing descent, lost the pink jersey briefly, then won the final time trial to take the overall. The most famous bathroom break in cycling history.

How to follow it
The Giro is broadcast on GCN+/Eurosport (Europe and much of the world) and on FloBikes (North America). Highlights and stage recaps are available on the Giro's official YouTube channel and on Cyclingnews. For results and classification data, ProCyclingStats is the reference.
The stages to watch: the high-mountain summit finishes (Stelvio, Zoncolan, Mortirolo) are where the GC is decided; the individual time trial(s) are where the specialists bank time; the final weekend is typically a mountain stage and a TT that settles the podium. If you can only watch a few stages, watch the final-week mountain stages — that's when the maglia rosa is won and lost.
