Igor Arrieta won stage 5 of the 2026 Giro d’Italia after one of the most chaotic finales of the race so far, catching and passing Afonso Eulálio in the final 100 metres in Potenza. Eulálio had looked set to take both the stage and the maglia rosa after a huge ride from the breakaway, but had to settle for second on the day while still doing enough to move into the overall lead.
The Men’s Giro d’Italia 2026 full route guide had already marked this as an awkward and potentially important transition day. It was long at 203km, it was wet, and it carried enough climbing to tempt stage hunters while also posing real questions for the GC teams. In the end, it delivered all of that. A large and dangerous breakaway forced Lidl-Trek into a difficult chase, the weather kept making the roads treacherous, and the final hour turned into a contest of climbing, descending and survival.
Rain, attacks and a break that took time to form
The stage began in miserable conditions. Riders rolled out from Praia a Mare already dressed for a hard day, with rain capes on, extra layers packed and little sense that anyone was going to enjoy the opening hours. Even before the race properly began, it looked like one of those Giro days where the weather would shape everything.
That proved accurate almost immediately. The attacks started as soon as the flag dropped, but nothing stuck at first. Riders kept trying to go clear, the peloton kept reacting, and the race took a long time to settle into any kind of pattern. Thomas Silva was one of the early attackers, eager to respond after losing the maglia rosa the previous day. Einer Rubio was active too, while Victor Campenaerts and Gianmarco Garofoli also forced the race forward.
Only after around 40km did the move that mattered begin to take shape. The front group eventually became a strong and awkward 13-rider break featuring Afonso Eulálio, Manuele Tarozzi, Lorenzo Milesi, Einer Rubio, Ben Turner, Gianmarco Garofoli, Victor Campenaerts, Igor Arrieta, Jhonatan Narvaez, Martin Tjøtta, Christian Scaroni, Thomas Silva and Darren Rafferty.
That was a problem for Lidl-Trek. Ciccone had taken pink in Cosenza on stage 4, but Eulálio was only 1 minute and 11 seconds down on GC. Silva was there too, while Rubio and Rafferty were close enough overall to keep the pressure on. This was never going to be a harmless move.

Once the break was established, the tactical battle became obvious. Giulio Ciccone had the maglia rosa, but Lidl-Trek could not simply control the whole stage on their own and still expect to have support later when the major climb arrived. Even so, they had little choice but to ride, and Amanuel Ghebreigzabhier spent a huge amount of time on the front trying to keep the move within range.
Behind the break, the conditions stayed grim. Riders kept adding and shedding layers. The rain came and went, the roads never looked fully trustworthy, and there was a constant sense that a single mistake on a descent could decide someone’s day. The break itself was not always smooth either. There were moments when the riders worked well together in a double pace line, then others when the rhythm faltered because some clearly doubted they could survive the major climb later on.
Still, the move stayed clear and stayed dangerous. Ciccone appeared uncomfortable in the cold. Vingegaard stayed well placed with several team-mates around him. The stage never looked calm, even in the stretches where nothing dramatic was happening.
Arrieta attacks before the main climb
The decisive racing began before the Montagna Grande di Viggiano properly bit. With around 55km to go, Igor Arrieta attacked from the break to force a selection. It was a sharp move at exactly the right time. The escape was too big, too mixed and too unstable to survive intact all the way to Potenza, and Arrieta recognised that before anyone else.
He quickly opened a gap on the rest while behind him the bunch, now much reduced, continued to grind away in the wet. As the climbing intensified, the break split under pressure and only the strongest riders could think about bridging across.
Afonso Eulálio was the rider who managed it. He rode across to Arrieta and the pair reached the top of the Montagna Grande di Viggiano together, while the rest of the break scattered behind them and the peloton came apart in the chase.
Ciccone loses pink as the GC group shrinks
At this point the stage became a race within a race. Up front, Arrieta and Eulálio were fighting for the stage. Behind them, Ciccone and Lidl-Trek were trying to limit the damage to the maglia rosa. The trouble for them was simple enough. Eulálio had started the day close enough on GC that the gap no longer needed to be huge.
As the climb and the wet descent took their toll, the bunch was cut to around 30 riders. Ghebreigzabhier eventually cracked after a long shift on the front. Derek Gee-West was too far back to offer much help. Ciccone was left trying to survive rather than control.
By then, the jersey had effectively gone. At one stage the maglia rosa group was around 5 minutes down on the leaders. Even when it later stabilised a little, there was no realistic route back into pink for Ciccone. The stage 4 result and narrow overall lead had always left him vulnerable on exactly this sort of day, and stage 5 exposed that vulnerability completely.
Crashes change the finish again and again
The final 10km were pure Giro chaos.
First Arrieta crashed on a wet hairpin descent. He slid out at speed, got back up, changed bike and set off again, but for a moment it looked as though his stage chance had gone with him. Eulálio pressed on alone and seemed to have the stage and maglia rosa moving together in his favour.
Then Eulálio crashed too.
He slipped out on the same treacherous roads and suddenly the race changed once more. Arrieta caught back up, and the two leaders were together again, both bloodied, both carrying the marks of the road, both still convinced they could win.
Even that was not the end of the drama. Inside the final 3km, Arrieta nearly ruined his own comeback by taking a corner badly, braking too late and riding into the tape that closed off the road on the left. He was furious and had to chase once again as Eulálio pressed on.
At that stage it looked like the Portuguese rider had finally done enough. He had worked more of the two, he had the maglia rosa to chase, and Arrieta was visibly wary on the wet roads after his crash. The finish, however, still had one more twist.

Arrieta snatches victory in the final 100 metres
The run into Potenza was not straightforward. There was still a short climb to deal with, then a descent into town and finally an uphill drag to the line. Eulálio kept pushing, fully aware that both the stage and pink were in his grasp if he could hold Arrieta off.
Arrieta, though, kept him close enough to matter. He never quite let the gap go. Through the final kilometre he could still see him, and once the road rose again he committed to one last effort.
It was enough.
In the final 100 metres, Arrieta caught and passed Eulálio to take the biggest win of his career. It was his first WorldTour victory and only the second win of his career overall. After everything that had happened, the celebration was raw and emotional. He crossed the line in tears.
Eulálio had to settle for second on the stage, but he still got the prize that mattered most to the overall race. The maglia rosa was his.
The peloton arrives long after the stage is decided
Behind the leading pair, the stage was spread out all over the road. The remaining chasers from the original break came in across several minutes, and the peloton was still racing long after Arrieta had finished celebrating.
The GC group eventually came home 7 minutes and 14 seconds down on Arrieta, confirming that Ciccone’s time in pink was over. The GC riders, still cold and soaked, had little appetite to hang around at the finish. It had been one of those long Giro days that empties everyone.
For UAE Team Emirates-XRG, it meant a second straight stage win after Narvaez’s success in Cosenza. For Arrieta, it was the breakthrough result his ride deserved. For Eulálio, it was still a remarkable day, one that leaves him in pink and gives Bahrain Victorious control of the race heading towards a very different set of questions in the mountains.
Stage 5 to Potenza had been billed as awkward and dangerous. It ended up being even more dramatic than that.
