After the mid-stage climb on Tuesday, the Giro d'Italia ramps up another notch on Wednesday's stage 5, which should see a big breakaway battle and maybe even some GC skirmishes.
With 4,100 metres of climbing across the rolling hills of the Basilicata region, and a distance that exceeds the 200-kilometre mark, it's a grueling day for everyone involved.
The route sets off from the coast, climbs into the Pollino National Park and up Prestieri, a steady 12km ascent before tackling the hardest climb of the opening stages, the Montagna Grande di Viggiano after 154km.
The steep 6.6-kilometre haul, which has an average gradient of 9.1% and a maximum gradient of 15% in the closing kilometre, tops out just under 50 kilometres from the finish, and is followed by rolling terrain before the descent to Potenza.
The Potenza finale, with its slightly uphill finish, is similar to 2022, when Koen Bouwman won from a breakaway.
With only two categorised climbs, it's somewhat surprising that the total elevation gain exceeds the 4000-metre mark, but this is a long day on rugged terrain with plenty of draggy climbing that will sap the legs by the finish.
Those stats, combined with the severity of the Montagna Grande di Viggiano climb, have the potential to make this a GC day. Jonas Vingegaard has already shown he's in the mood to attack and the two-time Tour de France winner certainly has the ability to light up the race on those slopes. Likewise, plenty of contenders might find themselves in trouble.

However, what might quell any GC fireworks is the distance of the summit from the finish line – almost 50km. Although there's plenty of descending, it would take a bold move to go there, and there is space for groups behind to mount a chase.
What is perhaps likelier is a first breakaway success of this Giro d'Italia. All the teams will be sensing an opportunity and there should be a big battle to get into the day's escape. With the first climb coming after just 16km, we're in for a fast and furious start to the stage, with a volley of attacks on that climb.
A break might only finally go in the middle section of the route, and then it remains to be seen how strong it is, which teams try and control the race in the peloton, and if the break can stay clear over that key Montagna Grande di Viggiano climb to contest the stage honours.
New race leader Giulio Ciccone (Lidl-Trek) faces a tough first day in defense of his pink jersey, while Egan Bernal (Netcompany-Ineos) will need to bounce back after being dropped on an even easier mid-race climb on stage 4.
