Ciao ragazzi! Welcome to live coverage of the 102th edition of the Giro d'Italia. We're in Bologna for the opening time trial - a 8km race against the clock with a sting in the tail in the form of a savagely steep climb up to the Santuario di San Luca.

Today's top 10.

“I’m super happy,” Roglic said after his victory was confirmed. “I’ve been waiting now for three hours but it’s a really nice feeling. I didn’t have much of a tactic except to go through the course as fast as possible.” Asked whether he could emulate Gianni Bugno, who led the 1990 Giro d’Italia from start to finish, 29-year-old Roglic remained coy. “We’ll see how it goes,” he said. “The most important things is that we’re wearing it in Verona at the end. But it’s a good start and I’m looking forward to the next three weeks.”

So, it's victory and the pink jersey for Roglic, with Simon Yates second at 19 seconds and Vincenzo Nibali third at 23 seconds. Miguel Angel Lopez and Tom Dumoulin complete the top five at 28 seconds.

Niv and Puccio come home well down to confirm that Primoz Roglic (Jumbo-Visma) has won this opening stage.

It's not good enough for the win... but it's second place for Simon Yates. He comes home 19 seconds down and leapfrogs Vincenzo Nibali.

Roglic looks concerned as he watches Yates approach the closing moments. But I think he'll be ok...

Under the archway goes Yates as he hits the S-bend and the steepest section of this climb. He's out of the saddle on the long, straight ramp, giving it his all. Just after the final-kilometre marker, Yates passes his minute-man, Fernando Gaviria. That's a good sign, but then again, Roglic caught two of his...

Yates is 18 seconds down on Roglic at the intermediate check, down in 33rd place. But was he checking his effort on the flat so that he can really attack this climb? Time will tell.

Guy Niv (Israel Cycling Academy) and Salvatore Puccio (Team Ineos) are now on course - so that's everyone now. The clouds are gathering and it's much darker, but it looks like the rain will hold off for Yates.

The crowds cheer as Simon Yates gets his race under way. He won three stages last year and wore the pink jersey for 13 days before his spectacular collapse on the day Chris Froome rode into the lead. What can he do today?

Meanwhile, Roglic is limbering up and stretching outside the winner's enclosure. He's been waiting for over two hours now - time to thank his fan club from Slovenia, who have gathered near the finish and are flying numerous flags. We'll soon see his trademark telemark celebration on the podium as he dons the first maglia rosa of this race. Unless...

Simon Yates has finished his warm up and has headed to the start ramp. He's off in less than five minutes.

Adam Hansen (Lotto Soudal) and Antonio Nibali, Vincenzo's brother at Bahrain Merida, are next to go. There's been a huge lull in this time trial since all the favourites went around two hours earlier. If it wasn't for Yates, we'd have all packed up and gone home. But he's the man who could, in theory, do something today - although you expect Roglic pretty much has this in his pocket.

Elia Viviani, the Italian national road champion, gets his TT under way. Tomorrow he'll be in his Italian jersey but for now he's in regulation Deceuninck-QuickStep kit, having stripped off his top layer before leaving. The 30-year-old will be battling it out with the likes of Fernando Gaviria, Caleb Ewan, Arnaud Demare and Pascal Ackermann in the sprints this year.

Team Ineos have their exciting Colombian climber Ivan Sosa on the climb now. He's making his Grand Tour debut today and it's been a baptism of fire for the 22-year-old, who comes come in 91st place 1:56 down on Roglic. He's good on the uphills but he can't time trial for toffee. Still, he should prove one part of an exciting trident alongside Sivakov and Geoghegan Hart for Ineos.

Mollema was the biggest name to change his bike today - none of the other GC riders tried. He added: "It was the right decision for me to change. I am currently in the top 10 so I think that is a good result for me. I am quite happy with my TT."

Jumbo-Visma have two riders in the current top ten in Roglic (1st) and De Plus (7th). Bahrain-Merida, too, have two in Nibali (2nd) and Caruso (9th), ditto Astana with Lopez (3rd) and Bilbao (10th).

Big man Conor Dunne, the tallest rider in the peloton, rolls down the ramp for Israel Cycling Academy. The Irishman has opted for a regular roadbike out there today, so he's going all-in for the climb rather than the flat section before.
