Right, well that was manic. Out of nowhere a sedate stage one turned savage, with potential big implications for the general classification already.

Fernando Gaviria won in dominant fashion and will wear the yellow jersey tomorrow. Stage two could well come down to a bunch sprint as well - can Gaviria double up?

The report of stage one is building here.

And watch out for 5 live's Bespoke podcast available here later.

Mark Cavendish missed out today but you can read his guide to all the stages here.

Catch you tomorrow. Cheers!

Here are the positions of all the GC contenders, relative to the yellow jersey...

1. Fernando Gaviria 4hrs 23mins 32secs
2. Peter Sagan +4secs
3. Marcel Kittel +6secs
4. Alexander Kristoff +10secs

Fernando Gaviria is just the second Colombian to wear the yellow jersey.

The 23-year-old seized it in dominant fashion, making the most of his Quick-Step team-mates' fine work to keep him at the front by kicking clear with just over 250m to go.

Gaviria is now the man to beat in the bunch sprints.

So with the 10 bonus seconds on offer for the stage win that means Chris Froome is one minute one second behind the yellow jersey.

Interestingly, Mark Cavendish finished 36th in the main bunch. Not clear yet what meant he couldn't contest the sprint.

Geraint Thomas finished safely in 14th.

Chris Froome, speaking at the Team Sky bus: "I'm OK, we saw a lot of crashes out thre but we knew the first few days were going to be tricky, a bit sketchy, and that's part of bike racing.

"We were at the front of the peloton so there was not much more the guys could've done - t was just chaotic with the sprinters up there.

"I'm just grateful I'm not injured in anyway and there is plenty of racing left to Paris.

"I've not been checked by the team doctor yet but I feel fine."

In terms of the GC contenders - Romain Bardet, Rigoberto Uran, Tom Dumoulin, Mikel Landa and Vincenzo Nibali all finished in the front group.

Richie Porte, Chris Froome and Adam Yates lost 51 seconds to them.

Nairo Quintana lost one minute 15 seconds.

Lawson Craddock has made it across the line after his heavy crash earlier in the stage.

His shoulder looked badly damaged and he'll need stitches for those cuts around his eyes.

It would be a supreme effort from him to be on the start line tomorrow.

Sickener for Nairo Quintana - he punctured with 3.5km to go.

Had it happened in the final 3km, he would have been given the same time as the main bunch.

Adam Yates was caught up in the delays and ended up in the group containing Chris Froome and Richie Porte.

They crossed the line around 50 seconds down.

It looks like Romain Bardet, Rigoberto Uran, Tom Dumoulin, Mikel Landa and Vincenzo Nibali may be the big winners in terms of GC today.

Still a lot of timings to be confirmed but the top 10 on the stage is set...

1. Fernando Gaviria
2. Peter Sagan
3. Marcel Kittel
4. Alexander Kristoff
5. Christophe Laporte
6. Dylan Groenewegen
7. Michael Matthews
8. John Degenkolb
9. Jakob Fuglsang
10. Rafal Majka

Geraint Thomas may well have been in the front group and avoided losing any time. Chris Froome has taken a big hit today, but he can take some solace that several other GC contenders also suffered.

At the front, it was a dominant performance by Quick-Step to put Gaviria in yellow. A new sprint king at the Tour?

It looks like Nairo Quintana may have lost around a minute. A sedate day that turned savage.

Gaviria had his team-mates with him all the way to the finish line. Meanwhile here come the rest, trying to limit their losses. It has been absolute carnage for the sprinters and GC riders alike.

Richie Porte crosses the line and Chris Froome follows, it looks like they may have lost around 50 seconds.

Still no sign of Nairo Quintana.

Absolute carnage out of nowhere.

Chris Froome is still chasing, trying to limit his losses.

Colombian sprinter Fernando Gaviria holds off Peter Sagan to win stage one of the 2018 Tour de France and claim the yellow jersey.

Gaviria opens up his sprint, Sagan on his wheel.
