Hello and welcome to live coverage of Stage 8 of the Tour de France - and after 18 consecutive bunch sprints and around 15 wins for Marcel Kittel, it's finally the first of two back-to-back days in the mountains. To be precise, the Jura mountains - the second of five of France's mountainous regions that the Tour will visit this year.

Confirmation of today's top ten - with Chris Froome also coming home in that main pack, 50 seconds down.

Brilliant day for Calmejane and his attacking Direct Energie team, who made a bold call not to bring Bryan Coquard on the Tour - but one that looks to be paying off.

The Wanty rider who took third place in the sprint, 50 seconds down, was Guillaume Martin, another 24-year-old French Tour debutant. Great day for the host nation.

Robert Gesink (LottoNL-Jumbo) crosses the line for second place 30-odd seconds back, before a Wanty-Groupe Gobert rider wins the sprint for third place when a reduced pack crosses the line...

An emotional win for Lilian Calmejane of Direct Energie in Station des Rousses. He's all smiles as he rides down the home straight, looks behind him, clenches his fist, then urges the crowd to roar and roar some more.

Under the flamme rouge for Calmejane, who can now afford to smile a bit.
Some downhill respite now for the lone leader ahead of the slight rise to the line. Back with the pack, there's some movement from riders wishing to steal back some time...
Calmejane is in a world of pain - but he's still 38 seconds ahead with a few kilometres to go. Provided he doesn't cramp up again, he should deliver.

The road starts to flatten out for Calmejane, who still has 30 seconds on Gesink and 1:20 on the pack.
It will be interesting to see if Gesink rallies, now. Calmejane seems to be recovering from those cramps, but it really was a big wobble.

OH NO! Lilian Calmejane almost comes to a standstill with cramp!! This has opened the door to Gesink... the Frenchman is really struggling...
Calmejane is holding nothing back as he hits the final uphill segment before the finish. It hits 6% but he should have enough. A superb ride from the Frenchman today. He tried to get in the break on numerous occasions before finally getting into that big move. When 16 went clear, he didn't panic and managed to get back in the mix before the final climb.

Calmejane still has 32 seconds on Gesink, 1:15 on Roche and 1:25 on the main pack. It's not in the bag, but it's looks good for the 24-year-old Frenchman. He won a stage in his debut Vuelta, now he's about to win a stage in his debut Tour.

The Team Sky-led pack crests the summit just as they catch Brice Feillu, who attacked earlier in the climb. They trail Calmejane by 1:25.

Over the top goes Calmejane - and he has 30-odd seconds to play with over Gesink. Polka dot jersey in the bag - but will he win the stage as well?
The gap is growing for Calmejane as he approaches the summit. Meanwhile, Valgren is about to be caught by the peloton.

Calmejane nears the summit - and this is a titanic performance from the Frenchman, who will take the polka dot jersey today. He already had a point this morning, so will have 11pts, which is one more than Aru...
Gesink is not giving up here. He's only 10 seconds down on Calmejane, and there's still 11km of this stage once the riders crest the summit - a lot of it downhill, some of it up, the rest flat.

Barguil has been caught by the peloton. There once was a time when Barguil was talked about in more glowing terms than the man currently leading this stage, Calmejane. But his stock has dropped over the past couple of years after that break out in the 2013 Vuelta, where he won two stages.
Gesink is really digging deep here. The rangy Dutchman has caught and passed Roche, and has the young Frenchman in his sights. The hardest part of this climb is to come.
