Hello and welcome to (slightly delayed - blame it on South West Trains) coverage of Stage 11 of the Tour de France: the first summit finish of the 105th edition of the race. My apologies for running a few minutes late - I'll bring you up to speed right away.

Sagan has already been dropped by the leaders - his work for the day done. He'll just have to make sure he misses the cut now: yesterday a gruppetto including both Mark Cavendish and Marcel Kittel came home just 28 seconds shy of the cut-off point...

There's a lot of activity behind the break with a chasing group of 30 riders only 30 seconds down and another group of 12 a further 20 seconds back, with the peloton riding at around three minutes. Some interesting names in the first group: Gilbert, Chavanel, Pauwels, Van Garderen, Kangert, G Martin, Frank, Taaramae, Soler, Skujins, Valgren and the polka dot jersey Alaphilippe. In the second group we have the likes of Rolland, Nieve, Gallopin, Atapuma and Greipel...

After that early intermediate sprint we're already onto the first of four categorised climbs, the Cat.HC Montee de Bisanne (12.4km at 8.2%).

The world champion Sagan is part of a leading five-man break that also includes Warren Barguil (Fortuneo-Samsic), Damiano Caruso (BMC), Romain Sicard (Direct Energie) and birthday boy Dani Navarro (Cofidis).

We join the stage after a feisty opening 10 kilometres. Peter Sagan, the green jersey, is part of a move and has just taken the 20 points at the intermediate sprint - mirroring what he did yesterday - to move a massive 121 points ahead of Fernando Gaviria in the battle for green.

With the sun shining, Christian Prudhomme waved the flag a few minutes ago and got this stage under way...

The first major summit finish of the race is a carbon copy of June's Criterium du Dauphine stage won by the Spaniard Pello Bilbao. With four large climbs condensed into just over 100 clicks, we can expect a flurry of activity from the outset and a major shake-up on GC. Here's the official profile...

Yesterday, Frenchman Julian Alaphilippe took a maiden career win on the Tour de France – and a first this year for the host nation – with a marauding solo attack from a large breakaway to seize the polka dot jersey at Le Grand-Bornand. Also involved in the break on the first of three days in the Alps, Belgium’s Greg Van Avermaet extended his lead in the overall standings with a gutsy ride for fourth place. Read all about it below.
