The Tour de France resumes tomorrow with what should be a sprinter-friendly stage from Le Touquet to Lille - but it's the following day that sees one of the most eagerly anticipated days of the entire three-week race, as the peloton tackles some of the sections of pavé used in the Paris-Roubaix Spring Classic.
The last time the Tour de France tackled these roads, in 2010, it was carnage. Overall hopeful Fränk Schleck crashed out, Lance Armstrong was among others to lose time as the peloton splintered, and the stage was won by Thor Hushovd with Geraint Thomas second.
Also in a select front group was Fabian Cancellara - now a three-time Paris-Roubaix champion - who took the race leader's yellow jersey in the Tour that day.
Similar drama is expected on Wednesday, and in this video the GCN team have a look at the stage in detail and identify the key points on the rout of the stage. And bad news for the peloton - at the moment, there's a fairly strong chance of rain on the route of the race from Ypres to Arenberg.
As the cliché goes, this early in the race, it's not a day that the yellow jersey will be won... but it's almost certainly one on which one of the overall contenders will lose it.
Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.
