Mark Cavendish will be among the sprinters and one-day specialists vying for victory on Sunday at the season’s first Monument classic, Milan-San Remo.
The 293km marathon is the longest race of the year and while it usually finishes in a sprint, late climbs and frequent bad weather mean that is not always a certainty.
Sprinters are high up the list of favourites, but the immense distance can drain them of their top speed, which brings classics experts such as Fabian Cancellara into play.
As well as Cavendish, there is further British interest in the form of Team Sky's Ben Swift, who finished third last year.
Here's what you need to know about the race...
THE ROUTE
Milan-San Remo is not a particularly technical or hilly race, but the challenge lies in its colossal distance. It takes in three regions of Italy - Lombardy, Piemonte and Liguria - as it moves from the edge of the Alps to the Mediterranean coast.
THE CLIMBS
There are six climbs on the route, the first of which, the Passo del Turchino, is largely inconsequential given that it comes less than halfway into the race. Then come a quick-fire trio of climbs known as the Tre Capi - Mele, Cervo and Berta - but it is the final two that there the most demanding and influential on the outcome of the race.
When compared with Alpine climbs, the Cipressa and Poggio are not significant ascents, but with more than 260km in the legs and the race speeding up ahead of the finale, they take on added difficulty and importance.
On paper the Cipressa is the tougher of the two and should thin the peloton down, but the Poggio is the make-or-break climb because it is here that breakaways will form or the riders who haven't got the strength to contest the finish are dropped. The climb is particularly crucial for sprinters such as Cavendish, who will have to hang on desperately as punchy climbers try to distance them with attacks.
THE FINISH
Once over the Poggio there is 5.5km to the finish. It could be that a group of four or five attackers break clear on the climb and they will frantically try to stay away on the descent down the other side, but the more likely outcome is the chasing pack will reel them back in ready for a reduced-bunch finish contested by sprinters and all-rounders.
THE FAVOURITES
Alexander Kristoff (Katusha)
Last year’s winner is back in search of a second successive victory and on what we have seen so far in 2015, he is the man to beat. The Norwegian has five wins to his name already this season so heads to Milan-San Remo in excellent form.
Mark Cavendish (Etixx – Quick-Step)
Cavendish has made Milan-San Remo his main target for the first part of the season and has trained all winter with this race specifically in mind. Those preparations have manifested themselves in some superb form so far this season – Cavendish is the most prolific sprinter in the peloton with six wins – but illness in recent weeks could hamper his chances.
Peter Sagan (Tinkoff-Saxo)
The prodigious Slovak has been misfiring so far in his first season with Tinkoff-Saxo but his immense talent means it is impossible to discount him from contention. He can get over the climbs, go on the attack and produce a fast sprint, so whether the bunch stays together or breaks apart, Sagan should be there regardless.
John Degenkolb (Giant-Alpecin)
Other than a fifth place in 2012, the big German has a poor record at Milan-San Remo but has started the season promisingly. He only has one win to his name, but his ability to get over hills and a fast finish ensure he should be in the final reckoning.
Juan Jose Lobato (Movistar)
The Spaniard finished fourth in last year’s race and is so far enjoying arguably the best season of his career, so he appears primed to challenge for the win this time around. The climbs aren’t a problem for him and he is getting faster by the race.
THE OUTSIDERS
Fabian Cancellara (Trek Factory Racing)
The Swiss maestro has been the most consistent performer at Milan-San Remo in the past decade, winning the race in 2008 and finishing on the podium in each of the past four years. Although he doesn’t have the fastest sprint, he does have almost unparalleled endurance, which means he is usually one of the quickest finishers.
Ben Swift (Team Sky)
The Yorkshireman finished a surprise and impressive third place in last year’s edition and has made Milan-San Remo his main goal for the first part of 2015. He has proved he has the credentials to perform well, but his sprinting form is largely an unknown given that he has been playing supporting roles for much of the season so far.
Michael Matthews (Orica-GreenEdge)
Matthews is one of the emerging stars of the sprinting world and goes into the race with good form, having won a stage and finished top of the points classification at Paris-Nice last week. He was well down in 78th in his Milan-San Remo debut last year, but expect him to fare far better this time around.
Gerald Ciolek (MTN-Qhubeka)
The German won the race in 2013 and finished ninth last year, so undoubtedly has pedigree and should be in the mix if it comes down to a sprint, but he is yet to show any sign of top form so far this season.
Sonny Colbrelli (Bardiani-CSF)
Not a household name, but the 24-year-old Italian finished sixth last year and 12th in 2013, so he is more than capable of getting to the final sprint and could be a handful.
