Alexander Kristoff claimed victory on the final morning at the Three Days of De Panne to move into the race lead.
The Norwegian was well-placed heading out of the final tight right-hander to out-kick Italian rivals Sacha Modolo (Bardiani-CSF) and Elia Viviani (Cannondale) in De Panne.
Wednesday's stage winner Mark Cavendish (Omega Pharma - Quick-Step) was unable to contest at the head of the sprint after the Manxman struggled to move up sufficiently in the final kilometres.
The end result sees Kristoff move into a four-second lead over Arnaud Demare (FDJ) with Cavendish a further five seconds back in third place overall.
Earlier Russell Downing (NetApp-Endura) made his way into the day's five-man break on the 112.6km test, the quintet eventually finding themselves caught with 22km to go.
Prior to the stage there had been a number of high-profile abandonments with Flanders favourites Tom Boonen (Omega Pharma - Quick-Step) and Peter Sagan (Cannondale) choosing to climb off before the double header.
The race will be decided on Thursday afternoon with a final 14.75km time trial blast along the seafront in De Panne.
