A windy morning chilled the track temperature to 21ºC in spite of the air being 20º, World Supersport would be an 18 lap race around the historic Assen track.
Randy Krummenacher didn't make the grid. He joined the warm up lap from the pit lane and started the race from last place. His sixth place on the grid was empty when the lights went out and Lucas Mahias made a blistering start to take the lead into there first turn, ahead of Federico Caricasulo and Jules Cluzel. Lots of places were swapped on the first lap but further back, Sheridan Morais and Hikari Okubo ran off with Morais unable to rejoin.
Lap two, Jules Cluzel started in second place but took the lead at the first turn, leading Lucas Mahias, Federico Caricasulo, Sandro Cortese and Raffaele De Rosa. Randy Krummenacher was up to thirteenth place and Luke Stapleford set the fastest lap latching on to the front group.
The leading seven riders were a group on lap three as the pace increased with Raffaele De Rosa setting the fastest lap until Randy Krummenacher went even quicker climbing to ninth place. As Rob Hartog dropped off the front group, the leading six started fighting amongst themselves. Federico Caricasulo tried to pass Lucas Mahias but Sandro Cortese took third place off him and had Raffaele De Rosa follow Cortese. Luke Stapleford at the back of the leading six looked like he was trying hard to keep with the leading group.
At the end of lap five, Randy Krummenacher took seventh place from Rob Hartog at the Geert Timmer chicane and stared at a three second gap to Luke Stapleford in sixth place on the back of the leading group. On the sixth lap, Krummenacher dragged four riders behind him, but he broke free as Stapleford started to lose his grip on the front group. On lap eight, Stapleford left the leading five to their fight for the win as Sandro Cortese tried to wrestle fourth from Raffaele De Rosa while De Rosa was aiming at Lucas Mahias, Cortese and De Rosa changing places back and forth several times until the GT chicane at the end of the lap. De Rosa pushed Mahias in the chicane and Mahias fell to the back of the group in fifth place, behind Federico Caricasulo, making sure he didn't hit anyone returning to the racing line.
Randy Krummenacher set the fastest lap. And again on lap nine. As he closed up on Luke Stapleford, he set the lap record on lap eleven, taking sixth place at the last chicane. A lap later, Krummenacher was in fifth place and well and truly in the leading group, catching Lucas Mahias and passing both Mahias and Federico Caricasulo who ended up in a fight with Luke Stapleford that didn't end well for either of them.
Mahias and Krummenacher passed Caricasulo and he was flustered enough that he ended up starting lap thirteen behind Stapleford and the pair duelled for a few corners until Caricasulo passed Stapleford only to have Stapleford to make a stabbing pass, thrusting into the spot where Caricasulo was trying to kiss the apex, and Stapleford nudged Caricasulo, or Caricasulo closed the door on Stapleford, depending on which rider's side you took. Race direction took Caricasulo's side. Caricasulo was pushed off his line and he lost grip and the bike and rider separated as the bike slid for miles across the overrun.
On lap fourteen, Krummenacher and Cortese exchanged third place several times, behind De Rosa and the leader Cluzel and a lap later, Cluzel and De Rosa swapped the lead a few times but they started lap sixteen as a group, of five riders, Cluzel, De Rosa, Krummenacher, Mahias and Cortese and this group just stuck together as all their tyres were worn in similar ways. Krummenacher took second from De Rosa at the Geert Timmer chicane to start the last lap in second.Throughout the last lap, Krummenacher looked for a way past Cluzel, trying to pass and set up passes throughout the lap, but as they drove through the chicane, as four riders, Krummenacher slid at the entrance to the last kink of the chicane, giving Cluzel the win. Krummenacher took a close second alongside De Rosa and Mahias. Cortese in fifth place couldn't make an attempt at a pass as he was three quarters of a second from the fight for second place.
Stapleford was penalised thirty seconds and he ended the race in sixth place on track but fifteenth place on paper.
Jules Cluzel lept up to fourth place in the championship with his win, while Randy Krummenacher took second place from Sandro Cortese. Lucas Mahias's lead was cut to only one point.
