Loris Veneman and Jeffrey Buis were the winners of the World Supersport 300 races in Aragon, with Buis leaving this round in a privileged position to be champion: he has a 30-point advantage in the championship lead with only the Portimão round remaining.
In the first race, held on Saturday, Dirk Geiger (Freudenberg KTM Paligo Racing) was leading when the race was red-flagged on the third lap. The interruption was caused by an incident involving Lennox Lehmann (Freudenberg KTM Paligo Racing) and Antonio Torres Domínguez (Deza-Box 77 Racing Team/Kawasaki). Lehmann was taken to the hospital with a fracture in his right femur.
The race resumed for five laps and Geiger took the lead. The German held on to the position until he crashed in turn nine on the fourth lap. The fight for victory had a large group until the end, with Veneman beating his MTM Kawasaki teammate Buis by 0.033s. Daniel Mogeda (Kawasaki GP Project) completed the podium 0.049s behind, in a thrilling finish. The top six finishers were separated by less than one second.
New emotions in the second race on Sunday, where there was no red flag, but there was still an intense battle for the win. Buis led in the early laps, but only took the lead definitively on the final lap. He crossed the finish line 21 thousandths ahead of Matteo Vannucci (AG Motorsport Italia Yamaha), with Marco Gaggi (Team BrCorse/Yamaha) completing the podium 0.097s behind the winner. Veneman was leading at the start of the last lap, but finished the race in sixth place.
