A six-car crash involving Sarah Moore, Ayla Ågren, Belén García, Abbie Eaton, Beitske Visser and Fabienne Wohlwend at Radillon de l'Eau Rouge marred the qualifying session held the previous day. Ågren and Visser were taken to hospital for precautionary checks where it was revealed the Dutchwoman had suffered a minor leg injury; both drivers were withdrawn from the race.[4]
The race began under safety car due to inclement conditions, but after 4 laps it pulled in and Chadwick led the field away to green. Caitlin Wood, who had qualified fourth and started third in her second event of the season, cut across the top of Radillon and allowed Emma Kimiläinen to draw close and eventually pass at Bruxelles. Wood's team-mate Marta García capitalised on the Finn's pass and made an initially unsuccessful move herself into Pouhon before sealing fourth around the outside of Campus.
Wohlwend – who had sat on provisional pole prior to the crash in qualifying – initially struggled in the conditions having outbraked herself in a move on Vittoria Piria for 10th at La Source, but recovered quickly and took the place a lap later. This began a charge through the field for the Liechtensteiner, disposing of Bunker team-mate Sabré Cook and Miki Koyama with ease. Kimiläinen and Marta García also had pace to burn, reeling in the leading duo by 2 seconds a lap – the former passing a grip-limited Alice Powell for second before setting off after Chadwick. The weekend was not going to plan for Bruna Tomaselli – the Brazilian was given a two-place grid penalty for missing the paddock entry gate at the end of practice, and was now dropping back behind the hastily-repaired cars of Eaton and Moore at a rapid rate.
Having cleared Powell, Kimiläinen was unleashed – with lap times 3 seconds quicker than Chadwick, she stormed around the outside of the Veloce Racing entry at turn 13 with four minutes remaining to take the lead. García meanwhile had struggled to get around Powell initially but undercut the Brit at Stavelot for the final podium place on lap 10. Wohlwend's fightback wasn't finished either, rounding up Nerea Martí on the last lap for seventh in an identical move to Kimiläinen's for the lead.
Kimiläinen took her first win of the season in dominant style, finishing eight and a half seconds ahead of Chadwick. Marta García closed on Chadwick after her move on Powell but ran out of time to improve her position, while Powell lost ground in the title race with her fourth place finish. Caitlin Wood rounded out a fine weekend in the top five some seventeen seconds behind Powell, with Jessica Hawkins barely hanging on to sixth ahead of Wohlwend. Tomaselli dropped behind Belén García before the flag to finish 15th, with Gosia Rdest the last car across the line nearly 1 minute 15 seconds behind the leaders on a difficult return to the championship.
