Brian Henton took the lead from pole position in Heat 2 in the works March 743 with Renzo Zorzi slotting into second in his GRD 374, next up came Alberto Colombo (GRD 374), Ulf Svensson (Brabham BT41), Luciano Brunelli (March 743) and Gaudenzio Mantova (Brabham BT41). Half way up the hill after the start there was a big accident, Tony Rouff’s GRD made contact with an Italian car blocking the track, Barrie Maskell stopped his Dastle on the pavement with nowhere else to go and was promptly hit by a couple more runners. A couple more cars joined in the fun on lap 2 including Brunelli whilst Svensson dropped to the rear of the field following a spin.
Back at the front it was still Henton leading from Zorzi, Colombo, and Mantova, Colombo demoting Zorzi to third on lap 3. Colombo then pulled away from Zorzi but could do nothing about Henton finishing some seven seconds down at the flag. Zorzi and Mantova spent the rest of the race battling over third, it became very physical on occasions with Mantova’s nosecone bearing the scars after the race.

The first two rows for the final consisted of Tom Pryce, Brian Henton, Tony Brise and Alberto Colombo. Henton made the best start to lead Colombo and Pryce but on lap 2 Superhen spun and dropped to third. Pryce now led from Colombo having passed the Italian without difficulty next up came Henton, Brise, Francia, Cinotti and Zorzi. Pryce soon left the others behind as he pulled away from the group battling over second place by a second a lap while Henton fell to the back of the field with a second spin on lap 5. Brise was trying hard to keep in touch with Colombo whilst Cinotti and Francia were just far enough behind to give him some breathing space. Unfortunately the race now fell into a rather boring procession with no one apparently able to get past anyone else.
Colombo had an unlucky lap 13, as he approached Ste Devote he lost control of the GRD and had an enormous accident from which he was lucky to emerge unscathed. Brise was now holding second following Colombo’s demise, third was Cinotti from Francia, Zorzi and Alex Ribeiro who was hampered by understeer caused by a damaged nosecone. There were no further changes to the front of the field and Tom Pryce came home an easy winner despite clipping the chicane with his rear wheel a few laps from the finish when he lost concentration. Brian Henton had clawed his way back to tenth place but yet another spin at the swimming pool saw his March hit the barriers backwards spelling immediate retirement.
