Lance Stroll says he suffered an impact of nearly 50G in qualifying in Singapore and racing the following day would have delayed his recovery for this weekend’s Japanese Grand Prix.

Aston Martin and Stroll took the joint decision to withdraw Stroll from last weekend’s race after his heavy crash on Saturday, despite the Canadian passing the required tests. With the team struggling as Fernando Alonso finished outside the points, Stroll doesn’t view it as a justifiable absence on performance terms but says it was the right decision to be fully fit for Suzuka.

“I’m much better than I was on Sunday!” Stroll said Thursday at Suzuka. “I’m feeling OK now.

“I was fine (in that) I was healthy to race but I wasn’t physically feeling good enough to do Singapore, which is the hardest race of the year. I felt it creeping up on me on Saturday night and I knew it wasn’t going to be fun waking up on Sunday morning.
