The McLaren driver missed Thursday activities at the track after experiencing a bout of food poisoning. He took part in qualifying and Friday practice, but felt unwell after the Saturday sprint.
He was given the all-clear for Sunday’s race, but he conceded that he was in some ways “lucky” to have retired with an electrical issue on the 51st lap of the 71-lap event, having started to struggle after losing nearly 4kg in bodyweight over the course of four days.
“I was in a pretty bad way yesterday,” he said when asked by Autosport/Motorsport.com about his condition. “I’m a bit better today, I mean I didn’t do a lot of the race.
“I got to a point where I did start to struggle a bit physically, but then my race was over. I’m okay, I’m getting better every day, just the last day took a big toll out of me.
“Especially from Thursday. I didn’t eat for two days, I didn’t drink for two days, I lost three and a half, almost four kilos in weight. I really struggled a lot.
“Everyone thought I was fine after Friday, because I just did a good job, and we were quick, But it was quite the opposite. So I just need to recover for next weekend.”
Asked if he was helped when the adrenaline kicked in the race he said: “I mean already today I was a little bit better. I could have a bit of food in me before the race today, I could get some fluids in me, which is probably the most important thing on such a hot day.
“I’m sure if I didn’t break down and if I’d made the end of the race I would have been in quite a bad condition. So in a way I’m lucky that I didn’t, but it was also a shame.”
Norris acknowledged that in the circumstances it was difficult to perform within the car, but felt he could ultimately carry out what he needed to during the sessions.

“It’s tough, I mean the first one was FP1 on Friday where there was just so much going on for my brain, and I wasn’t getting out of the way of people very well. Just small things. I don’t think today cost me anything, we were just very, very slow.
“And even yesterday [in the sprint] it didn’t gain me anything, it didn’t lose me anything. Maybe on Friday in quali there were some little mistakes and misjudgements.
“But I always felt when I was in the car and on my lap, especially on a qualifying lap, I could do what I needed to do. But through…
