Fernando Alonso will set off airport security throughout the 2021 Formula 1 season following a cycling incident last month.
The two-time world champion broke his jaw when he was involved in a collision with a car in Switzerland, which required surgery.
The Spaniard will need another operation at the end of the 2021 season to have the titanium plates removed.
“I’m fine,” said Alonso ahead of pre-season testing at Bahrain.
“I’m happy to be here, back in the paddock and back in the sport first of all.
“After the accident four weeks ago, I had like 10 days to relax at home and after the surgery I had to relax a little bit. After nine, 10 days I went back to a very normal routine on fitness, preparation.
“I missed the team launch because the restrictions at that time were quite tough between Switzerland and UK but I was feeling fine. Ready to go tomorrow [Saturday] in the car.
“I don’t expect any issues, honestly. I’ve been training for now three weeks or two weeks, absolutely normal. I’ve been in the simulator as well Monday and Tuesday so the preparations were not affected too much.
“I missed only a couple of marketing days and filming days, which I was happy about in a way! Then I covered everything yesterday afternoon, I had a very intense day of marketing activities.
“I feel fine. Obviously one thing is the professional side and driving side, which I’m 100 percent.
“On the personal, I will have to remove two titanium plates which I have in the upper jaw which will be removed at the end of the season.
“So, still some things going on at the end of the championship but it will not affect my professional life.”
“I don’t fear any particular challenge,” said the 39-year-old.
“How the midfield is right now is very competitive, so it’s something that we are aware of, that we need to maximize and make perfection every weekend if we want to score good points.
“Then another challenge, not only for me but everybody in the team and in the paddock, will be the 23 races. We have to be aware of that number and try to save energy when you can during the year, even in the month of June, August, September, even if you feel fresh the more you save, the better you will be in November, December.
“There are a couple of things after being a few years out I will have to relearn a little bit and get used to but in terms of driving again or in terms of approaching the weekend working with the team, it should be quite smooth.
“I was not two years at home, I was racing every weekend basically, so it should be fine.”
