In his time away from Formula 1, Fernando raced in different categories and he is noticing the differences between them.
"There are many things that you can learn from any other experience, away from Formula 1," Alonso said.
"Because Formula 1 is very closed environment, you repeat the same thing every two weeks and the same exact routine every two weeks. Your driving style gets in a way the same for over the years, and you just follow in a way the instruction from your team.
"They are optimising everything in the car, and they are optimising as well your driving style, so they are telling you what to do - where to save the tyres, where to save the energy on the battery, where to perform the burnouts, how many to do before the start.
"Everything is so controlled that you are not able to improvise many things on a Formula 1 weekend."
Fernando Alonso competed with different teams in Formula 1 including Renault, Ferrari and Mclaren, winning 2 championships with Renault in 2005 and 2006 becoming the youngest world champion at the time.
"In endurance racing, you have to be yourself, much more than [in] any other race car. You are finding traffic in different places on different laps, in different time of the day, for every single lap," Alonso said.
"Every time you jump in the car, you have to share much more with your teammates. There is a lot more team work on endurance racing than Formula 1, so there are things that you are learning, and you are taking that different approach for your future adventures in motorsport.
Alonso raced with Toyota Gazoo Racing driving the TS050 Hybrid in the WEC, winning the 2018-2019 season and two 24 Hours of Le Mans. He also raced the 24 Hours of Daytona in IMSA two consecutive years finishing 38th overall, co-driving with Lando Norris for United Autosport (co-owned by Zak Brown) and winning next year's race Konica Minolta Cadillac in the DPi class with former F1 driver, Kamui Kobayashi, being one of his teammates.
"The same in IndyCar, I think the level of detail that you have to reach in terms of setup, in terms of preparation for the Indy 500 race, is much higher than any Formula 1 event.
"The cars are the same, and small details can affect the driving style, the performance, the overtaking opportunities. You have to anticipate some of the things that will happen in the next two or three laps.
Fernando went to the Indy 500 three times finishing in 24th and 21st place, he failed to qualify for the 2019 race, if Alonso wins the Indy 500 at some point he will become the only active driver to achieve the triple crown of motorsport, Graham Hill is the only driver to accomplish this achievement.
"There are many lessons that you learn in different categories that hopefully you can apply in Formula 1, or I can apply in the future."
In his time away from F1, Alonso also raced in Dakar for Toyota, finishing 13th with co-driver Marc Coma.
Fernando returned to Formula 1 this season with Alpine F1 after two years away from the category.
