Fernando Alonso was happy to add World Endurance Championship races to his 2018 calendar because he finds them more enjoyable than Formula One.
Alonso once said a 25-race season would prompt him to quit F1, but his 2018 schedule stands at 27 races -- that includes 21 F1 races, his commitments with Toyota, including the Le Mans 24 Hours in June, and the Daytona 24 Hours he contested at the start of the year.
