Brendon Hartley has conceded that he has had a "tough" start to his Formula 1 career but believes the process will be "very important" if he wants to succeed in the sport.
Hartley made his debut at the United States Grand Prix with Toro Rosso, but it was part of a hectic schedule which saw him compete in the Petit Le Mans, 6 Hours of Fiji, US Grand Prix, Mexico Grand Prix, 6 Hours of Shanghai, Brazilian Grand Prix, 6 Hours of Bahrain and the Abu Dhabi Grand Prix.
"The learning process was steep and very important. It was tough. I’m not going to lie, especially with eight weekends on the trot," Hartley said at the FIA Prize Giving Gala in Paris.
"That was a good experience for me, to learn what that takes out of you and what areas you need to improve.
"That was the perfect introduction into Formula 1 in terms of preparing a season, having some real racing experience to start next year.
Hartley is looking forward to a well-earned rest, but is encouraged by the early signs as Toro Rosso begin a new relationship with Honda and he begins his first full Formula 1 campaign.
He added: "I’m looking forward to having a bit of a break, recharging the batteries, and coming back strong next year.
I’m hearing a lot of positive things out of Toro Rosso and out of Honda. I can’t wait to work alongside them next year, and hopefully prove my worth in Formula 1."
