Jenson Button has claimed that McLaren have plenty to be optimistic about as they continue preparations for the new season.
The British driver has admitted that despite an enjoyable break, he is desperate to return to racing and is excited for the new campaign, during which he will be partnered by Sergio Perez following Lewis Hamilton's departure.
Button told McLaren's official website: "I was in Hawaii for part of the break - I managed to fit in running a marathon, doing a lot of miles on my new bike, as well as seeing friends, relaxing and eating well.
"I feel absolutely refreshed and ready to go!
"I have to say, I always look forward to the start of a new year - I've never lost that enthusiasm throughout my entire career - and I think we have a lot to look forward to during the year ahead."
Button finished fifth in the Formula 1 drivers' championship last season.
