They'll be plenty of time for some well deserved play and rest in the coming weeks, but for now Lewis Hamilton is back in action in Abu Dhabi as he samples Pirelli's 2017 tyres.
Less than fourty-eight hours after losing the title to team mate Nico Rosberg, Hamilton was called upon by Mercedes to assume tyre testing duties initially assigned this morning to Pascal Wehrlein.
It's not clear why the German manufacturer decided to change its line-up and split its testing workload but perhaps it felt compelled to call upon Hamilton as a bit of retribution for balking at team orders during Sunday evening's showdown in the closing stages of the race.
Mercedes will run Hamilton in the morning and Wehrlein this afternoon, while Ferrari and Red Bull will also take to the track with Kimi Raikkonen on hand, and Daniel Ricciardo and Max Verstappen.
Pirelli's next extensive test is scheduled on February 27 in Barcelona, where all 2017 cars will appear.
