Mercedes driver Lewis Hamilton was hard at work on Thursday as he took to the Paul Ricard Circuit in France to undertake important tyre testing for Pirelli ahead of the 2018 Formula One World Championship.

On a sunny and perfectly clear day, the three time F1 champion completed a total of 114 laps of the French track.

While the times he set are unknown at this point, they weren't really relevenat as he was the only driver on track and fast times were not the purpose of the test.
