Lewis Hamilton has completed a day's worth of running at the Circuit Paul Ricard, host of the returning French Grand Prix, for Formula 1 tyre supplier Pirelli.
Pirelli is conducting a two-day test at the circuit to trial 2018 prototype tyre compounds, with Mercedes providing its W08 for both days.
Hamilton completed 114 laps of the 5.8km circuit under sunny conditions with a track temperature of 35°C and an ambient of 27°C.
Hamilton's Mercedes team-mate Valtteri Bottas is due to take over driving duties on the second day of testing on Friday.
Pirelli shares all of its data amongst every team and runs unbranded tyres during the test in order to avoid the involved team and driver gaining an unfair advantage.
