"First laps at Le Mans! Mega circuit! Learning and enjoying every lap," he said on Twitter.

Alonso is combining the World Endurance Championship (WEC) with racing for McLaren in Formula One and has a busy schedule, with the Canadian Grand Prix in Montreal next weekend before he returns to Le Mans.

That is then followed by the French, Austrian and British Grands Prix on successive weekends.

Le Mans 'rookie' drivers, including Britain's 2009 Formula One champion Jenson Button, must take part in the test day and complete at least 10 laps after also undergoing a simulator session.

The day featured two timed four-hour sessions. Qualifying for the race starts on June 13.
