Chances are that if you’ve been following Sir Chris Hoy’s Le Mans journey so far, you’ll have already heard his famous Scalextric cars story.

It’s been woven into almost every interview the Scotsman has done since announcing he would be taking the wheel of an LMP2 racer at Le Mans this year. But if not, here’s the short version:

As a boy, the young Hoy would play with Scalextric slot car racers at home and, one year, received a miniature version of the Circuit de la Sarthe. With everything ready to go, Hoy asked his father why some of the cars have lights on, and others don’t. Ah, said his father, that’s so they can race at night, just like in the Le Mans 24 Hours.

Racing at night is something Hoy will have to get used to this year, as he’s currently scheduled to take the second stint of racing at today’s Le Mans, which will carry him into dusk and early evening. The Algarve Pro Racing team is starting 29th on the grid - towards the rear of the LMP2 field -  and the Nissan-powered Ligier JS P2 will be driven by Hoy alongside team-mates Michael Munemann and Andrea Pizzitola.

For Hoy, this is the completion of a journey which began back in 2013, when the six-time Olympic cycling champion first expressed a desire to go motor racing. The switch from two wheels to four has seen Hoy compete in the Radical SR1 Cup - the same championship which Autocar's own Mark Tisshaw entered last year - race in the British GT Championship, train alongside Nissan’s GT Academy drivers and, in 2015, pilot an LMP3 car in the five-round European Le Mans Series.
