Watch: Onboard with Alex Zanardi testing the BMW M8 GTE at Daytona
Alex Zanardi is a living legend; there's no question about that.
As well as being an incredibly inspirational and humble human being, he is also a highly-admired figure in the Motorsport world.
After losing both legs in a horrific accident in 2001, Zanardi returned to racing in the World Touring Car Championship and won on multiple occasions.
As well as winning two Paralympic gold medals at London 2012 and Rio 2016, he's also dabbled with endurance racing in recent years, competing in the Spa 24 Hours in a BMW Z4 GT3 in 2015.
The same year he won his second gold medal, he was victorious at Mugello in an M6 GT3 for the finale of the Italian GT Championship at Mugello.
Continuing his affiliation with BMW, Zanardi enjoyed a remarkable DTM outing at a rainy Misano earlier this season, and announced last month that he would compete at the Rolex 24 at Daytona in 2019.
He's now begun testing the car, and BMW has released an onboard video of him using the adapted M8 GTE to race around the famous banked turns and infield sections of Daytona.
As he adapts to a new circuit and car to him, Zanardi narrates the lap and describes which corners present the biggest personal challenge to him.
Watch it here:
It's important to consider just how much a racing driver has to think about anyway - let alone when you're taking a hand off the wheel to brake and downshift.
When you realise the extra upper body strength Zanardi requires just to hold himself in position; you have even more respect for what he's doing.
It's quite something to imagine he'll be completing double or even triple stints in this thing come January, alongside 49 machines battling it out at different speeds in their respective classes.
It's been a pleasure to follow his career so far, and I'll have teary (as well as very tired) eyes from staying up beyond my bedtime to watch him compete in the 24 hours on the 27th-28th January.
I'm keeping my fingers crossed that he'll announce a Le Mans entry soon too.
