Imola: Lewis Hamilton was a nine-year-old karting driver when he learned his idol Ayrton Senna died after crashing into a concrete wall during the 1994 San Marino Grand Prix.
More than a quarter of a century later, Hamilton still has vivid memories of when his father broke the news as the pair repaired his kart.
I remember I had to walk away from my dad, because my dad would never let me cry in front of him, Hamilton said on Friday while preparing for his first Formula One race on the Imola track where Senna lost his life.
I had to go to a different place and it was not so easy, Hamilton added, his voice quavering with emotion.
But I remember trying to challenge that sadness into adrenaline and I think I won that weekend. But the following weeks were tough.
This weekend's Emilia Romagna GP marks the first F1 race at Imola since 2006, when Hamilton raced in GP2 at the circuit. He returns as F1's new holder of most grand prix wins, after eclipsing Michael Schumacher last weekend by winning a record 92nd race in Portugal.
Austrian driver Roland Ratzenberger was also killed during the 1994 race weekend in a high-speed crash but Senna was a three-time F1 champion and considered among the series' greatest drivers.
It's just something we'll always remember, said Hamilton, who was given one of Senna's race helmets by Senna's family at a Brazilian GP.
I went around today and it was a really special lap just going around seeing this historic track, passing the hard reminder of where Ayrton crashed.
It is very surreal still for me when I go to places, where you drive through the tunnel in Monaco or you drive at the British GP where you know that the greats in the past have raced at those places, the Mercedes driver added.
