It’s a sunny spring day, and Sir Lewis Hamilton—the Formula 1 GOAT, god-tier watch collector, and former GQ Style Champion—is getting a tennis lesson from Frances Tiafoe. Big Foe, as the latter is nicknamed, is the world’s number 12-ranked player and, like Hamilton, a player of color from a working-class background in an elite sport. He instructs Hamilton how to properly swing—upward, brushing the ball—for a topspin forehand. Unsurprisingly, the seven-time Formula 1 champ gets the hang of it quickly, knocking out three in a row. “OK, Lewis Hamilton!” Foe chirps.

That whole scene takes place in a mini-doc called Rest Day with Lewis Hamilton, the second in a series produced by Lululemon, the proto-athleisure brand that sponsors both athletes. (The first edition saw Hamilton working on his long game with Min Woo Lee.) In between lessons in the finer points of hitting, the pair discuss a range of topics, from the value of representation to their shared love of European candy.

Ahead of this weekend’s US Open start, where Tiafoe is slated to compete in the men’s singles main draw, and following Hamilton’s return to Formula 1 after that sport’s summer break, we caught up with the guys to chat about their shared experiences, ice baths, and Hamilton’s ongoing mission to diversify Formula 1.

GQ: From both an athletic and a personal perspective, what do you guys admire most about each other?

Lewis Hamilton: I think what’s struck me is how mature Frances is at his age. He started his sport at just three years old. A little earlier than me, since I started at eight. He just seems further ahead in terms of maturity and technicality in his training than I was at that age. We share a lot of similarities, too—we both hate losing.

Frances Tiafoe: Lewis has class. He’s a tremendously hard worker, and he understands the moment—breaking the mold, doing well in his sport, it brings a totally different demographic and set of eyeballs to it. He gives back to people, and hopefully that means more people like him are playing the game. I feel like I am in a similar seat, so there are a lot of parallels. And I admire just how humble the man is, given all of the success he’s had.

Can you draw any similarities between Formula 1 and tennis?

Hamilton: Fast reactions are key for both. Thinking on your toes, hand-eye coordination—very similar. There’s a real similarity in how you take in what you’re seeing, digest it in a split second, and react.

Tiafoe: These sports are also expensive to get into. And, obviously, there’s a smaller margin of people of color playing in both. Formula 1 is not the easiest sport to get into for anyone, for any walk of life, because of how few people are in it. But I think that’s especially true for people of color, growing up in certain communities. Everything you do in both sports is a significant expense, compared to, say, football or basketball. In tennis you need rackets, you’ve got to travel, you need coaches. This is a similarity between the two sports, but it’s also a challenge.
