“Cycling is a game for him” (Track Cycling)

How does he stand out so much from other sprinters?
I could say that he is very strong physically, that he is tactically untouchable as he masters the running patterns, that he embodies the new face of sprinting with his very long, very intense efforts… but what stands out to me The most about him is his attitude. Cycling is a game for him. He looks like he’s having fun. On the track, we see marked, tense faces, but he is almost smiling.
