I got the men's event on now. Instead of "look at the time" it's "look at the time on the Wahoo Element" (a Wahoo Element is a particular sports watch). Instead of the swim leg it's the Roka swim leg (Roka makes wetsuits). There's a Vinfast logo on screen all the time (Vinfast is a car brand and the title sponsor).
It's not just the commercials (I've seen a beer commercial so far) or the brand logos on the athletes, it's the fact that every single thing is "courtesy of x", which means that even between the ad breaks the commentators has to talk about sponsors.
This is different from soccer games, cycling races live Tour de France, most world championships, etc. But I recognize it from UFC and various clips I've seen from NFL and other American sports.
