Yeah, there's a big difference between pro cycling and biking to get around.

Of course, but there's also a big difference between a cycling race and a car race.

Neither are vital transportation, but one is a helluva lot more polluting for entertainment than the other.

Of course. All in saying is that it makes us talk about how cycling is a good alternative to motor transport. Doing the pro peloton to work isn't an option.

I suppose no pro sport is green.

SailGP claims to be trying, although I have... questions... about how they get both their boats and personnel from event location to event location, as well as the use of combustion-powered support boats during races. (Frankly, I won't really believe they're green until they've built a sailing cargo ship to schlep those racing catamarans around.)
