That's the current "unsustainable" business model.
I'd argue the current model is most races are put on lose money, have bad or limited coverage and few sponsors as a result.
There are tons of sponsors out there, but few who see cycling as a way to promote their brand because the ROI doesn't add up for them because of the lack of exposure on TV it gives them
Look at Euro 2024, who on earth are Hisense? basically a Chinese Samsung make electrical tech stuff, they've paid millions to be involved in this tournament, just because they get massive exposure from it.
That same amount of money could probably have funded a WT men's team at the top level for 2 years at least, and yet we won't ever see Hisense sponsoring cycling.
We don't see Qatar Airways in cycling even though UAE as their rivals are.
Adidas, Aliexpress, Booking.com, FedEx, Mastercard, Coca Cola, Sony.
They're all spending millions more for tiny logos at a football tournament, when the same amount of money could get them title sponsorship of some of the biggest teams or races cycling has.
Cycling needs better coverage to attract those sponsors
