There's a good discussion brewing in the Ghent - Wevelgem thread about the relative prestige and popularity of some of the one day races. I thought it would be cool to have a thread about it. Adapting the star format from
@Volderke , I'll put my two cents in.

Less confident about this but I'll take a crack:
Most Prestigious:

I will say I think the Olympic Games RR is the most prestigious and often quite a good watch, but I left it out because it's only every 4 years. Whatever y'all want to do is fine.
* The worlds is so course dependent. Could be 5 beers, could be 2 for me.
** The jersey to wear all year and the title are hugely prestigious.
Let the mayhem begin!
