As an annual rite, I typically ride in one or more organized centuries and other organized rides. All of those rides usually have a name that exemplify the ride in some way. For example "The Chilly Hilly" or the "Torture 10,000" or "Reach the Beach", etc. Additionally, I travel a bit and attempt to incorporate cycling when possible. So, I'm looking for possibilities for the next time I hit the road.
What is a notable organized ride that you have done, would like to do, or have considered? (A brief description and/or link would be nice as well.) Basically, I can of course google this, but that lacks the element of first hand experience that I feel I can get from this site. For all I know, something like the "Wilson County Wander" might be a superb hidden gem and by googling, it would never bubble to the top.
Since this is an international forum, metric centuries or other organized ride suggestions are also encouraged. (Although I'm not sure if these types of rides are common outside of the U.S.) As an example, I have done rides in the wine regions of the Pacific NW, and theoretically could find myself in wine regions elsewhere at some point.
Adjectives for outstanding could include things like, beautiful scenery, physically challenging, excellent support, etc...
Since this is a CW, only one answer per customer please.
