This its truly one of the most beautiful metric centurys I have ever done.

Agreed. Very nice ride. They also run the same or similar ride in the fall under a different name (there may also be a 100 mile option).

Don't know about this year but never 100 miles in the past. If you want options up to 100 miles in the same area, try Cyclefest in Bethel June 12th (hatcitycyclists.org). It has more varied routes and scenery and less riders which both appeal to me.
