Even the event organizers are surprised at the increase.
The Triple Crown is a 3-stage event on separate weekends, and are brutal for the hills.
Completing them has it's own rewards and earns a pretty special jersey.

The individual events are events in themselves. The Dairyland Dare is my pick.
It is limited to 1500 riders this year. Right now, registration is way up, into the mid 600's. At this time last year, they were in the 150's. Last year, the limit was 1200, and they slightly exceeded that. The "cushion" of adding 300 riders has already been wiped out. How many events have bratwursts at rest stops?
Don't want to "solo" the Dairyland Dare? Need some company on it? The Classic & Vintage subforum here had a blast last year, and it looks like they may have a bike swap and/or show this year. In true C&V style, they accepted all riders, even Chicago Bears fans. Only via RSVP, via this link:
I'm pretty sure this is on Facebook. I don't go there.
