Thought a 'normal 600k' was too easy?  Thought Ohio is flat?  Well, welcome to the crazy world of the SR600k.  

600km.  30,767 feet of climbing.  (Yes, that's more than Everest).  Still only 40 hours to do it.

DRAFT ROUTE linked.  Expect major revisions to everything, including start time.

Registration opens: Some time in the future...
