Yes, that is correct. It is going to be a 12 hour this year. Will run from 10am - 10pm Saturday. Sunday will feature a couple of regional races hosted by NEOHIO and Nelson Ledges.
The idea behind Sunday is if someone has a novice permit, they can run the races on Sunday and be eligible for their regional competition license (yes, all in one day)
And Im almost 100% sure there is a discounted rate for any team that enters the 12 hour enduro who wishes to participate Sunday
