There is a 3.5 hour time limit that the course is closed and the aid stations are available. However, we may open sections of the course to let vehicles cross when there are large gaps in the participants and it is deemed safe. Participants must maintain at least a 14 minute per mile half marathon pace to make the course deadline.  All-In and Double Down runners will need to be finished within the same 3.5 hour limit. The course limit is set by the City of Lake Ozark and law enforcement.  It cannot be extended. Your races must be completed within the time limit or you will be scored as a DNF.
