The Course

View all of our course maps here.

Time Requirements

You have 3.5 hours to complete the race. A “Last Chance Pacer” will be provided for your events. These pacers will travel at the average pace needed to cross the finish line at three hours and thirty minutes. Your progress will be monitored throughout the race. If you fall significantly behind the “Last Chance Pacer”, you will be given fair warning to pick up the pace. If you can’t keep pace, you will be required to board a bus following the pacers to be transported back to the Start/Finish area.  We will close the half-marathon finish line at 2:00 PM, and begin incrementally reopening the roads to traffic leading up until the 2:00 PM cutoff.
