Early Start Option: Marathon (26.2)

Plan on taking more than 6 hours to finish?  Choose our early start option when you register!

Please remember that there is no packet pickup race day morning for the Marathon. You must pickup your packet at the Expo the day before.

We will record your start time as 6 a.m.

You will need to have a headlamp and any hydration that you will need before 8:00 a.m. when the course officially opens and aid stations are available.

Remember that the course will be marked, but there will not be any police or volunteers on the course until 7:30 a.m. so you will need to follow traffic laws and it will be good to be familiar with the course.

The course will close promptly at 2 p.m.  At that time, if you are still on the course, you will need to move to the sidewalks.  You, of course, may finish the race, but the finish area will begin cleaning up.
