Early Start Option: Marathon (26.2)

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

Please note that packet pickup opens at 6 a.m. which is the same time as the early start option.  This means that you will need to pick up your packet at the expo the day before the race.

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.

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.
