Old Mill Marathon Relay

About the Event

The Old Mill Marathon Relay offers an exhilarating experience spread across 23 laps on a meticulously maintained 1.14-mile loop course. Teams can consist of anywhere from one to five runners, allowing flexibility and strategic planning for each participant's pace and stamina.
Runners have the freedom to strategize how they divide the laps among team members, running in any order they choose. However, it is essential that a new runner takes over after every lap to ensure consistent rotation and optimal rest periods before the next leg of the race. While we suggest maintaining a consistent rotation for each member's comfort and performance, this flexibility allows teams to adapt based on individual conditions.
A notable addition to this year’s event is the option for teams to share tailgating spaces with another team, offering not only camaraderie but also a financial benefit. Both teams sharing a space will enjoy a $20 discount per registration. For more details and specific arrangements, please refer to the “Questions” section of the official registration page.
The course is set to close after 5 hours from start time, ensuring all runners have ample opportunity to complete their laps within this timeframe. Embrace the scenic beauty and challenging yet rewarding terrain as you navigate through the Old Mill’s historic charm, creating lasting memories with your teammates in a race that truly tests both physical endurance and team spirit.
