🚨 IRONMAN MARYLAND – TRAFFIC IMPACT INFORMATION 🚨
IRONMAN Maryland returns to Cambridge and Dorchester County this Saturday, September 19, 2026.
Throughout the day, approximately 2,000 athletes will be participating in the swim, bike, and run portions of the event, resulting in temporary road closures, traffic delays, detours, and increased pedestrian and bicycle traffic throughout Cambridge and Dorchester County.
Some traffic impacts will begin as early as 6:30 a.m. Saturday and continue into late Saturday night/early Sunday morning.
If you will be traveling in or around Cambridge or along the race course, please:
Plan ahead and allow additional travel time
- Use alternate routes when possible
- Watch carefully for cyclists, runners, volunteers, and traffic-control personnel
- Follow all posted detours and directions from law enforcement and race personnel
- Review the attached official traffic-impact map before traveling
📍 Please remember: 9-1-1 should only be used for emergencies. Road closures, traffic delays, and detour information related to the race are not emergencies. Reviewing the traffic-impact information in advance will help keep 9-1-1 lines available for those who need immediate police, fire, or EMS assistance.
Our Emergency Communications Specialists will be working throughout the event alongside law enforcement, fire, EMS, emergency management, and race personnel to help coordinate public safety operations across Dorchester County.
