IRONMAN Maryland begins with a 2.4-mile swim in the fresh water of the Choptank River on the Delmarva Peninsula. Water temperatures can vary between 73 and 79 degrees Fahrenheit. The 112-mile bike takes athletes through Dorchester County and into the aforementioned wildlife refuge. The course is flat, fast and scenic. The day finishes with a 26.2-mile run on flat country roads offering numerous straightaways—opportunities for athletes to size up their competition.
