IRONMAN Maryland 2027
One of the flattest full distances anywhere. A tidal Choptank River swim, two laps through the Blackwater wildlife refuge, and a three-lap run through Cambridge.

48 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
Building for this one? Ironman training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Build my complete road.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“Under 500 feet of climbing in 112 miles means there is nowhere to hide and nowhere to freewheel. This is a race about holding one position and one number for five hours, and the wind across the marshland is the only variable.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, so there is nothing to draw a course map from. Everything below comes from the official course page, checked on the date at the foot of this section.
Tidal water, and the current depends on the tide at the swim start. In 2026 the swim ran on the outgoing tide: slightly against you on the way out, slightly with you coming back in. Check the 2027 tide at the start time. Sight for the current rather than the buoy or you will drift. The exit is at the historic Long Wharf.
Two non-technical laps into rural Dorchester County and through the Blackwater National Wildlife Refuge. Under 500 feet of climbing across the whole leg, so it is as flat as full distance racing gets. Not a closed course, so stay alert.
Three out-and-back laps along the Choptank and into downtown Cambridge, including the brick-paved High Street, with the turnaround on Poplar Street where the crowd gathers.
Not yet confirmed for this edition: transition locations, cut-off times, water temperature history. We publish these only once they are on the official course page, so check there before you pace off anything here.
