IRONMAN 70.3 Eagleman 2027
A tidal Choptank swim, 56 miles with only 330ft of climbing through the Blackwater refuge, and a flat double out-and-back run through Cambridge.
43 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? 70.3 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.

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.
“Three hundred and thirty feet of climbing in fifty-six miles, and thirty degree heat on an unshaded run. This is a pure engine course with a heat problem attached, and people underestimate the second half of that sentence every year.”
The race
The course
No course maps for this race. IRONMAN publishes no downloadable route for any leg of this race, only a live tracker that runs on race day, 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.
A counterclockwise rectangle starting and finishing at Gerry Boyle Park, in from the small beach and out at the boat ramp. Tidal: against the current outbound, with it on the way back in.
One loop with just 330 feet of climbing in the whole 56 miles, through country roads and the Blackwater National Wildlife Refuge. There are no hills at all, and the wind coming across the open fields and marsh does the job the hills would have.
A double out and back along the Choptank and through the residential streets of Cambridge, with an updated loop through the Algonquin neighbourhood.
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.
