RE: Ironman training with an abdominal aortic aneurysm stent graft extension, an update:
It would appear that my strategy for reducing hip flexion on the bike (Guru designed for this purpose, plus non-use of aerobars - bummer) was successful (so far).
A CT scan a few days ago at the Cleveland Clinic revealed no untoward effects on my stent graft extension as a result of training for the 2014 Eagleman Half (lack luster performance, especially on the run, but that was expected given the interruption of my training by aortic surgery and a calf issue). Let's see how it handles Mont-Tremblant
I'm writing to thank everyone who provided input and to encourage those with aortic disease to not give up, and to do what they can do safely to stay in shape.
