Thanks Ross. I tried too, with another shot, but had the same problem. Oh well. Runner, I'll send you a PM to give you the whole scoop!

PS Runner: I would find a more supportive cardiologist. (I don't mean to be blunt.) He should be giving you detailed reasons for holding you back. For gosh sakes, heart transplant patients have run marathons. With a structured program their is no reason you should be held back. If you can run a half marathon, in my assessment with proper training, you can RUN a full marathon. Maybe it is just a liability issue, and he dosen't want to stick his 'hiney' on the chopping block, but that should be NO reason he should be holding you back from your dreams and goals.
