Mtnbiker has a point about increased participation and possible decreased caution. Are the new runners cutting corners? Hope not.
My two marathons were post AVR - several years after. I'm one of those couch to marathon guys (53 weeks by the way). I was an overweight middle-aged novice runner with a "heart history". I checked with my cardiologist. He gave me the green light. He ran marathons in college (I guess before med school
). He now calls me his hero!
BTW, when I say "novice", I had run about 25 miles when I discovered VR.com (Mark, Les and others) and caught the marathon bug. It was about 25 more miles farther, and a month later, when I checked in with my cardio. M1 was about 8 months after that (no cracks about gestation
) M@ was 6 months after that.
My cardio also said that my heart function was normal. Talk about a paradigm shift! "Normal" changes everything. That's why I refer to having a "heart history" rather than a "heart condition" or "heart disease". Sure, there's some denial here, but to me the point of having the surgery was to get fixed, and not look back, and to not hold back. Not everyone has that positive outcome, and I think of those (you) every time I run.
I recall two things in my early reading about marathon training.
1. Don't consider a marathon until you have been running about 25 miles per week for about 6 months. Okay, I broke that rule by a few months.
2. Respect the distance. You can't cram for this test. Ya gotsta put in the miles.
Running that distance requires learning ..... about shoes, clothing, hydration, nutrition, and time management. And it takes a while to build up the mental toughness. Mental toughness is still a short suit for me - probably why I haven't run a third.
Still, having said all that, its hard to deny that marathoning is riskier than crossing the street. But Oh! (added for dramatic effect), the reward of the finish line is huge! I don't think that the last time I crossed the street, that I hugged my wife, kneeled down, said a prayer, kissed the ground and glowed for months! I'm not knocking those that don't run, but risks are balanced by rewards.
And when times aren't quite so rosy, I pull out the memory and shed a happy tear for being able to live life as I choose, and cashing in as well.
