The article was titled" Potential Adverse Cardiovascular Effects From Excessive Endurance Exercise". While I had heard rumors in the past that too much exercise was a bad thing, I had never read any of the evidence for myself. It was quite a disturbing read.
Although I thoroughly enjoyed the ups and downs of 140.6 racing, I must ask myself, "Is this really worth it"?
I'm not trying to discourage you ultra-marathoners, 140.6-ers, or your IM-ers out there from accomplishing your dreams or your goals. I do however think it's important that you know the facts, especially if you plan on sticking around the long stuff for a lifetime. ( especially if you fall into the older age group categories)
In addition to the damage on the inside, it's easy to see what years of free-radical damage can do to the outside. Not attractive in my opinion. Although this guy is pretty cute...
As for me, I think 3-140.6's is enough heart damage for a lifetime. As for now, I'm hoping to crush some dreams in the 70.3's and below. And while there are a million other reasons for me no longer to do the long stuff, this just helps make the decision that much easier.
