Running Cut Back for Health Reasons

After consulting on January 17 with the physician/specialist/surgeon tending to my particular ongoing medical condition, I decided to suspend further participation in half-marathon races until the issue is eventually resolved. Instead, I will cut back my running to my old 1970s level, which was about 3-4 miles per run. I respect my doctor's recent more cautionary input (than what he told me three months ago), although in fact the recent test procedure I underwent produced no sign that things were worsening. However, the fact that he has run a marathon himself gives his advice more credibility to me than had it come from someone with a more sedentary lifestyle.

I hate to sound so cryptic about what's going on with me medically, but for the time being that's all I'll say for now, except that it is congenital in origin and can be surgically corrected. I am not suffering at all and continue to go about my business as usual. Life goes on like before, and so does my running...except that I'm neither entering half-marathons nor training for them.
