I've had 5 stents and an angioplasty in the last 4 years. this is my first full season of riding with no problems. I can go full bore without hesitation. Average speed is up over 2mph this year and my recovery time is excellent. My cardiologist said I was in such good shape in September that he thought a stress test was not needed. Then he said the magic words, "See you in a year !!". I'll be 56 in November. I really believe riding is saving my life.
