I have been running many years and doing road races and triahtlons. Not too long ago I did a marathon and my shoulders and traps got very tight and that transferred to breathing difficulties. I tried my usual run training after that and had the same problems. Never happened in all my years before.
I went to my doc and then to some specialits. I had EKG’s, echo cardiograhams, Cat Skans, complete blood work, stress tests, pulminary function tests, you name it. I was ok with everything.
Lately I have been running with no real issues; I ran today and damn if it did not happen again;; about 5 miles into a 10 mile run I got so tight it hurt and I had to run walk and then just walk the remainding 2 miles.
Lately I have taken on yoga and meditation for relaxationa and when I run I specifically think about relaxing my shoulders so I don’t tense up, but it still happened. It is so tight and then my breathing becomes very labored.
Not sure if anyone has heard of this. I don’t know where else to turn for advice.
thanks
