Do You Run So Hard That You Taste Blood?

Steve Prefontaine"Somebody may beat me, but they are going to have to bleed to do it." - Steve Prefontaine

I ran a particularly hard workout about a week ago.  At the end of the run, had a familiar metallic taste in my mouth—blood. 

No, I hadn’t bitten my tongue.  During intense aerobic exercise, it is possible for some of the capillaries in your lungs to fail and cause minor internal bleeding.

The technical name for this is “exercise induced pulmonary hemorrhage” or EIPH.  It is well-known in race horses, but often goes unrecognized in racing humans.

No permanent damage is done, but the result is that you taste blood in your mouth.  Of course, if you cough up blood, you should see a doctor immediately. 

Have you ever tasted blood after a hard run?  Tell me in the comments.
