another night of hard cardio and the blood is back.

Seeing blood in your urine can cause more than a little anxiety. Yet blood in urine — known medically as hematuria — isn't always a matter for concern. Strenuous exercise can cause blood in urine, for instance...
http://www.uptodate.com/contents/exercise-induced-hematuria
Exercise is the one of the many causes of hematuria (increased red blood cells excretion in the urine) (figure 1). Exercise-induced hematuria can be defined as gross or microscopic hematuria that occurs after strenuous exercise and resolves with rest in individuals with no apparent underlying kidney or urinary tract pathology.

Recent strenuous exercise can produce transient hematuria by traumatic and nontraumatic mechanisms.
http://www.ncbi.nlm.nih.gov/pubmed/2184253
Strenuous exercise makes extraordinary demands. The transition from rest to intensive physical activity can cause pathological changes in various organs, particularly in the urinary tract. Hematuria (microscopic or macroscopic) is one of the abnormalities commonly found after sports activity. This phenomenon can occur in noncontact sports (such as rowing, running and swimming) as well as in contact sports (boxing, football and so forth). The pathophysiology can be either traumatic or nontraumatic. Renal trauma and/or bladder injury due to repeated impact of the posterior bladder wall against the bladder base can cause vascular lesions and consequently hematuria. There are 2 mechanisms of nontraumatic injury. 1) Vasoconstriction of the splanchnic and renal vessels occurs during exercise in order that blood can be redistributed to the contracting skeletal muscles, thus causing hypoxic damage to the nephron. This results in increased glomerular permeability which would favor increased excretion of erythrocytes and protein into the urine. 2) A relatively more marked constriction of the efferent glomerular arterioli results in an increased filtration pressure, which favors increased excretion of protein and red blood cells into the urine. It must be noted that sports hematuria differs from other conditions that may cause reddish discoloration of the urine due to physical exercise, such as march hemoglobinuria and exercise myoglobinuria. In the latter 2 abnormalities there is excretion of hemoglobin and myoglobin molecules in the urine and not whole blood or intact red blood cells. Sports hematuria usually has a benign self-limited course. However, coexisting urinary tract pathological conditions should be excluded carefully.

Just go see a dr. You have good insurance, use it.
Already done. I'm waiting for lab results and on a dose of antibiotics. In the meantime, I'm trying to figure out why it only happens when I run and then goes away the next time I pee.

March Hematuria seems to be the culprit. I have a naval corpsman friend who says he's seen that disorder before and my symptoms sound about right.
