!35 systolic doesn't appear to be high if it is the result of exercise, and taking a hypertension medication at that point would have to be an extremely low dose so as not induce hypotension.

I would be much more concerned about the high pulse rate. i have had that experience, and discovered that my blood volume was low, causing my heart to pump at a higher rate to obtain good oxygen profusion, thus, of course, raising the pulse rate higher than the physical activity would normally require, and also raising blood pressure.

You could ask your physician to do the necessary tests to ensure that all is well with your body's renin-angiotensin system, which goes a long way in controlling blood pressure by controlling blood volume (extra-cellular water).

In addition make sure you're well hydrated, and if you drink coffee, think about cutting back - it's a Diuretic. In fact before taking any Diuretic, over the counter (coffee) or prescription, I would talk to a physician who specializes in Sports Medicine.

Running 10 miles in hot weather, even at the moderate pace of 10minutes/mile, can be life threatening if the runner is dehydrated, or as happened in the Boston Marathon some years back, has consumed to much water; two novice runners died of overhydration. Be careful, and read Wikipedia sites or find others.

Hope this was helpful,
