"Peace" Long May You Run
I would definitely encourage you to speak with your doctor about this. If you are able to control your BP through weight loss and exercise, perhaps you could get off the medication altogether. But again, check with your doctor before engaging in a strenuous training program.
Benazepril is an ACE inhibitor which does not have effects on the cardiovascular system like beta blockers do. Beta blockers slow your heart rate and breathing rate, which is why they are a poor choice for a runner. Benazepril can elevate your potassium level so you should definitley avoid taking any kind of electrolyte supplement w/o first checking with your doctor.

There is a discussion about this sort of issue on a bike forums I subscribe to. It deals with beta blockers and their effect on cyclists. A lot of blood pressure medications have beta blockers and the general consensus among us armchairs types is that it inhibits the hearts ability to pump as fast during strenuous exercise. I'm on a beta blocking bp med so I take mine after I exercise everyday so there will be as long a time period as possible after I take the pill and I do exercise. Hopefully when I get my weight back below 200 my bp will stabilize like it did after I lost 165 pounds a few years ago.
I am a bit older than you, have had issues with BP over the years, but have declined to medicate due to the obvious complications. I found to my chagrin that low-salt diets do not help, but low sugar/starch diets do. In fact, too little sodium will increase chances of adverse events in vigorous exercisers. Those "dash" diets are based on a misinterpretation of data from the old dash studies that found, on re-interpretation, that reductions in simple carbs had a greater impact on BP than salt reduction per se. It was the other things consumed with salt that were the problem all along. I'm not saying to ditch the meds - no prescribed medicine should be taken lightly, but I agree with the other poster that you can wean yourself off them in time, since running by itself should improve your BP outcome when dietary influnces are neutral. Watch for signs of hand swelling (hyponatremia) and don't drink too much purified water, and your electrolyte levels should stabilze on a lower simple-carb diet. Happy trails!
