obviously you know this is too high as you are no fool & train for competitions.
The best cardio is on a bike at a moderate to high intensity, in other words good old "Fartlek" training..mix it up
just my opinion but knowing you ..you´re probably taking the piss 
No, BP is genuine reading, I gave blood as well last week so that normally drops it a bit
My normal BP while I was dieting was 125/73 or thereabouts
Its the extra weight and water retention
My Kidney function was 54 last bloods, that was of a creatinine reading, that would be high due to training and what I was taking
My lowest ever kidney reading was 45, that was about 6 years ago after I competed, it went back up to 84 3 months later
