I have this exact thing, I’ve always had a high ish systolic B, I used to be a 20 hour a week training person that raced when I was around 20 and had a high systolic then. Now at my mid 40’s 
I’m training a fair amount (much less) and have a resting HR of around 44 and BP of 127 ish over 75 ish. Not to say I’m not about to keel over and die at any minute, I usually assume that anyway being a bit of a hypercondriac, but so far so good.
