LOL, I was just feeling old and decrepit yesterday (ok, after bounding through the snow when I went running in Tuesday's blizzard...still...) and I also agree that excuses can be a barrier. Exercising with diabetes has been a powerful incentive to keep diabetes in line as it usually takes me a couple of hours to clear IOB so, for that couple of hours, I keep an eye on things, perhaps "cheating" with a CGM to keep things in line. If I get drift either way BG wise, I take very small corrections if I need them or work around it, skip eating if it's drifted up or eat a bit more if it's drifted low. I have also been at it for a few years (since 2004-5 I think? That winter is when I started Tae Kwon Do, which I don't do any more, although the lessons are still there...) and agree that I got more bang for my BG buck back when I started and was not in ok shape like I am now. At first, I'd turn my pump way down and eat, then I cut back on the eating and then turned my pump "up" (less of a cut to the basal, I always think of it as %ages but I will do various "lucky" numbers, e.g. 7%/13% on long runs if it goes down, until I have enough sugar to see it start to come up, 40-60% for long runs when everything is smooth and no adjustment, with a small serving of quick acting carbs (8-10G) before a 3 mile run, which is typically 25 minutes or so. But everyone is different, none of this is "guaranteed" to work but it's more the method of testing and checking to see how you are reacting to various things and being aware of things. "I had sugar at mile 4, this low at mile 6 isn't too severe, I feel strong [my ability to hold a pace goes away if my BG gets low...] so I'm going to run home to check" may sound dangerous and I wouldn't say to do that if you are on your first 6 mile run, pull over at 4, pause your Garmin (vanity!) and test.
I also have updated my snack photo, of the little bag I stock with Starburst jelly beans and Smarties:
I have an Amphipod belt:
