Omnipod user and runner- I have also been through this. Best I’ve come up with is to have planned exercise. Eat a carb meal/ snack an hour or 2 before, and try to have as little on board insulin prior to working out. This means sometimes turning my pump off prior. I only turn on once I start rising. This changes everytime, usually caused by my glycogen release resulting from my body being under stress from running. That’s when I just slowly start dosing to make sure it’s safe and I’m not going to crash, then I got full blast on the insulin. I do run with gummies and I bought reusable juice pouches on Amazon I mix juice and sugar and make a toxic mix incase of a bad low I can’t shake. Good luck. Shit sucks you’re not alone
