Hi Ryan! Fellow T1D here with a 670G. I'm at 475 jumps and all but a handful are with my pump attached. I've done up to 10 jumps in a day, avg is 5 and never noticed or had issues that stand out from background noise or packing exertion. I use temp target to keep my BG above 150 and take carbs as needed. Early on I tried to not wear it but found my bg was more unstable from not having insulin delivery for long periods (gearing up, dirt diving, waiting for tandems to board etc) I'm an ambassador for Medtronic and wearing the pump at "high altitude" is "off label" for them so they would say not to do it. Hope that helps and LMK if you have other questions! On a side note where do you jump? I know a couple other T1s and we are talking about a world record T1D jump someday LOL.
