I’m on mdi so I can’t advise specifically, but it depends on a couple of things… First being, how fit are you? Is this going to be a stretch or a walk in the park? Your liver will dump glucose if you’re working hard, and not do too much if this is easy. If I’m hiking a challenging hike, I drop my basal. Make sure you take plenty of water, and glucose tabs (due to the precision of predicted bg rise), if it’s challenging, sometimes you will need to bolus to correct the high. Elevation can effect bg too, I find I need less insulin > 6k ft, It’s trial and error as you likely know. Have fun!
