I'll be dropping off Molly across the country to do a 3 day backpack even before college orientation starts. Her 2 trip leaders will know about the Type 1 and I'm instructing Molly to give the glucagon and gel to them to carry (in addition to the extra test kit,test strips,infusion sets, insulin, and Lantus in case the pump breaks or her backpack floats away). She'll be hiking around 3-4 hours a day and will have to experiment with lowering her basal and dosing as well. I know she'll test often, I just worry about a low getting away from her too quickly! She works out hard for 1-1/2 hours at a time...but never for 3-4 hours. I'd love to know any tricks or ideas that I can pass on to her. I know there isn't a formula for this type of thing...but would just like to hear what has worked for you or your teen. Thanks!!
