If you are adequately managing your T1, know how various foods and activities affect YOUR body and if you are in proper physical condition, you should not hesitate to venture out on this hike because of your diabetes. During my 60 years of allowing diabetes to live with me I’ve found that there isn’t anything I can not do - except that I can’t hold a license as a commercial [other than for my leisure] airline pilot.
Yes, I’ve hiked the forests for many days including parts of the Appellation Mountain Trail, alpine skied many full consecutive days and cross-country skied alone [just had to keep insulin warm] in remote forests.
Just go for it kid!!! But don’t forget to think.
