Hi, long time no talk from me but I finally felt I have something to contribute. It's not the same thing, but I do run on my treadmill for 6 miles a day, and I wear confidry24/7's when i do. I found out very quickly what John spoke about regarding chaffing and rashes. To combat this, I wear latex exam gloves and lather my diaper area with petroleum jelly paying special attention to my thighs and hips (incidentally, I also do this for my armpits as the same thing happens there), then I remove the glove I put on my diaper. Following this, I put on another glove and put a layer of the jelly on the diaper itself where it comes in contact with my thighs, and place some more in the openings of the legs all around. Wearing workout shorts over this I have not had the issue with rashes. Since I am a Fitbit nut and wanted the 100,000 steps badge, I had to be on the treadmill for almost 14 hours, staying hydrated and changing almost every two hours. This method kept my skin safe despite traversing nearly 51 miles. If you can keep a jar of petroleum jelly, gloves, and duct tape (just to make sure the tapes aren't compromised), this would almost be as important as which diaper you end up taking with you on your journey. That's just my two cents
