I plan on running Hellgate with a Nathan hydration pack. I am concerned that the liquid inside the tube will freeze, preventing me from drinking. Any advice? I am thinking about wrapping something around the part of the tube that is exposed to the elements, but does anyone have ideas about what would be most effective (lightweight, flexible, with sufficient insulating properties)? I realize that Nathan sells a pack intended for winter use, but I don't want to have to purchase a separate pack. Any ideas would be appreciated.

How about a little added sugar and salt to your drink in th form of ultra fuel? That would lower the freezing point some. You could test a hydation fuel like succeed-ultra or perpetuum to see if the freeze in your home freezer.
perhaps you could try a foil wrap covered with some first aid paper tape for easy removal to provide tube insulation.

I will actually be using Perpetuem. I just assumed that the freezing point would be the same as water. Science was never my strong suit.

I had my tube freeze a couple of times last year on long runs. (one time it froze in the first four miles!) I had Gatorade Endurance in the bag, a North Face hydration pack. They also make the "winter" model that had insulation wrapped around the tube. Maybe somebody also sells the insulation that you can add later? Or you might try looking for some type of foam padding at Home Depot (shameless plug on behalf of the Prez). You could probably cut it to fit, roll it around the tube, and then tape it in place using duck tape (also purchased at Home Depot ).

Let us not forget that alcohol also lowers the freezing point. If someone actually suggest putting real anti-freeze in your drink, you need to remove them from your will This is what I got from www.platypushydration.com/about_us/faqs.aspx?Inside=2. I have no actual experience with drinking in cold weather, but this sounds like pretty sound advice. I am sure this isn't brand specific. HOW DO I PREVENT THE WATER IN MY DRINKING TUBE AND BITE VALVE FROM FREEZING IN COLD WEATHER? Sip often to maintain flow, or do not leave residual water in the drinking tube in between drinks. Also, keep as much of the drinking tube covered as possible or inside a pack or jacket. Good luck at Hellgate

Apparently REI sells tube insulators, so I bought one. It was NOT easy to get the insulation around the tube, but I eventually got it on there. Of course, now the forecast is for lows in the upper 30s and highs in the 50s. Oh well--maybe it'll come in handy for Mt. Mitchell Challenge or Hot to Trot.

I've always blown the liquid in the tube back into the bladder to keep it from freezing. If it's really cold, the bladder will eventually freeze solid, and you are screwed, but as long as you keep it under a jacket, you should be ok.
