Do you have any data on this? I always drink ice water. Never had a single issue.You don't want too cold of water when your body temp is way up. It can lead to esophageal spasm, abdominal pain ...etc, not so good stuff. IOW, avoid too big of temperature change.
I haven't done that yet but I agree that if I really want cool water later in a ride, starting with just ice would probably be best. Perhaps this might be a bit uncomfortable on the back since a frozen bladder wouldn't bend?Have you considered just freezing the entire bladder (leave a little room for expansion of the ice)? That will last a LOT longer than ice plus water.
What, a 6 pound block of ice slamming into your spine might be a problem? HTFU!I haven't done that yet but I agree that if I really want cool water later in a ride, starting with just ice would probably be best.

Slightly chilled water isn't in the same league as too cold of water (being near block of ice).Best water temperature for effective, rapid hydration: Slightly chilled (16°C / 61°F)
Taking little sip at a time and gulping down aren't the same thing.Never had a single issue.
On hot group rides, we stop at a convenience store and grab a bag of ice. Everyone fills their bottles with ice water. Nobody ever has issues.
Do you have any data on what is 'too cold' to cause the issues you described?Slightly chilled water isn't in the same league as too cold of water (being near block of ice).
After a hard climb on a hot day I'll gulp water from my bottle as fast as it'll come out. Neve had or heard of issues.Taking little sip at a time and gulping down aren't the same thing.

You skipped this...
Best water temperature for feeling refreshed: Cold (6˚C / 43°F)For many, the taste of the water is irrelevant, as they seek the sensation of stimulating refreshment. A research paper about oral cooling published by the NCBI in 2016 explains that when feeling overheated, cold water around 6°C provides a feeling of energizing refreshment.
Did you check the temperature of "too cold of" water that you gulped down? Without such data, it's hard to make objective case, isn't it?Near a block of ice? I (and others) freeze water bottles. You can't get your water any colder than that. Never had or heard of issues.

So ....do you have data or not?
IDid you check the temperature of "too cold of" water that you gulped down? Without such data, it's hard to make objective case, isn't it?As for my anecdote, I did have issue with stomach pain when gulped down icy cold water right after an intense exercise on a hot day.
My experience with stomach pain, a.k.a. abdominal pain after gulping down icy cold water right after an intense exercise on a hot day is personal description using common words. As for esophageal spasm, that would sound more medical depending on who is reading but it was general vicinity where my pain was. I did see some description of the effects of drinking icy cold water on Google search while ago.That sounds like a dangerous medical diagnosis. So do you have data to support it? Or are you saying that's an anecdote of one?
Hi, I'm on my 2nd Rogue, live in the desert and it works fine. It's small enough, with some raised sections on the back to allow some airflow. I don't chill my water much, but you can freeze a 1/2-full bladder, of just keep it in the fridge overnight, before loading w ice. One thing that can be a help is the insulated hose that you drink from. This helps keep the water that stays in the hose from getting real warm, (may not keep it cold). The Roque has enough room for arm-warmers, pump, tool kit, lite gloves and more, but it's not very wide, so it feels light on the back, (compared to something like the Mule). Personally, (& I've trained in 100+ temps for 30 yrs.), the protection from the direct sun on your back, outweighs the small amount of decreased evap-cooling, and, I drink as much as I want, never being concerned about running out.Yup, makes sense... especially if one's body heat is helping to keep the water warm.
Anyone have suggestions for a somewhat minimalist hydration backpack that does have decent insulation? By "minimalist", I mean that I don't want a full-blown backpack with 400 zippers and a ton of storage (I have CamelBak Mule for that.) For cycling, just one pocket is fine. The CamelBak Rogue looks ideal but makes no mention of insulation, making me think I should check-out other brands... but so far, the only brands that list insulation are some off-brands sold on Amazon, like this Mazama (?) one.
I road an 80 mile ride today in 90 degree weather and started-out with my CamelBak packed with ice water. By the time I used-up my two bike-mounted water bottles (yucky warm water) and started into the CamelBak, it was full of warm, plastic-tasting water as though I had never put ice in it. That got me wondering... should I even bother trying to keep water cold on long, hot rides? Is it even physically possible?
I did a search of these forums for this same topic and in 2008, a rider mentioned having a hydration backpack that had an insulated backpack that featured some magical reflective material that actually kept his water cold for nearly two hours. Unfortunately, the product no longer exists and I have not been able to find something similar in 2021.
Have any of you been successful and keeping relatively large quantities of water cool over long rides?
I'm considering buying a few thin freezer gel packs and putting them in the same pocket that the water bladder goes in in hopes of keeping the water cool, but I'm not sure if that'll just leave me disappointed and having to haul around slightly more weight and bulk for no gain.
I know a couple of freaks like you that can last on a quart of water on said 3-4 hour rides, and two of them never carry more than a single bottle. If I'm riding in those temps I'm slamming a 27oz bottle every hour.I’ve never used a hydration pack so I can’t speak on that.
I use the 24 ounce polar insulated bottles. I can easily go 3-4 hours and still have cold liquids at the end of my ride. I freeze some of my hydration drink in the bottle and then top them off in the morning with the drink that has been in the fridge. It depends on the temp outside on how much I freeze in the bottles. Today’s ride was 85-90* and it was still cold at the end of my ride. My first bottle I freeze about 1/3 full and my second bottle 1/2 to 2/3 depends how hot it’s going to be.
Been doing this for years and always have cold liquids on my rides.
