Hammer Nutrition

I've used this flask to carry a high-carbohydrate 'sugar-syrup' mixture for long race/ride fueling.

I prefer it to a similar capacity soft flask that I own.

I find the shape of the full soft flask more challenging when loading up my jersey pockets with other fuel at the outset of a long day. This product just works better for me.

Of course, as you consume the contents the soft flask will diminish in size. But, I find it prefer to work around the consistent shape of this hard flask rather than the shifting size variance of a soft one.

Leave the clear/transparent plastic cap that sits atop the 'nozzle'/mouthpiece at home. It is unrealistic to use that cap during a ride when you want to pull the flask from a pocket, sip from it, and return it to its place with one hand.

I actually switched to these gels a few years ago b/c I read an article by a triathlete scientist sort of person who ran tests measuring the amount of water you need to drink along with the gel it takes for various gels to be easily digestible. Supposedly more water = a bit harder on the GI system. Hammer Gels were some of the best in terms of needing less water. There were a few that were better but they were much more expensive brands.

I cannot tell you I totally understood the tests or their accuracy ..... but Hammer Gels have always been easy on my stomach even in high-temps, long rides, and high heart rates. Gonna just stick with them.

You need to find out where you are with Perpetuem. Maybe a full dose is too much? Maybe too little? I usually use HEED early on and then switch to a HEED-Perpetuem mix later on during a ride. Everybody is different. Find your mix, then enjoy the ride. Ive been using Hammer products, namely HEED and Perpetuem for quite a while (20 years) and Ive found my "mix". Once you find your sweet spot you will be good to go. I like to get my calories and nutrition from a liquid and not a solid as I don't want to have to waste energy digesting solids during a long ride. Hammer is science for endurance athletes. You do the fine tuning.

These contain a broader range of electrolytes than most other products I've seen, and they simply taste better.
