Posts Tagged ‘Electrolytes’

As the readers know, I’ve never been too hot about manufactured foods and snacks while on the bike. Instead of dextrose, give me a peanut butter and jelly sammich. Instead of artificial flavors, give me some nutella. First Endurance has changed me forever for the better.

I received the EFS Liquid Shot in the mail, opened the package, and read the flask’s label. Vanilla? VANILLA? Liquid Vanilla is scary. There are so many ways it can go wrong. EFS did not fail, and actually made it kinda enjoyable. Saying that about an energy gel is a big compliment. The flavor is kind of creamy, and the viscosity of the gel is not intrusive on the flavor, or the enjoyment of it. This is because the liquid shot does not have any of the traditional gelling agents used in other products. The flavor does not linger for a long time in your mouth, it is still nice to have a sip from your water bottle after it but not necessary. About half way through my ride, I wanted to just drink the rest of the liquid shot, since the slightly sweet taste was becoming really enjoyable! 🙂

The flask is 130ml, and was able to get me through 40-50 miles with no problems. The perfect mix of dextrose, sucrose, and sugars did not irritate my stomach, and I was not craving solid foods or anything else. I was doing fine with my water, and the flask of vanilla gel goodness. One thing you must remember is that this flask is pure energy. Before or after the ride is the best time for the food, or any time you cross your stomach’s threshold for needing substance. This is something that will take a bit of time to learn, but the ease of sipping on the liquid shot was enjoyable enough that I have purchased one of their 32 oz refill bottles. This refill bottle is like 20-30 of your normal gel-shot packets depending on which ones you buy; the best part is that you don’t have a sloppy wrapper in your back pocket or right above the elastic of your shorts once you are done with it. The flask itself does not leak, has a pretty average spout releasing just enough depending on how you squeeze the soft plastic container. Feeding yourself becomes no-nonsense.

The EFS Liquid Shot also is a carrier for the basic necessities like sodium, magnesium, potassium, calcium, etc that we sweat out while on a ride. These ingredients do not make a significant influence on flavor, but can make the difference between cramping up or not on a hot day. Basically, it is jam-packed with electrolytes, and we’re not talking about Brawndo-type electrolytes

The only flavor currently available is Vanilla. First Endurance plans to introduce additional flavors of the EFS Liquid Shot later in 2010. I am hoping to try the berry flavor when it come out, since this product has been a hit.


  • Surprisingly great flavor
  • Large volume, compared to other “gels”
  • Perfect viscosity
  • Full of essential calorie based energy, amino acids, and trace elements the body needs.
  • Refillable flask is a bit more environmentally responsible, as compared to traditional “gels”
  • Does not irritate stomach


  • Price ($6 for a 5oz flask) While all prepackaged nutrition is typically more expensive than home-made products, First Endurance has done their homework, and guarantees that this product will do its job, and satisfy you.
  • Novelty – If this is something that you have never tried, it may be quite foreign to you, and possibly have you hesitate. Don’t worry, it’s worth a try!

Not going to lie, I still enjoy real food, but on a race, or gran-fondo, these are a must.

4/5 Stars
