When it comes to fueling while on the run there are many available options, there are Gels, Chews, Jelly Beans, Drinks, Gum, the list goes on. How do you know which ones to consume? Will they help or hurt your performance?

Stick with me through this article and you’ll have a chance to win some Science in Sport Isotonic Gels!

Choosing the right fuel to suit your needs can be a gamble, and that’s why many suggest not to try anything new the day of a race. I’ve heard horror stories from friends who took Gels or Chews for the first time during a race and rather than getting the boost they needed, ended up with stomach pains and cramps so bad they had to *gasp* walk!

Where to begin?

With the many available options out there, you’re probably wondering how you can choose the right fuel. In fact, most of my experience with fueling has been achieved by trial and error until I’ve found the perfect match. But, that takes time (and money), so let me save you some hassle.

Science in Sport Isotonic Gels

I’ve had the best experiences with Gels, they are a quick and easy energy source that can be consumed on the move and can provide that boost of energy you need to help you go the distance. Energy Chews and Jelly Beans are ok when you have a moment to actually stop and eat, but when it comes to on-the-go fuel, Gels are at the top of my list.

When I received my samples to test I noticed these claimed to not give you an upset stomach, a very common side effect from Gels when taken for the first time. So naturally, I decided to consume some of these Gels on an empty stomach right before a long run.

To my surprise, I was able to run cramp and stomach pain-free!

Now’s your chance!
