I have used basically all the other energy gels and hydration drinks available. There was one energy gel and drink that I used more than others. Then I heard about Crank Sports through a running friend. I decided to try both products offered by Crank Sports and now I’m not looking back. I have found, during the time I’ve been using them, that I’m able to run longer periods of time with a lot less burn out and more energy. I take one e-Gel every 45 mins. and drink at least 20 ounces of e-Fuel every hour and sometimes I can go to an hour and 1/2 What an incredible difference the both have made in my running performance and and energy levels on long runs. And I’m 67 years old. Thank you Crank Sports for two incredible products.
