I am an avid cyclist who was using Skratch and then I read an article about the e-Fuel & e-Gel so I decided to give them a try, sure glad I did. I ride every morning and do longer rides on weekend and seem to have more energy and stamina when using e-fuel. on short rides I use e-gel and water and I gives me the boost I need to finish my rides. love the radical raspberry, it tastes awesome. at 65 I still enjoy the ride.
