e-Gel and e-Fuel kept me strong on my first Adventure Race! I gave this product a try and was a little skeptical of how it could really work. Well, after the 5 hour bike ride up a mountain and a 1.7 mile run to the top of a mountain in between… I had no doubts. e-Gel also helped my teammates get through dehydration, exhaustion and cramps. Awesome!! We will have e-Gel with us on all of our races.
