Crank Sports is so confident that e-Gel Electrolyte Energy Gel will improve your next marathon performance that we are willing to put our gel where our mouth is - we'll guarantee it.

Our Guarantee
If you use e-Gel in your marathon training and on race day, Crank Sports will guarantee that you'll run a personal record (PR) time. If this is your first marathon, we guarantee that you'll be a first time finisher. If you don't set a PR, we will send you a free 16-pack box of e-Gel (valued at more than $30 with included free shipping).

Why are we so confident?
Finishing a marathon has always been considered a tremendous athletic feat, and many experienced marathoners will tell you that there are two halves in a marathon - the first 20 miles and the last 10 kilometers. One reason for this is that your glycogen stores (your primary source of energy) can only hold about 2,000 calories and the average person burns approximately 100 calories per mile. Do the math and you'll see that your glycogen stores can only provide enough energy to take you approximately 20 miles. Fat can also be used for energy, but fat is a very inefficient fuel - you won't be setting any speed records relying on fat alone!

Fortunately there is a third source of energy - blood sugar. The beauty of energy gels is that (when taken properly) they are rapidly absorbed in your small intestine, thus providing energy in the form of blood sugar that can supplement your glycogen stores. If you start consuming energy gel early enough in the race you can greatly reduce your body's need to rely on fat as an energy source.

Why e-Gel and not one of the other brands?
All energy gels are designed to provide quick and convenient energy, however, energy is only one part of the equation. In a marathon or any endurance event, you also should be concerned about proper hydration and electrolyte balance.

All energy gels should be taken with water (and not a sports energy drink) so that they can be quickly assimilated by your body (more info). If you do not maintain adequate water intake with your gel, it can slow the absorption rate and possibly cause stomach irritation and/or dehydration. So, if you're taking water with your energy gel as you should, then you are getting energy (from the gel) and hydration (from the water), but you are not getting significant electrolyte replacement - that is unless your gel is e-Gel.

e-Gel's patent pending Electrolyte Energy
TM formulation is designed to provide complete and balanced electrolyte replacement in addition to sustained energy and hydration when taken with water as recommended. For additional information, view our product advantages and competitive comparison.

Marathon PR Guarantee Program Requirements
To qualify for the Marathon PR Guarantee program you must sign up and start training with e-Gel at least 30 days prior to your race. Your supply of e-Gel must be purchased on-line to allow us to confirm that you have the product. Thereafter, we have no way of verifying whether or not you actually train or race with the product, but we trust you'll be honest with us. There's no paperwork to complete, no proof of purchases to submit - instead we prefer that you concentrate on your training.  After your race, just return to cranksports.com and let us know your marathon time, if it's not a PR we'll send out your free e-Gel to help you start training for the next one. Enrollment in the Marathon PR Guarantee program is limited to one time only per person.

Obviously there are many things that can go wrong on race day that have nothing to do with your race nutrition. Not a problem. We will honor the guarantee regardless of the reason for not setting a PR. Likewise, as you age it is difficult to equal the performances of your youth, but then again you probably didn't know as much about running and nutrition as you do now. So even if you set your PR 40 years ago, we will still honor the guarantee. All you have to do is make it to race day and give it your best shot.
