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.
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.
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
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 EnergyTM
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

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
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.
