Sports Drink Suggestions

Nuun electrolyte tablets. They lack the sweetness but give you the electrolytes.

Seems you need more electrolytes.

I use Gatorade and add Nuuns to it to get more electrolytes that makes it equal to Gatorade Endurance but cheaper and in the flavors I like.

I get cramps as well and have upped my sodium intake even more so while racing in hot weather. I don't get cramps training only racing.

My goal is to take in about 1000 mg of sodium an hour thru what I drink and if necessary take extra sodium in endurolytes or Lava Salt.

One or two issues ago one of the triathlon magazines had a really good article on hydration and electrolytes...I'd recommend you try and find it and read it. 

It is a balance of taste, calories needed per hour and electrolytes you need all which is variable between triathletes. 

I also really like the Nuun tablets.  They provide the electrolytes without being super sweet like Gatorade.  I use that during my rides.  If they are longer, I tend to also take gels or Clif Shot Blocks.

I also try to make sure I am getting enough potassium when I train.  I've had problems with calf cramps, too.  Eating a banana about a half an hour before going out has helped me a lot.

I make my own.  In a gallon of water - 1 cup sugar, 2 packets Koolaid (you pick the flavor) 1 tsp salt, 1 tsp Lite Salt.  This is pretty heavy on the salt, but I need it.  I like doing it this way cause I can pick the flavors of Koolaid I like the best - for some reason most sports drink taste really awful to me, and also I can customize the amount of salt.

I also use Endurolytes (by Hammer) they are great.

I found the best tasting gel ever.

TASTES GREAT.

Cadreamer- Minus the sugar, this is the exact recipe that my vet recommends for our horses in the summer.   The Lite Salt is potassium choloride.  I never thought to add sugar and drink it myself.  Duh.

x3 on InfinIT.  I use that on the bike and Gatorade Endurance on the bike.  I did not completely eliminate calf cramps til I went with Succeed tablets (about 330 mg sodium v 50 or so per ecap)  Two per hour on hot days does the trick for me.

To the 2 persons that recommended InfinIT, thank you.  It's helped me, along with pretzels, Clif Shot Blocks (Cran-Razz, yummy).  The only thing about InfinIT (or most other sport drinks is that on the bike it spills a little and gets sticky.

Regarding cramps, check out my IMWI race report to read about nasty cramps during the swim -

A combination of (proper) nutrition, hydration, and training will get it solved.

I frequently use cytomax as a sports drink; though I am working with Infinite to find a better drink for long rides. I am also a fan of both nuun and Hammer E-caps. 

As it was stated, you need to find out what works for you.  One of the easiest ways to do that is to eliminate things that do NOT work for you.
