Infinit Custom Nutrition Review and Giveaway

It’s no secret that my nutrition during Ironman Austin 70.3  was a disaster. After exiting the swim, I had some stomach cramps but assumed they would settle on the bike. However, my plan called for consuming a package of energy chews every hour, along with drinking an electrolyte drink. But the more I ate, the more my stomach cramped. By the time I headed out on the 13.1 mile run, I couldn’t eat a thing and was in a lot of pain.

At the USAT National Championships in Vermont last year, I exited the water with the same stomach issues. Gotta stop drinking while swimming… However, I had a different nutrition plan this time. For the first 20 minutes I only drank water to give my stomach some time to settle before bombarding it with sugar, then I switched to a custom nutrition drink called Infinit. Infinit is different from other energy or electrolyte drinks in that it contains all the carbs required for endurance training and racing, meaning that you don’t need any supplemental nutrition, and it is completely customizable to the individual athlete.

Using Infinit meant that I was able to stay in aero much of the ride and had no packages to fumble with, open, or drop on the course. I got off the bike feeling great, and followed that by running my second-fastest 10k ever.

You can develop your own customized drink on Infinit’s website. You answer a series of questions on topics such as your racing personality, sweat rate, length of races/training, whether you suffer from cramping or GI issues, plus basic items such as your age, weight, and sport. After answering the questions, the Infinit OSMO-FIT system creates your customized nutrition solution. It’s fast, easy, and painless.

This is how I developed my drink. After Infinit came back with their suggestion, I couldn’t help playing around with the sliders a bit, increasing the caffeine, etc.

When I approached the guys at Infinit about doing a giveaway on my blog, they agreed right away. They also suggested I do a phone consult to check my formula was correct and to enable me to describe that in this post. The questions asked on the phone consult are the same as in the online questionnaire, but the fact that you’re talking to a human being makes things a little different. Ryan pointed out that I really need two formulas, one for long bike rides and/or Half Ironman races where I’ll need protein, and one without protein for shorter rides, Sprint and Olympic triathlons, and running. I’d been using one formula for everything… Ryan also pointed out that I had the protein set a little too high for someone my size, and moved a couple of the other sliders around based on information I gave him. The entire process for two formulas took 20 minutes!

When I hosted our club run today I put out some Infinit at the water stop for people to try. Good thing I did, because I grabbed a gallon of water from the garage that had been sitting around a little too long and had some furry items in it…probably just protein but no-one was willing to try. That meant they all got to sample the Infinit, and it received great reviews!

  1. I’ve never heard of Infinit, but I’m definitely going to recommend that my friends with GI problems look into it. I had some bad GI problems during my last race, and if I continue to have those problems I’ll be checking it out, too. I hope using Infinit continues to help take care of your problems and lets you race to your full potential!

  2. I know you have loved their products and I still have not tried them. I would love the opportunity to give it a shot.

  12. I’d be using the formula while running. Out of the flavors, fruit punch would probably suit me for my initial trial.
