You have to be type A with Ironman nutrition! 🙂 Nice feedback.

Couple of notes…

1.  If you start using caffeine, you must keep using caffeine.  Thus it is usually recommended to use it later in your training day or race.  4-5 caffeinated gels is a lot of caffeine!
2. For the Infinit, Rebecca did speak to it and shared that often it is too concentrated thus causing GI issues.  Many of my athletes have had a similar experience with the side affects as well.

Fantastic!  Next?
