Fueling and Pacing

The components of your individual fueling and pacing strategy

To set up your personal fueling and pacing strategy we need from you data regarding to your sweat and carbohydrate demand.

In preparation for your next race, you should find out your individual sodium loss (with a sweat analysis) and your BIKE and RUN carbohydrate requirements (with carbohydrate tests) at the the beginning of each training block.
You can implement data of your already existing tests (e.g. sweat analysis or carbohydrate test) or get them on our website.

In addition to the results of the analysis we help you with our app to determine your personal sweat profile.
The results of all tests in combination to your sweat profile will determine your individual fueling and pacing strategy.
The 4th discipline

BESTZEIT takes the guess out of nutrition

Importance of the 4th discipline:
Comparing the single disciplines, your nutrition (carbohydrates, sodium loss and sweat loss) has probably the greatest impact on your race result. Nutrition can make or breake you on raceday - see figure.
So are you still guessing your individual needs or already measuring it exactly based on easily available data?
Our promise: 
We don't work with algorithms - we found a solution to handle athletes data and integrate it in your daily training routine.
We believe that training smarter and racing stronger is possible - everytime everywhere.
