Fueling and Pacing

Your individual fueling and pacing strategy

To set up your personal fueling and pacing strategy we need three specific data points from you regarding your sweat and your carbohydrate demand:
Sweat loss (1/3)
You track with the BESTZEIT app how much fluid you lose per hour / training session
Sodium loss (2/3)
You determine with the Sweat Pack the amount of salt you lose and how much you have to substitute per liter drinking
Energy demand (3/3)
You figure out with the performance tests how much carbohydrates you have to take in at what power level
We then tell you in the BESTZEIT app in detail how much carbohydrates and salt you should substitute at what point of the race and what pace you should choose to reach you goals.
