Carb Loading FAQ
Do I need carb loading for a 5K/10K?
No – carb loading is only beneficial for events lasting 90+ minutes. Shorter races have sufficient glycogen stores without loading.
Why is training taper required?
Reduced training allows muscles to absorb and store extra carbs as glycogen, the primary fuel for endurance performance.
How to avoid GI bloat during carb loading?
Limit high-fiber & high-fat foods, eat small frequent meals, and test your plan in training before race day.
