How each one works, by distance

High Energy Gel Single Serving Coffee

For a 5k race, this gel may not be necessary unless you need a caffeine boost. Consume it 15 minutes before the start.

Iso Fuel Gel - Green Apple

For a 5k race, this gel may be excessive unless used for pre-race loading. Consider using it sparingly.

PEAK Carb Gel

For a 5k race, the quick energy from PEAK Carb Gel isn't necessary, as glycogen stores should suffice. Consider using it post-race for recovery.

When to use each

The High Energy Gel by Biogen is ideal during initial and later stages of a race when you need a caffeine boost. USN's Iso Fuel Gel is best used mid-race when hydration and high sodium are crucial for preventing cramps. Peak Carb Gel is optimal for consistent energy delivery throughout the race, especially suitable for caffeine-sensitive individuals.

Using them together

For a complete fueling plan on long endurance sessions, consider using Biogen's High Energy Gel for a caffeine boost and quick energy. Use USN's Iso Fuel Gel for sustaining performance with hydration and electrolytes. Finally, include Peak Carb Gel for steady energy intake without caffeine, ensuring continued endurance without GI issues.
