Race day

How each one works, by distance

Head to head

For a short 5k, the GO Isotonic Gel provides quick energy without needing additional water, suitable for quick exertion.

GO Isotonic Energy Gel 60ml - Single Unit (Apple)

For a 5k, this gel isn't necessary due to the short duration. Focus on pre-race nutrition instead.

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.

Beta Fuel Gel + Electrolyte 60ml - Single Unit (Raspberry & Lemon)

For a 5k race, this gel is not necessary due to the short duration. Focus on pre-race hydration and a balanced meal instead.

The verdict by situation

Gut risk

GO Isotonic Gel has minimal GI distress risk due to low osmolality, but relies solely on maltodextrin. PEAK Carb, with a varied carb blend, might pose a lower risk of distress thanks to its multi-source approach. Beta Fuel balances high sodium content with a lower fructose load, potentially minimizing gut issues.

Carb ceiling

GO Isotonic is limited to 60g/h due to its single maltodextrin source. PEAK Carb and Beta Fuel exceed 60g/h ceiling with dual-source strategies, enhancing absorption rates.

For beginners

Beginners might prefer the Beta Fuel Gel due to its substantial sodium content, aiding in electrolyte balance, especially in warm conditions. It provides a stronger electrolyte boost than the others.

For experienced athletes

Experienced athletes may lean towards the PEAK Carb Gel for its dual-source carbohydrates, enhancing carb absorption rates during intensive training or long races, essential for maintaining energy levels.

Best value

The PEAK Carb Gel offers a great balance of value and performance with a good carb blend and moderate electrolyte content, making it a cost-effective option despite its higher initial price.

Final verdict

Choosing the right gel depends on your specific race needs. GO Isotonic Gel caters to quick energy refueling for short distances. PEAK Carb Gel fits longer races with its dual-source carbs and substantial absorption rates. For severe sweat losses, the high sodium content in Beta Fuel Gel is advantageous. Each gel serves distinct athlete levels and race requirements.
