HIGH5 Run Nutrition Pack

The HIGH5 Run Pack contains all the key products you need for race day. If you haven’t already got a belt to carry your gels, then make sure you add the Race Belt to your bundle – it’s designed to hold HIGH5 gels.

Energy Gel Aqua Caffeine

There is a selection gels in the Run Nutrition Pack but these are our go to gel for running because it has the consistency more like a sports drink so, unlike many other gels, you don’t need to drink extra water to swallow it. With 30mg caffeine.


With key electrolytes, sodium, potassium and magnesium, ZERO gives you what water can’t. Perfect to ensure you  stay hydrated throughout the day  – just add a tab to your water for a refreshing, great tasting sugar free electrolyte with zero calories.

Energy Gel Aqua caffeine hit

This gel is great for an extra edge before and during your training session or race. Just like Energy Gel Aqua, each sachet delivers 23g of carbohydrate energy but the Caffeine Hit also contains a high dose of caffeine (100mg). When taking part in tough sports events, caffeine contributes to an increase in endurance performance and capacity. That means you can go further than before!

Recovery Drink

A delicious tasting recovery shake for after your ride. Recovery Drink contains 18g of whey isolate, a top quality source of protein which contributes towards muscle growth and maintenance.
