GU Half Marathon Endurance Fuel Bundle (Assorted Flavours)

The GU Half Marathon Endurance Fuel Bundle is a Racepack-curated 6-piece set combining GU gels and a GU Energy Waffle with Skratch Labs Energy Chews and Lemon + Lime Hydration Sport Drink Mix for flexible half-marathon fuelling.

GU's strength for endurance racing is its combination of fast-acting and longer-lasting carbohydrates, electrolytes and amino acids. This helps runners maintain carbohydrate intake through the race while replacing some of the sodium lost in sweat and supporting working muscles as the effort builds.

Flavour selection: GU Roctane Energy Gel, GU Original Energy Gels, GU Energy Waffle and Skratch Labs Energy Chews are supplied in random flavours according to available stock. Skratch Labs Hydration Sport Drink Mix is fixed as Lemon + Lime.

Because the assorted products include both caffeinated and non-caffeinated flavours, the total caffeine content of the bundle is not fixed. Check the individual packets supplied before use. For any queries, contact us on Whatsapp at 82825960.

Why GU for a Half Marathon?

A half marathon can last long enough for carbohydrate availability, hydration and fatigue to become increasingly important. GU is built around supplying carbohydrate in a compact format while also providing sodium and amino acids alongside the fuel.

• Quick + sustained carbohydrate: GU Original Energy Gel uses maltodextrin and fructose, giving you fast-acting carbohydrate together with a second carbohydrate source that is absorbed differently.
• Electrolyte support: GU gels contain sodium to help replace some of the electrolyte lost through sweat during running.
• Amino-acid support: GU Original Energy Gel includes BCAAs, while Roctane increases the amino-acid content for harder endurance efforts.
• More support when the race gets harder: GU Roctane contains more sodium and amino acids than Original Energy Gel, making it the higher-performance option in the bundle for longer or more demanding efforts.
• Different ways to keep fuelling: gels, waffle and chews give you different textures, while the Skratch drink mix adds fluid, carbohydrate and sodium so you do not have to rely on gels alone.

For a half marathon: GU Original Energy Gels provide compact carbohydrate during the race, Roctane gives you a higher-electrolyte and higher-amino-acid option when the effort increases, and the waffle gives you a chewable alternative before or during the run. The Skratch products complete the bundle with bite-sized carbohydrate and hydration support.

What You Receive

How to Use the Bundle

There is no single fixed order you need to follow. Choose the products according to your pace, expected finish time, carbohydrate needs, caffeine preference and what you have successfully tested during training.

Before the Race

If you prefer something chewable, the GU Energy Waffle can be used as a pre-race fuel option. A GU Original Energy Gel or some Skratch Labs Energy Chews can also be used if those formats work better for you.

During the Race

GU Original Energy Gels provide compact carbohydrate fuel that is easy to carry. The GU Roctane Energy Gel provides another gel option with more sodium and amino acids than GU Original Energy Gel.

Skratch Labs Energy Chews provide a chewable alternative that can be eaten a little at a time rather than consuming another full gel.

You do not need to consume every fuel product in the bundle during one race. Build your intake around your race duration and the fuelling strategy you have practised in training.

Hydration

Mix the Skratch Labs Lemon + Lime Hydration Sport Drink Mix with approximately 350–500ml water. It can be used before or during the race according to thirst and your tested hydration plan.

Nutrition (Per Serving)

The GU gels, GU Energy Waffle and Skratch Labs Energy Chews are supplied in assorted flavours, so exact nutrition and caffeine values can vary. Always check the individual product packaging supplied.
