The Marathon Running Kit gives you energy, electrolytes and a recovery drink for a 3–4-hour marathon, at a better price than buying them separately: Hammer Gel and HEED during the race, Endurolytes for electrolyte replacement, and Recoverite after the finish. You choose the flavours of the gel, the HEED and the Recoverite – you focus on running, we’ve put your fueling together.
What’s in the kit:

The Marathon Running Kit brings together the products we think you’ll need for a 3–4-hour marathon: energy and electrolytes during the race and a recovery drink once you cross the finish line – at a better price than buying them separately. You choose the flavours of the gel, the HEED and the Recoverite.
The gel and the HEED provide energy, Endurolytes provides the electrolytes, and you drink water at the aid stations. That way you can adjust each one separately to your pace, the weather and how much you sweat.
The kit is mainly designed for a 3–4-hour marathon. If you’ll be out on the course longer than that, Perpetuem should be the basis of your fueling – write to us and we’ll help you put it together.

On the product page, you can choose the flavours of the Hammer Gel, the HEED and the Recoverite before adding the kit to your cart. The 4 gels come in one flavour, and the 4 HEED servings also come in one flavour.
For a 3–4-hour marathon, yes. The 4 gels and 4 HEED servings together provide about 800 kcal – at 120–180 kcal per hour, that’s enough for around 4 hours, and the 12 Endurolytes capsules also last that long at 2–3 capsules per hour. If you’ll be out on the course longer, you may need Perpetuem or extra gels – write to us and we’ll help.
Because while you’re running, your body can only process a limited amount of calories, no matter how many it burns. Too much energy puts a strain on your stomach and often leads to digestive problems. If you feel it’s not enough, increase it gradually – it’s always easier to top up a little than to deal with the consequences of taking in too much.
Yes, that’s one of the things it’s for. A lack of the electrolytes lost through sweat is one of the common causes of cramps in long races, and Endurolytes replaces exactly these – sodium, chloride, potassium, calcium and magnesium – in balanced proportions. Magnesium and calcium contribute to normal muscle function.
It’s important to know that cramps can have several causes: fatigue, an unusually fast pace, heat, and too little or even too much fluid can all play a role, so no single product is a 100% solution. The best thing you can do is not to wait for cramps: take your first dose before the start, then replace electrolytes steadily every hour. If you’re prone to cramping, run in very hot weather or sweat heavily, Endurolytes Extreme may be the better choice.
In our experience, this allows your body to make the best use of the glycogen stored in your muscles. If you do need a little energy, have a Hammer Gel 5–10 minutes before the start – but not earlier.
Yes. Drink plain water with the gel and the Endurolytes capsules at the aid stations; HEED needs to be mixed with water. We generally recommend 0.5–0.75 litres of fluid per hour, and up to 0.8 litres in hot weather.
Within 30 minutes of crossing the finish line. That’s when conditions are most favourable for your body to refill its glycogen stores; Recoverite provides complex carbohydrates and whey protein for this.
Yes. Our products are manufactured in accordance with US manufacturing regulations (21 CFR 111): every raw material used is tested for purity, potency, identity and integrity, and they are checked at every stage of production before they go on sale.
Try the servings in a long training session first, not on race day.
