    What Are Endurance Supplements?

    Endurance supplements solve two problems that show up once a session goes past the hour mark: your muscles run low on stored carbohydrate, and you lose fluid and sodium through sweat. Both end the same way, with your pace dropping and the effort feeling far harder than it should. The American College of Sports Medicine recommends 30 to 60 grams of carbohydrate per hour for efforts of one to two and a half hours, and up to 90 grams per hour for longer events. That's hard to manage with normal food while you're moving, which is why purpose-made endurance nutrition exists.

    Types of Endurance and Hydration Supplements

    This collection has the main fuelling formats in one place. Carbohydrate drink mixes give you fuel and fluid together. Energy gels are compact and easy to carry, and energy bars suit longer, slower efforts where solid food sits well. Electrolytes handle hydration on their own, and caffeine supplements are there for a late-race lift. Most runners, cyclists, triathletes and hikers end up combining a few of these rather than relying on one product.

    How to Choose Endurance Supplements

    Start with how long and how hard your sessions are. For sessions over an hour, work out how much carbohydrate you'll take each hour and in what form, then add extra sodium if you sweat heavily or train through a humid NZ summer. If you're aiming for more than 60 grams per hour, choose products that pair glucose or maltodextrin with fructose, because the gut absorbs the two through different pathways. And test everything in training before race day. Our guide to the best supplements for running explains how these products fit together.

    Frequently Asked Questions

    • Endurance supplements are products that fuel and hydrate you during long or hard exercise. They include carbohydrate drink mixes, gels, bars, electrolytes and caffeine. They help you keep your pace when your body’s stored carbohydrate and fluid start running low.

    • The American College of Sports Medicine recommends 30 to 60 grams per hour for efforts of one to two and a half hours. For longer events, up to 90 grams per hour can help, using products that combine glucose and fructose. Start at the lower end and build up over several weeks of training. Check out our Carbohydrate Supplements collection for powders designed for high-carb fuelling strategies.

    • Most endurance athletes use a mix of all three. Drink mixes deliver carbohydrate and fluid together, energy gels are easy to carry and quick to take at higher intensity, but energy bars still work well at lower intensities where chewing is easier. Your choice comes down to the sport, the pace, the duration of the event, and what your stomach handles.

    • Gut problems usually come from taking in more carbohydrate than your body is used to, or from drinks mixed too strong. Your gut adapts with practice, so build your intake up gradually over long training sessions. Stick with products you’ve tested and never try something new on race day.

    • Caffeine is one of the better-researched performance aids for endurance sport. It can lower how hard the effort feels and help delay fatigue. Caffeine tolerance varies a lot between people, so try it in training first and start with a low dose. Most gels are available in caffeine and non-caffeine flavours, so you can create a fuelling plan that works best for your body.
