It's no secret that properly fuelling your runs, nailing your hydration and taking in the right nutrients to maximise recovery can make a huge difference to your performance – both in the short and long term.

Much of a runner’s nutritional needs can – and should – be met through natural, whole foods as a part of a well-balanced diet, but engineered sports nutrition products, with their precise nutrient profile and tailored delivery, are also a piece of the optimum nutrition puzzle.

However, with a vast array of products – from gels, chews and electrolytes to energy bars and protein powders – it can be tricky to know where to start.

How we test

We enlisted four leading sport nutritionists and dieticians to evaluate over 150 sports nutrition products across eight categories. They judged each based on their nutritional make-up, quality of ingredients and formulation, with only those that best met runners’ needs going forward for further testing. Then, in the Runner’s World Lab, our expert testing panel – made up of our editors and other experienced runners – rated each product on flavour, aroma, texture and ease of use, as well as the impact it had on performance, where relevant.

To avoid brand bias, packaging and other identifiable elements were removed and preparation instructions were followed to the letter. Feedback from our nutritionists and testers was then analysed and each product was awarded an overall score.

With a creamy texture and chocolate flavour, ON’s whey powder went down a treat with our testers, who thought it tasted like a milkshake. Alongside 24g of protein, each scoop delivers 5.5g of naturally occurring BCAAs to aid recovery. Blend with some peanut butter and a banana to up the carbs and fats.

If glugging a thick shake after a tough session doesn’t appeal, try whey isolate. It has a water-like consistency that’s easy to get down when you can’t stomach anything heavier. Our testers loved the sherbet flavour and said it was like drinking fruit squash. The ingredients list is free from artificial flavours, too.

If you’ve written off vegan protein as chalky, Form’s blend may change your mind. Our testers rated its velvety-smooth texture and natural chocolate-hazelnut flavour. Aside from a huge hit of protein and a full spectrum of amino acids, each scoop dishes up 5g of BCAAs for recovery and digestive enzymes to prevent bloating.

Designed to ‘taste and feel just like a dairy shake’ – this didn’t disappoint. Our panel heaped praise on the creamy consistency (even when mixed with water) and subtly sweet banana flavour. The pea, pumpkin, brown rice and soya blend also ticks the nutrition boxes, providing all nine essential amino acids.

Looking for an all-round- good-for-you post-run recovery option? This is made with just a handful of natural ingredients: pea, rice and sunflower protein, coconut sugar, raw cacao and banana – that’s zero additives, artificial flavours or sweeteners. It’s also a complete protein source and each serving also packs a good hit of carbs to replenish glycogen post-run.

Loaded with 21g of muscle- building protein, plus a sufficient smattering of carbs, our winner will help your battered body to rebuild and repair post- run. It triumphs on the flavour front, with a gooey caramel layer, crunchy pieces and a sweet white chocolate casing. The texture isn’t dry and there’s no dusty aftertaste.

This salted caramel bar satisfies your sweet cravings. Think malty chocolate, chewy salted caramel and butterscotch pieces – a ‘heavenly combination’ in our testers’ opinion. The soft, squidgy texture also proved popular as a refreshing change to other bars. It offers 20g of protein to kick-start your post-run recovery, it’s low in sugar, but delivers 6g of fibre to keep you going until your next meal.

This plant-based offering wowed our testers with its ‘indulgent’ chocolate bar taste and texture. Combining sweet milk chocolate and crunchy, salty peanuts, the taste was likened to a Snickers, with testers admitting they would happily chomp on it as a treat. It packs 15g of plant protein – a soya, rice and pea blend that constitutes a complete protein – to aid muscle recovery and a hefty 21g of carbs to replenish your glycogen stores.

With 20g of protein, this is the biggest hitter in our plant-based category. Along with the protein, its relatively high (healthy) fat count and dense texture mean it will help keep you fuller for longer. The salted caramel flavour, with hints of tiramisu, is subtle and not overly sweet, and it ticks the ‘complete protein’ box with its soya, pea and pumpkin blend. As with all SiS products, it’s Informed Sport-approved and suitable for drug-tested athletes.

This is the favoured fuel of elite athletes, including Eliud Kipchoge, so it’s no surprise that it scored highly with our panel. Its unique hydrogel technology helps to speed and increase carbohydrate absorption, while reducing the risk of digestive issues. Our testers noted a tangible difference in performance, boosting energy mid-run – they also felt it was gentle on their stomachs. The consistency is thicker than many of its competitors, but it’s water-based so quickly dissolves on your tongue.

Our panel raved about the gooey, melt-in-your-mouth texture – and approved of the moreish fruity flavour. Each pack contains six cubes, each offering 7g of quick-acting carbs to replenish your energy stores and, unlike many gels, they weren’t sticky or messy.

This is formulated with a 1:0.8 blend of maltodextrin and fructose to help you absorb more carbs per hour without upsetting your stomach. Plus, it features active ingredients such as L-citrulline and L-arginine to help fight fatigue. The neutral syrupy taste and runny consistency went down well with our testers, who found it easy to knock back on the run.

A big-hitter with 40g of carbs and 200mg of caffeine, plus nootropic ingredients (linked to brain function) including taurine, citicoline and L-theanine to combat mental fatigue. Research into nootropics is still in its infancy, but our runners felt the gel aided their performance and helped them stay focused. It has that optimal blend of maltodextrin and fructose to avoid digestive issues and our panel enjoyed the smooth texture, but the sharp citrus flavour wasn’t for everyone.

Our turbocharged champ packs 80g of carbs per serving for a hefty boost. Unlike many energy supps, which provide a 3:1 glucose to fructose ratio, this has the magic 1:0.8 blend of maltodextrin to fructose. This allows your body to process more carbs per hour with less risk of GI issues. The powder dissolved quickly in water, with no lumps, and the subtle orange flavour made it very drinkable for our testers.

While most energy bars are oat-, flour- or nut- based, rice does the heavy lifting here and, according to our experts, this is great for those prone to gastrointestinal troubles as it can be easier on the stomach. It’s high in carbs for energy, but low in fibre, fats and protein to prevent on-the-run digestive discomfort. The chewy texture and rich chocolate flavour also impressed our taste testers, who described it as just like a delicious rice crispy treat.
