Best energy gels for trail running

Introducing nutrition to your running practice is one of the most beneficial moves you can make. Energy gels are an outstandingly efficient source of mid-run carbs which will help you reach marathon lengths and beyond.

Because your glycogen stores are finite, there's no way to run for much longer than a couple of hours without 'bonking', which is a frankly hilarious term for 'hitting the wall', running out of energy completely. This isn't a problem if you're going for a casual 5k, but any ambitious runner is likely to try out some gels at some point.

High 5 energy gel getting tested by LFTO

There are dozens of options on the market, but only a handful that won't make you scrunch your eyes and shake your head when you tkae them. It's tough to make something so nutritionally concentrated taste good, but the very best energy gel brands managed to pull it off.

Best Gels for a caffeine boost – Nutrition X Energel

We've spent the last few weekends destroying our calves on long demanding trail runs and eating gels as we went. This list contains the ones that we would pack for an ultra marathon. Effective, easy on the stomach, and most importantly, tasty.

Our list also contains gels with a variety of added extras. Beyond dense carbs, some gels include caffeine for an extra mental and physical boost, while others might contain electrolytes to help the body remain hydrated.

How we tested these energy gels

Thankfully, more than one member of the LFTO team loves a bit of trail running. We've spent this summer hitting the occasional half marathon and enjoying long runs on the weekend, gradually going through gels and narrowing it down to our favourites.

One of our biggest weekends of gel testing was at Love Trails trail running festival in Gower, Wales. Kate Milsom and Milo Wilson (hi there!) spent the weekend racking up mile after glycogen-sapping mile, and they sustained themselves with a huge pile of assorted gels and bars.

We not only tested these in practice, but we've also used them to recover some energy after a hard run, which gave us more time to consider the flavours and make a few notes. So, without further ado, here's the scoop on our 6 favourite gels for all your running needs.

What to look for in an energy gel

Best energy gels for running

Carbohydrate Content: Check the carbohydrate content per serving. Most energy gels primarily provide quick energy through simple carbohydrates, but you can look for gels with a balanced mix of simple and complex carbs to sustain energy levels.

Electrolytes and Nutrients: Some gels include added electrolytes like sodium and potassium to help maintain hydration and prevent cramping. Consider gels with additional nutrients like amino acids or caffeine if they align with your specific energy needs – be sure to give caffeine gels a test run for your stomach before you use one to compete.

Taste: Taste preference is subjective. Experiment with different flavours to find one that you enjoy and can tolerate during runs. Most brands offer a variety of flavours, but they're usually within the same vein. So find a brand whose style you like, whether its sweet and fruity or straight condensed coffee.

Texture and Consistency: Look for gels with a texture that suits you. Some gels are more liquid, which makes them easier to take quickly, while others are thicker, which you might prefer in the mouth. Consider whether you prefer a gel that can be consumed without water or one that requires hydration to aid in swallowing.

Digestibility: Opt for gels that are easy on your stomach. Some runners may experience gastrointestinal discomfort with certain ingredients. Unfortunately, there's only one way to find out which gels give you grief...

Packaging and Portability: Convenient packaging is crucial during a run. Choose gels that are easy to open and consume without making a mess. Of course, compact gels are more efficient, but you'd be hard pressed to find a gratuitously large energy gel.

Energy Release Rate: Consider the rate at which the gel provides energy. Some gels offer a quick burst of energy, while others provide a more gradual release. Choose gels that align with your energy needs and the duration of your run.
