Top product for mid ride refuel
Excellent product great taste, nice texture and high quality product - used on multiple long day rides for Enduro MTB including Ard Rock. Unkike gels and most energy bars you can genuinely eat these on the move, they make no mess and weight to carb level is decent. These are now my go to for my hourly top ups in between proper feeds and provide a quick energy boost when you need it.

Great for cycling. Not so for running
Have used cycling and running. 100km+ on bike and 35km+ running and I can confirm that these are great for chewing on, on the bike but are not great when running. They are too chewy and hard to digest. I would 100 percent recommend for cycling but not running. Good value for money and really do help increase your carbs and energy in a ride. Not sure what the sugar content is but they are quite sweet.They are very easy to use on the go.

So much better than a gel
Having tried a number of different gels (and not found any that are easy to consume and agree with my stomach, these have been a relevation. They are more like jelly cubes (for making jelly with) and are easy to eat, not sickly or sticky. Each energy chew has 2 sticks of 3, I eat a third at a time, and they are then easy to fold the packaging over and put them away while you eat. I use them for cycling and hillwalking and they're some much easier to handle than gels, allowing you to eat part and spread it out - I always ended up taking the whole gel to save on mess even if I didn't want any more.Once I've started to eat one, it gives me the energy I need to keep active, helping me to concentrate and complete the activity. They are suitable for vegans, meaning I can keep one in my rucksack in case someone in my group needs some energy, without worrying about whether they can have it.Overall, a great product that does what you hope it will do. And did I mention it's better than a gel??!

easy to eat while running
Easy to chew/swallow mid marathon! And the taste is OK too - like a chewy sweet, but softer and not as nice

Tipo gominola, está buena
No se si es sicológico o que realmente funciona, el caso es que cuando lo utilizo me da un plus muy alto.

Great alternative to gels .. tasty and easy to take
If you prefer something more solid to chew instead of liquid gels, this is definitely the way to go.The taste is very good and it’s easy to consume during activity. So far, I haven’t had any issues with my body not tolerating the ingredients, which is always important for sports nutrition.A great option for anyone looking for a reliable and tasty energy source.

Une excellente alternative aux gels, facile à mâcher en effort !
J'ai testé les barres SiS Beta Fuel (format chews/pâte de fruits) pour varier l'apport énergétique sur le vélo et l'endurance longue, et le résultat est très convainquant.Les points forts :- Texture idéale en effort : Contrairement à beaucoup de barres trop sèches ou difficiles à mâcher quand le rythme est élevé, la texture gel/pâte de fruits est très facile à ingérer et ne colle pas aux dents.- Format pratique : La barre se découpe facilement en portions (souvent deux blocs dans le sachet), ce qui permet d'étaler la prise de glucides progressivement sans tout manger d'un coup.- Très digeste : Grâce à la formulation Beta Fuel (ratio 1:0,8), l'assimilation est ultra rapide sans aucun inconfort ni lourdeur sur l'estomac.- Goût très réussi : Le parfum est bien dosé, gourmand sans être écœurant, même après plusieurs heures d'effort.En résumé :C'est le produit parfait si vous en avez marre d'enchaîner uniquement des gels liquides ou des boissons. Un concentré d'énergie ultra efficace, facile à consommer en roulant ou en courant. Un incontournable de ma nutrition sportive !
