Any honest best cycling energy gels review has to start with the thing brands avoid saying: for most rides, the cheap gel and the expensive gel do the same job. Carbohydrate is carbohydrate. What you are actually paying for at the top end is texture, digestibility at very high intake rates, and the confidence that comes with not experimenting on race morning.
We carry three. PICO FUEL for its maltodextrin-free formula and high carb load, Maurten for race day, and 4Endurance as the affordable option that turns up in half the jersey pockets on a Lagos club run. What goes in our saddle bags is the everyday one, because that is what a rider actually needs on an unplanned second lap of the Bravura loop.
Key Takeaways
- A 4Endurance 2:1 gel delivers 30 g of carbohydrate for roughly €2 at full price, against Maurten Gel 100’s 25 g for around €4, which is close to three times the cost per gram.
- PICO FUEL uses rice syrup, agave and real fruit rather than maltodextrin, with 41.8 to 47 g of carbohydrate per sachet, among the highest of any gel we carry.
- Maurten’s hydrogel technology is genuinely different, not marketing, and it is what allows intakes approaching 100 g of carbohydrate per hour without gut trouble.
- The glucose to fructose ratio matters more than the brand. Anything around 2:1 lets you absorb more per hour than glucose alone.
- Never trial a new gel on a big day. Texture tolerance is individual and the Foia climb is a poor place to find out where yours sits.
What Actually Matters in a Gel
Four things, in descending order of importance for most riders.
Carbohydrate per sachet is the headline number, and it ranges from 20 g at the low end to 47 g at the high end. Higher is not automatically better, it just means fewer wrappers in your pocket for the same hourly intake.
The glucose to fructose ratio is the part most riders skip and the part that changes what is possible. Glucose and fructose use different intestinal transporters, so combining them lets you absorb more than glucose alone. A ratio around 2:1 supports up to 90 g per hour, which is why nearly every serious gel now advertises it.
Texture decides whether you can actually take four of them in three hours. This is entirely individual and it is why a gel that a teammate swears by can be the one that makes you gag at hour four.
Cost matters more than gel marketing admits, because the correct number of gels to carry is more than you think, and a rider fuelling properly at 60 g an hour on a five-hour day is getting through eight or nine of them.
The Three We Carry
1. PICO FUEL – the everyday gel
PICO FUEL is one of our favourites and the one we reach for most. It skips maltodextrin entirely, building the gel from rice syrup, agave syrup and real fruit, which gives a slower, steadier release than the sharp glucose spike of a conventional gel. Each sachet carries between 41.8 and 47 g of carbohydrate in a 2:1 glucose to fructose ratio, which is a serious load for a single wrapper.
The texture is dense rather than runny, closer to a fruit purée than syrup. That suits some riders and not others, and it is worth knowing before you buy a box. For long inland days where the cafés are 30 km apart, the high carb count per sachet is the practical advantage.
2. Maurten Gel 100 – race day only
Maurten is the one we save for the days that matter. The Gel 100 is a 40 g sachet delivering 25 g of carbohydrate, 100 calories, 35 mg of sodium and six ingredients, with no colours, flavours or preservatives. What makes it different is the hydrogel: an alginate matrix that sets in stomach acid and carries the carbohydrate through to the small intestine, which is what allows intakes approaching 100 g an hour without the gut trouble that would normally cause.
That technology is real rather than marketing, and Maurten’s standing with WorldTour teams and marathon record holders reflects it. Two honest caveats. The texture is a soft jelly, closer to a set dessert than a gel, and plenty of riders never get on with it. And at roughly €4 a sachet it is expensive enough that using it for every training ride is hard to justify. Use it when the day is worth it, and trial it in training first so race morning is not the first time.
3. 4Endurance – the affordable option
4Endurance is the Portuguese staple, and it turns up in more jersey pockets on a Lagos club run than anything else. Their 2:1 gel carries 30 g of carbohydrate plus electrolytes, and the nduranz Nrgy Gel 45 carries 45 g, both at prices that make fuelling properly affordable rather than aspirational. A box of ten 2:1 gels lists at €19.99, and the range is frequently discounted well below that.
The model is direct to consumer with no middlemen, which is where the price comes from rather than any compromise in formulation. Products are WADA compliant and the brand sponsors Tudor Pro Cycling Team and the Slovenian Cycling Federation. For everyday training, and particularly for a week of back-to-back riding where you are getting through 40 or 50 gels across a group, this is the sensible choice.
The Cost Per Gram Question
The comparison brands prefer you not to make:
| Gel | Carbs per sachet | Approx. price each | Best used for |
|---|---|---|---|
| Maurten Gel 100 | 25 g | Around €4 | Race day and very high hourly intakes |
| PICO FUEL | 41.8 to 47 g | Mid range | Long days, fewer wrappers, no maltodextrin |
| 4Endurance 2:1 | 30 g | Around €2 at list price | Everyday training and group trips |
| nduranz Nrgy Gel 45 | 45 g | Around €2.50 at list price | High hourly intake on a budget |
Maurten costs roughly three times as much per gram of carbohydrate as 4Endurance. Whether that is worth it depends entirely on the day. For a Gran Fondo or a target event where gut comfort at 90 g an hour decides the outcome, yes. For a Tuesday in February on the Bravura loop, no.
What Goes in Our Saddle Bags
Every Velo Algarve rental leaves with a stocked saddle bag, and gels are in it alongside TPU tubes, tyre plugs, spare SRAM batteries and a mini pump. We stock the everyday option rather than the race-day one, for the same reason we do not put a time-trial saddle on a rental bike: the point is that it works for whoever is riding it.
The gels are there as insurance rather than a fuelling plan. On the inland roads north of Lagos and out on the Costa Vicentina toward Sagres, cafés sit 20 to 40 km apart and some close on Mondays and Tuesdays. Two gels in a saddle bag cover the gap between the route you planned and the café that turned out to be shut. Details of what else comes with a bike are on the full fleet spec, and what customers make of it is on our reviews page.
Frequently Asked Questions
What do you need to know about choosing cycling energy gels before you go?
Match the gel to the day rather than buying one type. Check carbohydrate per sachet, look for a glucose to fructose ratio around 2:1, and never trial a new gel on an important ride. Texture tolerance is individual, so test in training where a bad reaction costs you nothing.
Is Maurten worth the money?
For race day, yes. The hydrogel genuinely allows carbohydrate intakes approaching 100 g per hour without gut distress, which matters when the effort is long and hard. At roughly €4 a sachet against €2 for a comparable 30 g gel, it is hard to justify for everyday training rides.
What is the best value energy gel in Portugal?
4Endurance, which sells direct to consumer from a Portuguese site. Their 2:1 gel delivers 30 g of carbohydrate with electrolytes and the nduranz Nrgy Gel 45 delivers 45 g, both at a fraction of the cost per gram of premium brands, with WADA-compliant formulation and frequent discounting.
Why does the glucose to fructose ratio matter?
Glucose and fructose are absorbed through different intestinal transporters, so combining them lets you take on more carbohydrate per hour than glucose alone. A ratio around 2:1 supports intakes up to about 90 g per hour, which is why nearly every serious gel now formulates to it.
How many gels should I carry on a long ride in the Algarve?
Work from 30 to 60 g of carbohydrate per hour and subtract what you will get at café stops. On a five-hour day with one café stop, that is realistically six to eight gels. Carry two more than the plan requires, since inland cafés can be closed on Mondays and Tuesdays.
See Our Saddle Bag
Gels are the least interesting part of a bike rental and the one people are most glad of at 60 km. Every rental arrives with the saddle bag packed, the Garmin loaded with routes and the café stops marked, so the fuelling plan is already half made before you clip in.
