Best gels on the market. Not super sweet. Can be consumed without any water.My only complain is that some of the flavors are available only in Packs (like Vanilla, Pineapple and Pink Grapefruit). I really can't understand why.

Just wanted to say a big thank you for providing these bags. I have a work colleague who also collects the wrappers and sends them off and yet before I saw the sense I thought he was a bit 'bonkers' :-). However I have seen the light and encourage all my cycling friends to give me their wrappers so I can too recycle them!!!!! Brilliant idea, I just only wish everyone else would provide them too. Massive Thumbs Up Here

A good selection of flavours in the box, it has vanilla, I have not been able to purchase this flavour on its own.Was good value, this product is ideal for having on marathons and long training run's as it saves calling someone out to do a fluids drop-off.The only downside is opening them with damp hand's, end up using teeth, a larger 'top' to get hold of would be good.Have purchased these for year's and highly recommend them.

A real boost when you need it

I use the SIS double espresso gels when I need an extra boost either for significant hill climbs or towards the end of long sportives. I can’t say they’re a taste great but they’re reasonably palatable when you need an extra hit and exhaustion takes hold. There is quite a significant amount of caffeine in these and the recommended amount is two gels in a day. To be honest I have found two to be more than enough in any given ride and as mentioned only use these on the longer all day sportives or mountainous climbing routes. Being the SIS hydro variety you do not need to take water with them. If your a coffee fan then you should be fine with the double espresso taste.

Great flavour and texture

Very happy with the SiS gels. Personally find they sit well and are a good consistency not requiring water to take which is a real bonus. Flavour wise I got the Vanilla for the first time after trying some of the traditional flavours previously and was impressed. The SiS gels due to their consistency are also quite hydrating, great on warmer days. The only negative aspect is due to the more liquid texture they are on the bulkier side of gels but fit perfectly fine in shorts/belts I have. Highly recommend for people looking to start using gels.

Tastes a million times nicer that expected

These gels are never going to taste as good as cake. They serve a much more useful purpose than cake though. Training for a 10k swim and always got cramp at 5k. Decided to have one of these at the 4k point and kept going a few more km with no cramp. I've had other flavours back in my running days and this pineapple one is definitely my favourite. It's thick but not unpleasantly so. Sits okay in my stomach.

Train with same gels at running race course aid stations, heavier than other gels due to added water

It is a good idea to train with the same gels you'll be using during an actual race or event. Both the Rock and Roll marathon series and the Seattle Marathon use SIS gels for the on course aid stations. If you are participating in an event with on course support, check the event web page. These isotonic gels are premixed with water; this makes them easy to ingest quickly but also makes them heavier and bulkier than, for example, GU gels. SIS gels will now be part of my running training, both because they go down easily and because they are offered on course at future events.

Trusted friends !

I've been using these gels for years and they continue to be a favourite. Not the cheapest on the market but certainly very high quality and history of continuous improvement from SIS. Fuelld were super helpful and very quick to get them out the door and on the road to me, great service 👍

Very good

Different consistency (much thinner) than usual for Sis gels. I love raspberry flavour in general but this is a bit odd. I'd give it 5 stars but still not 100% convinced of the impact of the electrolytes. Difficult to work out the quantities and compare with other products

Very happy with this gel

I am really pleased with this gel. The texture is the best out of all the gels I've tried recently and it gave me a good energy boost. It was 28°c on my run so it was great to have a gel which slid down easily and refreshed me a bit at the same time.I still took this with some water because it was so hot.The only negative is that I had a small stitch for the next half a kilometer. I don't know if this is due to the gel, or the fact I took water with it-or if that was just co-incidence.I'll have to test some more to find out.But overall I'm really happy with this gel. I had the fruit salad flavour which was nice. Looking forward to trying the other flavours now.
