these are brilliant

Taking these for London marathon training. If you like Vimto as I do this tastes exactly the same, it’s less thick that alternatives like Lucazade so easy to consume. Essential for runs over 8 miles.

I been purchasing these via a retailer who no longer stocks them and went in to panic mode as they are great for my long runs. I have a 1/2 and full marathon coming up in the next few month and with 20+ miles on a Sundays for my long runs I really needed these. They don’t upset my stomach like others I have tried and they get me through those hard miles. With these I am paying less than half the cost too that I had been paying the retailer.

Cheaper than most and kept me fuelled during long runs

Great tasting product worked for me before I went to the gym

These go bad really quickly - develop acidic gas and swell up in their little sachets after a couple of weeks stored in a cupboard at room temp... Best befores are well into 2026 so this shouldn't happen.

ProsPerfect for a team of say teenage footballersTaste is nicer than alot of gel'sEasy to openCan be carried in gym bags without bursting

23g of carbs delivered by maltodextrin so be careful if you're diabetic - it has a high glycemic index.The blackcurrant flavouring is really nice.It's quite sweet thanks to the sucralose - personally I'd be happier without this additive as I don't like the taste, but these are meant to be functional so I can live with it.Pack of 20 for £16, so 80p a sachet which is quite reasonable.
