Easy to swallow, good energy
Good flavor, texture, and viscosity. Not too thick, easy to swallow while running. Recommended.

Reliable, Easy-to-Digest Fuel—Great for Runners
The SiS GO Isotonic Energy Gel Variety Pack delivers fast, stomach-friendly energy in a neat sampler format. The texture and flavor are notable—it’s one of the few gels I can take without needing water, and it powers me through mile after mile with minimal hassle

Best energy gels for long runs I’ve ever used.
These are so easy to use and the best energy gels I’ve bought so far for my long runs. Definitely a must have for half marathons/marathons.

Greta performing gel but super weird texture
These gels do get absorbed very quickly and help me from bonking with 22g of carbs without spiking your sugar and IMO do perform better than something like a Stinger Energy Gel that has 24g of carbs but 48% of that comes from added sugar. So here is where science vs practicality comes in since SIS Gels are simply bigger servings and take more room in your pockets and come out to $1.89 per serving in most cases which simply isn't amazing. Then factor in that the flavors of these are alright but they are more like the essence of flavor than anything substantial and the texture is simply gross and would be akin to eating goop maybe? Granted no one is eating gels for pleasure and on performance yeah SIS is 9/10, price 6/10, and taste and texture 4/10.

Favorite Gel after 9 marathons trying every other kind
Favorite gel and now the only one I use for long runs. I've ran 9 marathons and these are my holy grail. I used them for Boston this year and will never go back to the other ones. They are are more like a drink then something you have to choke down and seem to work quicker and longer than regular gels. They also don't sit in my stomach like a lump like a lot of gels do. I've tried all different kinds and these work lightyears better than any others.
