Too sweet for my taste.

It did fuel my long 100+ mile rides, but was overly sweet to me. To the point it was just hard to drink. And on a hot day, wasn�t a good combination.

Sticking to GU Roctane.

Thank you for your feedback.

Good product. Using it for before and after rides.

Have used this mostly after intense rides on Zwift. Especially the big climbing rides. Plan to take it with me when I start riding outside again. Also plan to try it as a pre-ride hydration drink. Tastes good with no after taste. Good thirst quencher after working outside in the yard as well. Any activity that generates a lot of water loss.

Thank you for your feedback.

The only electrolyte drink to use

I've used EFS over several disciplines, swimming, cycling, Endurance horse racing. One drink, all disciplines. Easy to mix and stays soluble. A flavor for anyone.

Thank you for your feedback.
