I did a triathlon 2 weeks ago, and these were being handed out at the finish:
Brand: Vanilla Hi Ball Energy.
Origin: San Francisco, CA.
Purchase Place: Maple Grove Triathlon.
Review: I saw a woman at the race dumping hers on the ground, so I didn't have high hopes. Turns out, she was 100% justified. This was horrible. It tasted like the worst possible version of La Croix water. The vanilla flavor was OK, but NOT in an unsweetened carbonated water drink. Gah. It needed about 50 grams of sugar to be drinkable. Disgusting. I only could manage a few sips of this.
Score: 1 out of 10.
