I’ve used this product for all my marathon training and 3 marathons to date. It isn’t as sweet as some gels and I’m able to consume it successfully while running without undue digestive discomfort at the time. The tops are sometimes hard to tear off but otherwise no complaints- if you have to use gels, these are tolerable!
