If you use Gu for your long workouts, this is an excellent deal. You get a good variety of Gu gels, Roctane gels, Chomps, and drink powders for far cheaper than if you bought them individually. You can't pick the flavors, but they send a lot of different ones so you'll probably get most of the ones you like and a few you maybe haven't tried before. I use them during my long training runs of over an hour as well as before races and during long races. The Gu & Roctane gels go down pretty well, especially if you drink a little water afterwards. The Chomps are a little harder to chew down as they can stick to your teeth, but if you like solid food on the run, they'll do the job. Some flavors of gel and Chomps have caffeine for an extra boost, while others are caffeine free. The beverages are mild and give you back some electrolytes, though the fizzing tabs have a habit of fizzing up out of my water bottle on the run, which means sometimes I'm wearing them as much as drinking them - I just mix them dilute and leave air space.
Bottom Line Yes, I would recommend this to a friend
