My wife, Chrissy, is a distributor for XOWii. XOWii has a line of energy drinks that are low in sugar and caffeine, delivering sustained energy. You can learn more and purchase products at http://www.xowiixowiixowii.com/. The drinks have Kona Red cherry extract and Acai berry extract in them. I am experimenting with drinking them before and after my training runs. They might be a nice thing to add-on to my typical regimen of maltodextrin products (Hammer or GU).
