Love these!

By Mandy Midgett, Date 5/12/15

I love these on my long runs! The energy combined with reminding me of a sweet tart is just perfect for the hot, humid days I face during long runs! They are awesome!

I expected a chalky taste, but these have a good flavor and go down smoothly. I used these every day at my team camp, along with the electrolyte capsules, and I never cramped, despite the long miles and the Tucson heat.
