MapMyFitness is teaming up with makers of the popular “workout beverage” to launch a new challenge. When you workout at least 4 times a week and hydrate with Propel Workout Water or Propel Powder, you could win an Under Armour gift card. All types of workouts count and the challenge runs through August 6th.

Once you enter the challenge, workouts done on MapMyFitness, MapMyRun, MapMyWalk or MapMyRide will automatically be entered onto the challenge board. You do have to manually enter those Propels you chug on the website, though.

Propel, for those who don’t know, is touted as the “perfect hydration for the way you workout.” It comes in nine light flavors, and has all the right vitamins and antioxidants you could need, and no sufficient calories to worry about.

So, are you in?
