Right now you can get a free sample of energy boosters known as Gel Blasts from PowerBar. This deal is only available for a very limited time -- who knows when supplies will run out.

To get the deal you must register on the site, which includes sharing your email, name, gender, year of birth, address, and how many hours per week you exercise. You also have to opt into its e-newsletter and agree to receive occasional offers and product promotions from PowerBar in the mail. The free Gel Blasts take 3-5 weeks to arrive.

Gel Blasts are energy chews that provide extra energy during moderate and high-intensity workouts like long runs or bike rides. Some of the Gel Blast flavors have a little caffeine to give you an extra boost.
