PowerBar, creator and leader of the energy bar category, is proud to be the Official Energy Bar and Energy Gel Sponsor of the Boston Marathon for the 15th consecutive year. The perfect tools for a marathon, both the Performance bar and PowerBar Gel feature a state-of-the-art-science carbohydrate blend. This becomes especially important to runners as they near Heartbreak Hill, which is why the PowerGel Zone will await them near mile 17. PowerBar encourages all runners to visit the new PowerBar.com — a comprehensive online destination for sports nutrition and training information, the new site also serves as a global communication tool for athletes and experts to engage and share experiences through user-generated content.
