Log a mile this Sunday using a special running app, and Nike will donate to Austin-based Marathon Kids.

Marathon Kids is one of three beneficiaries of the “Find Your Fast” Challenge, along with a nonprofit in Brazil and one in China. The home-grown program encourages kids to run one or more marathons, cumulatively, during the course of the school year, and lead healthy, active lives.

Anyone can participate in Sunday’s event by using the free Nike+ Running App to record their mile. Nike will cap its contributions to the three beneficiaries at $100,000.

To join, go here.

You’ll be hearing more about Marathon Kids from Nike. Earlier this month, the sports gear giant announced a two-year partnership with the local non-profit, which has encouraged elementary-aged children to run since it was created in 1995. Nike will provide marketing and communications support, plus incentives like T-shirts, shoe laces and bracelets, for kids who reach milestones in the program.
