He's live from THE PLAYERS and has more on HOW it works...Chris? 3 00-0521-27PKG Step by step, hole by hole, every person at TPC Sawgrass this week that has a smartphone has the ability to help raise money for local and national charities.It's the Humana Walk-It challenge powered by Charity Miles. Once you download the free Charity Miles app and sign sign in, you are all set. SOT For every mile that people walk, 25 cents is donated to national charities. In addition to that, Humana will donate up to $20,000 to give back into this community. VO With many charities to pick from, you can select where the money you raise will go. Last year, THE PLAYERS had the most miles walked by fans at any PGA Tour event during the year. Because of that, Humana built a playground a few weeks ago for kids off of University Blvd. SOT 17:38 I was just there on site helping build that playground in the Sable Palms apartments here in Jacksonville.It was incredible, the children were able to develop and design their own playground.And we all came together to build that, THE PLAYERS, Humana, and the community to build that. VO Humana's goal with the Walk-It challenge is to encourage people to help give back. Many fans have already downloaded the app and have been using it out here this week, so every time a foot hits the ground, money is being made. 3 Don't forget to download Channel 4's players app for free ... for your apple or android devices.
