Charity Miles

For walkers who would rather their miles helped someone else. Charity Miles is a free app that turns walks, runs and bike rides into money for a charity you choose, funded by corporate sponsors, and it has raised nearly $3 million since 2012. The newer route is your own pledge page, where friends and family can sponsor your everyday walking without you entering a race, with donations going through your charity's PayPal Giving page. It runs on iPhone and Android and can take walks recorded on a Garmin or Fitbit through Apple Health or Strava. Sponsor rates are not fixed, so treat each walk as a modest contribution.
