Welcome to AARP's Get Fit on Route 66. When you register for this free adventure, you embark on a nostalgic virtual journey down the legendary highway — The Main Street of America — made famous in books, movies, and on TV.

To help inspire you to be more active, you'll travel from Chicago to Santa Monica (2,448 miles) by recording exercise minutes. One minute of activity equals one mile on the route.

Time spent walking, biking, swimming, and playing tennis counts as exercise minutes, as do all activities that increase your heart rate and get you moving.
