I love getting to know a city on a walking tour. But if you want to see the scenery move by more quickly, City Running Tours provides both exercise and sightseeing, notes the Intelligent Travel blog.
Each tour includes a T-shirt and souvenir photo. Pricing is like a rental car: $60 for the first six miles, and $6 a mile after that.
Available cities: San Diego, Charleston, Chicago, New York, Washington, D.C., and Austin.
