An electronic device ( 10 ) comprising a location determining component ( 12 ), such as a global positioning system ("GPS") device, a pedometer ( 14 ), and a computing device ( 16 ) is operable to determine a distance traveled by a user. The pedometer ( 14 ) is operable to sense a step taken by the user, and the location determining component ( 12 ), when accessible, is operable to determine a distance between two positions and supply such information to the computing device ( 16 ) for continuous calculation of an accurate step size of the user. When the location determining component ( 12 ) is inaccessible, the computing device ( 16 ) determines the distance traveled using the accurate step size information. In additional embodiments, a housing ( 132 ) is provided for storing a location determining component ( 112 ), a pedometer ( 114 ), and a computing device ( 116 ), and an accelerometer ( 242 ) is provided for also determining the step size of the user. A computing device ( 216 ) is then operable to calibrate the step size of the user as determined by the accelerometer ( 242 ).
