Learning Center: Selecting Speed & Distance Monitors


Select Speed and Distance Monitors

Key Benefits

  • Know how fast you are running (pace or speed)
  • Know how far you have run
  • Preset distance marker for automatic lap/split times

The Basics

  • A speed and distance monitor acts as a speedometer and odometer during your run; it provides your running speed and distance traveled.
  • There are two types of speed and distance monitors: GPS or Foot Pod Accelerometer
  • Strengths of GPS units:
    • Works for other activities such as cycling
    • No need for calibration, which allows easy use among spouses or friends
    • Better than 99% accurate in environments with clear view of sky
    • Potential to chart the course that has been traversed
  • Weaknesses of GPS units:
    • Accuracy decreases when a clear view of the sky is not available
    • Some models do not account for changes in elevation, which results in reduced accuracy
  • Strengths of Foot Pod Accelerometer:
    • Over 97% accurate regardless of view of the sky
    • Calibration of foot pod ensures individual accuracy
    • Measures actual distance of foot travel regardless of elevation change
  • Weaknesses of Foot Pod Accelerometer:
    • Less than 5% percent of the population has unusual foot-strike mechanics, which reduce the accuracy of a foot pod
    • Must be calibrated for use by others and then recalibrated for yourself

Key Features

  • Displays speed in pace (min/mile or min/km) or speed of distance traveled over time (miles/hr or km/hr)
  • Displays current distance traveled
  • Records predetermined distance laps/splits automatically
  • Recalls average pace for laps/splits
  • Predicts finish time based on event distance and pace data
  • Charts the course that was traversed
  • Uses waypoints to chart key points for backtracking or future runs
  • Downloads speed and distance data to a computer
  • Is compatible with heart rate monitors with use of one watch
