Running devices track speed and distance, with some using GPS for accuracy. They can also store information for progress tracking and offer features like mile updates and pace notifications for competitive runners.
People use many different devices to track their performance while running. Running devices are typically meant to track average speed and distance covered during the course of a run. Some running devices, such as stopwatches and pedometers, are quite simple and can only record the total time of a run and make rough estimates of speed and distance based on the average distance covered in a single step. Others, including some apps that can be loaded onto a smartphone, can sync with a global position satellite (GPS) system and record speed and distance more accurately. Many people also use running devices to store information each time they run so they can track their progress over time.
Distance tracking is one of the most common applications for running gadgets. People can track their workouts by tracking the distances they run on a daily or weekly basis. Endurance runners and people who train for marathons often focus on increasing the distance they cover each time they run. It’s often difficult to quantify progress if you don’t have an accurate idea of how far you’ve come. Crude devices that estimate distance by counting strides and making estimates based on the stride length estimate can be used for this purpose, as can more advanced devices that synchronize with GPS systems to provide more accurate distance measurements.
For many people, particularly those who run competitively, tracking speed is at least as important as tracking distance. Running gadgets for this purpose, again, range from the crude to the complex. If one knows the distance of their run, it is possible to simply record the time at various points throughout the run and calculate the average speeds as a function of time and distance. However, running devices with GPS systems can provide much more accurate information about your pace at any given point.
Some running devices are used to record information after a race, while others can be quite valuable while running, especially for those running competitively. Some running devices that track distance, for example, play a sound after each mile to update the runner on their progress. Others can notify the runner if his speed falls below a certain pace. This can be important for competitive runners who aspire to complete races in a specific amount of time.
