Runners love their GPS watches.
As a runner who grew up before the Internet and cell phones were ubiquitous, a Timex Ironman watch was my high-tech gear . As a result, I developed a strong awareness of perceived effort and self-awareness during my runs.
Technology can be wonderful guide for more effective training. Programming workouts into your GPS watch allows you to focus quality training at appropriate intensity (speed, pace, duration, or by perceived effort) by taking over tracking distance, pace, duration. No need to constantly check your watch, distracting you from engaging with what is important – pace control, breathing rate, perceived effort, and mental focus.
