Competitive athletes’ success can be determined by between mere milliseconds or even a millimeter! This means they must take into account every possible factor to ensure they have the best chances of winning, and that includes environmental differences between where they compete and train. Pace is a device that measures the environment for endurance athletes. The athlete measures the environment where they train periodically to build an understanding on what the athlete’s body is acclimated to. The athlete then measures the environment that they are competing in. Depending on their unique acclimation and what the race environment is, Pace suggests an adjustment in their pace/target heart rate to prepare for more harsh environments or to take advantage of more favorable conditions.
