RunClever Ratings© is the state of the art system to allow every standard run by an individual to be compared to every run they have ever done, and for that matter that anyone else has ever done. Millions upon millions of data points have been analysed, and an algorithm developed that can break down the impact of factors such as time running, distance covered, temperature, elevation and surface and how they affect one another over the course of your run. Based on this information, our system provides a rating for your run between 1 and 140, with 140 being the perceived limit of human physical ability.
