Runner's Calculator is an easy-to-use converter and split calculator specially designed and developed for runners. The converter converts all values at once, simultaneously. Just enter the value you want to convert from and the convertor immediately translates it to all other values in one sweep. Enter e.g. the finish time of a marathon and the average speed and pace, both metric and imperialist, will be calculated automatically along with all other finish times for a variety of classic running distances. The calorie counter uses scientifically designed models to estimate energy consumption as accurately as possible. Take the help of the calorie counter to reach your new weight goal or to know how much energy you need to compensate with after a strenuous race. With the split calculator, you can easily calculate negative splits for your future race to reach new heights of your potential. You may also save, print and share the calculated results easily as PDF.
