Runner's Calculator III

The Runner's Calculator III aims to allow the athlete to measure their performance to plan your workouts and your runnings.
Regarding the first version, some minor improvements and adjustments were made based on user reviews.
Through a very simple and intuitive interface are provided the following calculations:

* Pace: Calculation of pace in min/km or min/mi for a given distance and time.
* Total Time: Calculating the total time for a given distance and race pace.
* Target Time: Calculate the expected time to run a distance, based on time from another distance already ran. For example, based the time of the 10K, you can estimate your time to finish a marathon.
* Body Mass: Calculation of body mass index.
* Estimated VO2: Calculation of VO2 estimated based on recent time for the 10K.
* Lap Tables: Calculation of accumulated time on each lap, considering the average pace, to run a specific distance.
* Tennis Shoe History: Store the distance to a particular tennis shoe. It is not a rule, but to have a reference considers that the average lifespan of a tennis shoe is 500km (310mi). There are models that can pass the 800km (497mi), depending on the materials and technology used in their manufacture.
* Conversions: distance, pace and temperature.
