Runner's PaceCalc FM

Runner's PaceCalc FM is the ultimate in iPhone Pace Calculators.
Designed by a runner for runners.
(Note: this is an update of an earlier version distributed on Itunes. See below for changes)

Not only can you calculate your pace for any distance, but you can get an idea of the position you would have had in one of many past populars races such as the Berlin, Chicago, Florence, London, Milan, New York, Paris, Prague, Rio and Rome Marathons, Ironman World Championships and others.
On a single screen you can modify distance, time, speed, pace and automatically Runner's Pace Calc will update the other parameters.

Some of the features:
- Units in Kilometers or Miles
- Variable distances from .1 to 1000.0 miles or kilometers, in 1/10th (MI/KM) increments.
- Prefixed distances (5K, 10K, 1/2 Marathon, Marathon, 50K, 50 miles, 100K, 100 miles)
- Comparision of time with real race data from many different races.
- Can vary distance, time, speed, pace, race or race position and other components will automatically be recalculated.
+ Change the pace -- total time, speed, and race position will be recalculated.
+ Change the distance -- total time will be recalculated (pace, speed and race position are not changed).
+ Change race or race position -- speed, pace, and total time (not distance) will be recalculated.
- Real race data for many popular Marathons, Ultramarathons and Ironman races.
- Easy to use tap and double tap gestures which allow you to skip quickly to desired values.

Not only will it find your pace, but it will answer all of your "What if?" questions that will pop up in your mind.

- What if I ran 5K in 25 minutues?
- What if I ran a marathon with the same pace?
- What if I ran a marathon with a pace 30 seconds slower per kilometer than my 5K pace?
- What pace would I have needed to be in the first 5000 in the Chicago Marathon?
- What position would I have had in the Kona Ironman with the same pace?
- What time and pace did the winner of Kona finish in?
- How does this compare to the winner of the Zurich Ironman?
- How does the winning time of the Chicago Marathon compare with New York?
