Swimming Expectations Calculator
The Swimming Race Expectations Calculator is based on work done by Peter Riegel.

Peter Riegel did basic formula for predicting race time. The formula is really simple as it essentially states that roughly speaking, a person's speed declines by around 6% when the distance doubles.

Peter Riegel's formula is: t2 = t1 * (d2 / d1)^1.06.

Peters work is relevent to most sports so it is can be applied to swimming, cycling and running.

If you put in a distance and time you have done the calculator will predicate the times you will be able to achieve for other distances.

#### Swim Calculators

• ##### Swimming Split Calculator
Used to calculate the number of laps and lap time to swim a given distance in a given time
• ##### Swimming Pace Calculator
You can use the Swimming Pace Calculator calculator to calculate the pace you need to swim at for a given distance. Results are given for 100 yards / 100 meters and Km per hour
• ##### Swimming Expectations Calculator
You can use the Swimming expectations calculator to calculate race expectation times on other distances based on given time over a given distance. These calcs are done based on work by Peter Riegel
• ##### Swimming Time Converter Calculator
Use this Calculator to calculate your time switching between yards and meters. This is useful when you need to compare times across pools of different measurement units such as indoor and outdoor pools. The Short course Indoor pool is 25yards where as long course outdoor in 50 meters.
