Swim Time Calculator

This calculator will estimate a variety of swim times based on two previous swims.

For best results, use times for two swims that have a decent range (i.e. 100m and 1500m).

To begin, enter two swim distances and their corresponding times:

First Swim

Distance: metres

Time: hours minutes seconds

Second Swim

Distance: metres

Time: hours minutes seconds

(Optional) Target Predictions

Calculate this: yes no

TFD:

If enabled, predicted target times will be calculated using the TFD as defined above. 1.06 is considered a good rate of decay for triathletes. The expected improvement (EI) column denotes the potential gains that you could see should you train well!
