Contact SwimRunPace
If a split table looks wrong, a unit is missing, or a formula does not match the source you train with, tell us. Calculation reports get priority over feature requests.
Write to [email protected] with the tool name, the numbers you entered, and what you expected to see.
What helps most
- A screenshot of the inputs and the result
- The source you are comparing against (a race result, a coaching book, another calculator)
- For unit issues: the country and the convention, e.g. US track 400 m versus 440 yd
What we cannot do
We cannot build a personal training plan or give medical advice. Injury, illness and nutrition questions belong with a physiotherapist, doctor or registered dietitian.
Feature requests
Distances and units are easy to add. New calculators are added when a formula can be stated precisely and tested; if you can point to the source, that helps.
What we do not collect
There is no account, no email capture and no training log. We cannot look up a past calculation for you, because it was never sent anywhere — if you need the number again, re-enter the inputs. That also means we cannot recover a result you forgot to save.
Response time
Usually a few business days, longer during race season.
Frequently Asked Questions
Can you add my local race distance?
Yes — send the distance in metres and the unit you race in.
Why does your VDOT differ from another site?
Small differences come from rounding the oxygen-cost curve. The method on this site follows Daniels' published equations.
