Compare Two Results


Race time improvement calculator guide

WeCovr's race time improvement calculator compares two race results to show time saved and percentage improvement.

What this running improvement calculator does

This page compares an older race time with a newer one and calculates the difference between them.

  • Shows time saved.

  • Shows percentage improvement.

  • Best used for the same race distance.

Why percentage improvement helps

A percentage figure makes it easier to compare progress across efforts, especially when the absolute time difference looks small.

Use matching race distances

Comparing a 5K with a 10K result will not produce a meaningful improvement percentage. Use like-for-like distances.

FAQs
Can this compare different race distances?

No. It is intended for comparing the same distance over time.

What if my new result is slower?

The same calculation still works, but it will show a negative improvement.

Is percentage improvement more useful than seconds saved?

Both can help. Seconds show the raw change, while percentage gives better context.
