The Pace Calculator

This pace calculator has 2 modes. The straight line mode which calculates your time based on a constant pace over the entire distance and the Reigel mode based on the Reigel formula:
   NewTime = OldTime x (NewDistance / OldDistance)^1.06

To calculate what your time would be over a different distance simply follow the 4 easy steps below. The difference between this calculator and others is that it uses a JavaScript. Which means you can save this page to your hard disk and use it even off-line because all calculations are being performed by your browser it also means that it is platform independent (in theory!)... neat!

NEW: You can now create a small pace tag which can be taped to your watch bracelet. Click here.
