To use this converter, find the world record for the race you ran in the green column, and use that and your race time in the form below to calculate your performance index for that race. Type that decimal number into the "Your index" box below. Then read up and down the blue column to see performances that are equivalent to yours. Note: All record times are for females.

What is your performance index?
If the world record is hours, minutes and seconds and your time was hours, minutes and seconds,
your performance index is .

Uses: This is not a predictor; so if you just ran a 5:21 indoor mile, there is no indication that you would have run a 2:49 marathon that day. It is more useful for such comparisons as, "I can run an 800 in 2:30 and a half marathon in 1:40; which distance am I better at?"

Abbreviations: y = yards; in = indoor; est = estimated (no official world record for this distance); hs = high school; jr = junior; LW = lightweight
