the fastest 500 m lap, women

The fastest single lap of 111.12 m each woman has been timed at in an individual race. The same rules apply as on the men's page: the opening split of a race is never a lap, and a time that beats its own heat by an implausible margin is a timing fault rather than a performance.

the fastest single lap of 111.12 m a skater has been timed at, in an individual 500 m. The 500 m alone, because it is skated at near-constant pace and that is what makes a wrong lap detectable: a lap far under the skater’s own median in the same race is a split taken somewhere other than the lap line. The first split of a race is never counted — a 500 m and a 1500 m start half a lap out, and a 1000 m and a 3000 m start from a standstill, so it is not a lap anyone skated. A lap is also dropped when it beats the field's own median for that same split in that same heat by more than a tenth, or comes in more than 12% under the median lap of its heat: both are timing faults rather than performances, and without them this board reads 5 s. A whole 500 m row is left out when its opening split is more than 10% slower than the heat’s: a first timing point that fired late puts the missing time into a later lap, and that lap then looks like a record. Lap data covers 2003 onwards, 255 competitions, so a skater who raced only before that is not on it
