I get that 5k and 10k sound like nice even distances, so sure: start them wherever you need to on the track… but changing what should logically and progressively be 4-lap and 8-lap races into 3.75- and 7.5-lap races just feels arbitrary.
Looking for something better than “that’s just the way it’s been done since 1896” (I actually think that date is right, but besides the point…)
Happy Friday!
