Units of Measure

Emily and I ran a 5k race today.

I’ve talked about this a lot elsewhere, but in the US, it’s standard to do splits in miles regardless of the race distance. So a 5k or 10k race has official mile splits. Usually there is zero signage in kilometers.

This race even had the clocks at each mile so you could check your pace.

The cadence of a 5k in the US ends up reliably being broken up into:

  • First Mile
  • Second Mile
  • Third Mile
  • Finish Sprint

This is how we tend to talk about, think about, train for, and pace ourselves during a race. I wonder if people in places where it’s all just kilometers think differently or pace differently.
