Discussion: per k time?

Does your team use per k times for running pace?

We always used minutes per mile paces, and it's one of the things I really have trouble changing. It's a mental barrier.

We used per k times for this race because the kilometer markers were part of our race plan, which works because we are used to per k times, as we often do 1000m repeats in practice. But on other workouts (long runs on the Monon, LTs, and tempo's), we almost exclusively use mile times.
