Race times at 12:20 per mile

Every finish below assumes you hold 12:20 /mi evenly the whole way — a useful yardstick, not a prediction. Real races fade; the pace calculator does the Riegel-adjusted version from a race you’ve actually run.

Is 12:20 per mile a good pace?

Honestly, the number matters less than the day it lands on. 12:20 /mi is an easy, base-building pace — and there is nothing wrong with that. Most of your week should feel this relaxed. If it’s your goal-race pace, most of your training should happen slower than this — the fastest way to a faster race is a pile of easy kilometres and a handful of hard ones, run on the right days. If it already feels easy, it’s a fine cruising pace to build your base on.

A pace chart can tell you the maths. It can’t tell you whether today is a day to hit it — that depends on your sleep, your legs, and the runs already behind you. That gap is exactly what Liftrun was built to close.
