Is 6:40 per km a good pace?
Honestly, the number matters less than the day it lands on. 6:40 /km is a steady, conversational pace for a lot of runners — often exactly where easy runs should sit. 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.
