If your running watch is screaming that you are going too fast but you feel like you cannot go any slower without walking, here is the secret: walk. Stop chasing a pace that your body is not ready for and switch your focus to your heart rate instead. This one change will stop the struggle of the “grey area” and actually make you a faster runner in the long run.
I hear this from athletes constantly. It is even a sore point at home; my partner insists she “just can’t go any slower.” If you feel like Zone 2 is an impossible tightrope between a shuffle and a sprint, you are not alone. But here is the coaching reality: you are likely looking at the wrong numbers.
The Problem With “The Grey Area”
Most runners struggle with Zone 2 because their zones are simply wrong. Traditional pace-based zones are usually just a percentage of your threshold pace. As you get slower, your Zone 2 actually moves further away from your threshold in real time.
Let’s look at the math. If you hit the average parkrun time of 35 minutes, a standard calculator might tell you your Zone 2 pace is between 7:47 and 8:45 per km. For 99% of people, that is a frustrating “grey area.” It is not quite a jog, it is not a walk, and it feels awkward.
Even for me, the numbers can be liars. My personal threshold is around 4:00 per km (cue the trumpets). In that same calculator, my Zone 2 would be between 4:27 and 5:00 per km. In reality, I would find that way too hard for a true easy run.
Stop Running to Pace
My biggest piece of coaching advice is this: Stop using pace to measure your easy runs. Your heart rate is the only true metric of how hard your body is actually working. Sure, there is a bit of a lag when you speed up, but we can work with that. When you focus on heart rate, you can adjust your effort instantly:
- Heart rate creeping up? Slow down or walk.
- Hitting a steep hill? Walk it.
- Catching a nice descent? Pick up the speed.
Yes, I am a running coach telling you that you do not have to run all the time.
I recently coached a runner who could not stay in her easy zone to save her life. I gave her a simple rule: if the heart rate goes over the limit, you walk. It felt like a blow to her ego at first, but it stopped her nagging knee and hip injuries. It gave her the confidence to go further and run more often.
The result? In 12 weeks, her 5K time dropped from 38 minutes to 32 minutes. She gets annoyed at the walking sometimes, but it enabled her to actually enjoy running again.
The Science of the “Walk Break”
You can use walking to test your fitness. The quicker your heart rate drops when you slow down, the better your aerobic system is working. This is because your body does not have to scramble for oxygen for as many processes.
The more you stay consistent with this, the faster your “easy” pace becomes. Every time you swallow your pride and walk, you are training your heart to recover faster. What starts as 2 minutes running and 1 minute walking will quickly become 3 minutes running and 30 seconds walking.
Play the Long Game
Time on your feet is the best way to become a better runner. Going slower reduces fatigue, which means you can show up for your next session feeling fresh rather than knackered. If I had to kill myself every time I stepped out the door, I would not want to go out at all.
I know it feels counterintuitive. Your ego wants you to run, but your body needs you to slow down. By embracing the walk and ignoring the pace on your wrist, you are not being a “slow runner.” You are being a “smart runner.”
So, next time your watch starts shouting? Smile, take a walking break, and remember: you are playing the long game while everyone else is just getting tired.
