Week 5 is the one people warn you about. Up until now, the Couch to 5K app has been predictable: run a bit, walk a bit, repeat. Then suddenly Week 5 arrives and the structure changes every single day. And just when you think you’ve got the hang of it, it hits you with the infamous 20-minute non-stop run.
When I first looked at the plan, my brain went: “Twenty minutes?! Without stopping?! That must be a typo…” Spoiler alert: it wasn’t.
Day 1 – Getting started
- Total Time: 31:00
- Walking Distance: 0.90 mi → ~16:00
- Warm-up & Cool-down: 10:00
- Additional walking: ~6:00
- Running Distance: 1.29 mi → ~15:00
✅ About 15 min running, 16 min walking (10 min was warm-up/cool-down).
This run eased me in: three sets of 5-minute runs, broken up with walking. Manageable, but a good reminder that things were about to get more serious. The pace felt steady, and I even managed to enjoy parts of it.
Day 2 – Testing the waters
- Total Time: 31:00
- Walking Distance: 0.96 mi → ~15:00
- Warm-up & Cool-down: 10:00
- Additional walking: ~5:00
- Running Distance: 1.42 mi → ~16:00
✅ About 16 min running, 15 min walking (10 min warm-up/cool-down, 5 min mid-session walking).
Two 8-minute runs with a short break in between. A couple of weeks ago I’d never have believed I could run for 8 minutes straight. Now, somehow, I did it twice. Progress sneaks up on you like that.
Day 3 – The Big One
- Total Time: 30:00
- Walking Distance: 0.57 mi → ~10:00
- Warm-up & Cool-down: 10:00
- Additional walking: ~0:00
- Running Distance: 1.83 mi → ~20:00
✅ About 20 min running, 10 min walking (and here all walking is warm-up/cool-down).
This was the run: 20 minutes without stopping. No breaks. No excuses. Just running.
I won’t lie, I was nervous pressing start on the app. Half of me thought I’d never make it, but the other half was stubborn enough to try. The first 10 minutes felt okay, then came the mental battle. My legs started asking questions, my brain started making excuses, and I started negotiating with myself (“maybe 15 minutes is close enough?”).
But I kept going. Minute by minute, step by step. And then suddenly, there it was. The app buzzed, the voice said “Cool Down,” and I’d done it. 20 minutes, non-stop. No walking breaks. Just me, out there running.
By the end I realised it wasn’t just a physical challenge, it was a mental one. My body could handle more than I gave it credit for, it was my brain that needed convincing.
Finding Balance with Training and Work
One big change this week, I’ve shuffled my work schedule around. From now until the end of November, I’ve taken Monday and Friday mornings off work. That means no more 4:20am runs (unless it’s a run on a Wednesday shift).
This is already making such a difference. Instead of stumbling half-asleep out the door, running, and then dragging myself through a 12-hour shift, I can now actually focus on the run and recover properly. It feels so much more sustainable, and it takes away the constant mental battle of “when will I fit it in?”
Running three times a week is hard enough without also trying to do it on top of those marathon-length workdays. Giving myself this breathing space feels like a real win, and hopefully it’ll help me stay consistent as the runs get longer.
Extra Step: The Gym (Round Two)
My gym induction went well, no embarrassing accidents, no flying off the treadmill, no pushing the wrong button and launching a machine across the room. Success!
That said… due to work schedules, I’ve yet to actually go back. So for now, the gym has seen me exactly once, which is the same as the time I paid for a whole year and only made it to the induction.
The good news? I’ve managed to convince my wife to sign up too. So even if my gym attendance isn’t setting records yet, at least I’ve recruited a training partner. Maybe the two of us together will have more luck at making it through the doors regularly.
Reflections on Week 5
Week 5 was the turning point. I started the week thinking “there’s no way I can run that long,” and ended it proving myself wrong. It’s a reminder that training is about tricking your brain as much as training your body.
A few weeks ago, running for 90 seconds felt like hard work. Now I can run for 20 minutes straight. That’s progress worth celebrating.
And all of this is building towards something bigger. Every small milestone, every early run, every long day at work after training is part of the bigger picture, getting me to the start line of the 2026 London Marathon, raising money for the Meningitis Research Foundation.
Looking Ahead
Now that I’ve ticked off the big 20-minute run, it feels like the right time to move things up a notch. My end goal isn’t 5K! it’s the London Marathon! so next week I’m moving onto a 10K training plan.
C25K has been a brilliant starting point, but the 10K plan picks up exactly where Week 5 leaves off and pushes things further. The target now is to be running 10K, or around an hour non-stop, by the end of November.
It’s definitely a step up, but it feels like the right one. Hitting that milestone will give me a solid base to start my proper marathon training plan in December. One chapter closes, the next one begins, and the big picture is starting to come into focus.
Bring on the next challenge.
