Running in the Dark: Training Through Winter
What seven months of early-morning dark runs taught me about consistency, gear, and why discomfort is underrated.
By mid-October the alarm goes off into complete darkness. By January you’ve forgotten what a sunrise looks like from the outside. If you run before work in the UK, you spend roughly seven months operating in conditions that would give a sensible person pause.
I’ve done this for four winters now. Here’s what I’ve learned.
Gear matters, but less than you think
The first winter I bought all the wrong things. Gloves that were too thick and made my hands sweat. A headtorch so bright it blinded me when I looked down at uneven ground. A jacket that blocked wind but turned into a sauna after three minutes of running pace.
After four iterations, my cold-dark-run kit is:
- Headtorch: Petzl Actik Core. 450 lumens, rechargeable, light enough to forget it’s there
- Gloves: Cheap running gloves from Decathlon, two pairs. When one pair is wet, the other is dry
- Jacket: Inov-8 Raceshell. Blocks wind and light rain, packs to nothing, breathes enough
- Shoes: Whatever I’d run in anyway. Waterproof trail shoes sound good in theory; in practice they’re hot and heavy
The real gear upgrade is accepting that you will get wet and cold sometimes and this is not an emergency.
The psychology of showing up
Dark runs are psychologically harder to start and psychologically easier to finish. The hardest part is the gap between the alarm and the front door. Once you’re outside, it’s just running — and at 5:30am in November there’s nobody about, no traffic to dodge, no social performance to maintain. Just you and the sound of your feet.
I’ve started thinking of winter running as the most honest form of the sport. Nobody is watching. There’s no scenery worth photographing. There’s no excuse to slow to a walk for a better view. You’re doing it because you said you would.
What it does for the rest of the year
I ran my first sub-4-hour marathon last spring after a winter of consistent 5am sessions. I don’t think the early mornings were the cause — but the consistency they forced was. You can’t run on enthusiasm alone. Enthusiasm is weather-dependent. Systems aren’t.
The other thing winter running does is recalibrate your relationship with discomfort. By the time April arrives and the mornings are light and mild, a hard workout feels like a reward rather than a chore. The bar for “this is unpleasant enough to skip” has moved substantially.
My next race is in October. The training starts in earnest next week. The dark will be back before it’s over.
