Three years ago I started running routinely. Not for a race, not for a bet — just to move. What I didn’t expect was that running would turn out to be one of the most instructive things I’ve ever done consistently, and not just physically. The lessons compound in strange ways. Here’s what I’ve actually learnt.

Consistency beats intensity, every single time

This is the one I had to learn the hard way. Early on I’d push hard on every run — treating each session like a test of will. The result was fatigue, a few minor injuries, and no meaningful improvement.

The shift happened when I stopped asking how hard and started asking how often. Running 40km a week at a comfortable pace, week after week, does more for your fitness than running 60km one week and collapsing the next. The body adapts to what it sees repeatedly. Showing up is the training.

You’re probably running your easy runs too fast

This took embarrassingly long to figure out. Most recreational runners — myself included for a long time — run their easy days at a moderate effort. Not hard enough to be a quality session, not easy enough to be genuine recovery. It’s the grey zone where plateaus live.

True easy pace feels almost insultingly slow. You should be able to hold a full conversation. Your breathing should be relaxed. If you’re slightly breathless, you’re already too fast.

Phil Maffetone’s formula — keeping your heart rate under 180 minus your age — is a useful (if humbling) calibration tool. When I first tried it, I was practically walking. That’s the point. Over months, your pace at that same effort improves noticeably. You’re not getting slower; you’re building the aerobic engine that makes everything else possible.

The aerobic base is everything

Related to the above: there’s a training concept called aerobic base building, and it explains a lot about why some runners plateau and others keep improving. The idea is simple — spend a significant chunk of time (8–16 weeks, or longer) running predominantly at low intensity, letting your cardiovascular and metabolic systems adapt before layering in any hard work.

What’s actually happening physiologically: your body grows denser capillary networks in muscle tissue, increases mitochondrial density, and strengthens the connective tissue that absorbs thousands of footstrikes. None of this is glamorous. None of it shows up on a Strava leaderboard. But when you eventually add tempo runs or intervals on top of a genuinely solid aerobic base, the adaptation is much deeper and the risk of injury drops significantly.

Without that base, speed work sits on a cracked foundation. You might get a quick boost, but it doesn’t compound.

Your gear matters less than you think — except when it doesn’t

Shoes are the one area where bad choices actually cost you. But the running industry makes this more complicated than it needs to be.

The biggest gear lesson: save carbon-plated shoes for race day and hard sessions. They’re genuinely impressive technology — the energy return is real. But wearing them for easy runs is counterproductive. The stiff plate masks natural fatigue signals, alters your biomechanics, and over time can contribute to calf and Achilles issues. More practically: they’re expensive and have limited mileage. Use them sparingly.

For daily training, you want a shoe that lets your foot work naturally, gives you enough cushion for the repetitive load, and — critically — fits your foot shape. If you have wider feet, brands like Altra and Hoka tend to be more accommodating than Nike (which runs narrow) or even ASICS (which runs on the narrower side). Spend time finding shoes that genuinely fit rather than defaulting to a brand because it looks fast.

Everything else — GPS watches, compression gear, specialised nutrition — is optional noise until you’re running serious volume. For the first year especially, none of it matters as much as just getting out the door.

Running teaches you something about patience that other things don’t

There’s a concept I keep coming back to: there is no compression algorithm for experience. You can read about aerobic adaptation, study training theory, optimise your nutrition — but the fitness only comes from the accumulated hours of actually running. The body doesn’t let you shortcut it.

This sounds obvious, but it runs counter to how we think about most things. In software, you can abstract and shortcut. In most professional work, clever thinking can substitute for raw time. Running doesn’t allow this. Three months of consistent easy running cannot be replaced by three weeks of hard running. The biology is stubborn.

What that teaches you — if you’re paying attention — is a certain respect for slow, compounding work. The kind where you can’t see the progress day to day but look back six months later and notice you’re running faster at the same effort, recovering quicker, feeling lighter on your feet. That’s not motivation or discipline. That’s just what happens when you show up enough times.

The mental component is undersold

Everyone talks about the physical benefits of running. Fewer people talk about what it does for your head.

There’s something particular about the rhythm of a solo run — especially the longer ones — that creates a kind of enforced stillness. No input, no screen, just you and a pace. Problems that felt urgent at 6am feel appropriately sized by kilometre four. Ideas surface that wouldn’t have appeared sitting at a desk.

After three years, running has become less about fitness and more about maintenance of something harder to name. Clarity, maybe. The ability to think in longer time horizons. Whatever it is, I notice its absence on weeks I don’t run more than I notice its presence on weeks I do.

Three years in, I’m still learning. The training theory keeps revealing new depth. The body keeps surprising. But the core of it is simple: run consistently, run mostly easy, be patient with adaptation, and respect the process. The rest tends to follow.
