What’s it really like to start running in your 40s? Well, it’s harder than when in your 20s, but it’s certainly worthwhile!
The Midlife Mile

How It All Started (Or: Midlife Crisis, but in Trainers)
At 44, I hit a wall. Not literally, although with my coordination, that wouldn’t have been surprising. No, I hit one of those invisible walls where your body’s making passive-aggressive comments, and you start wondering how many more years you can get away with “I’ll start Monday”.
I was carrying more weight than felt comfortable, mentally foggy most days, and permanently knackered. The idea of running had been rattling around in my head for a while, though I’d always assumed it was a young person’s game — you know, for people whose knees haven’t met gravity yet.
But one day, between the self-loathing and the second packet of crisps, something shifted. I thought, “What if I gave this running thing a proper go?” Not to become some shredded Instagram bloke, but just to feel better, lighter, maybe even a bit proud of myself again.
Honestly, I was terrified. Every excuse came up: too old, too heavy, too unfit. But a few mates had started running and lived to tell the tale, so I figured I’d at least survive the first attempt. I dug out some ancient trainers from the back of the cupboard (I think they pre-dated the iPhone), chucked on whatever passed for activewear, and shuffled out the door.
It was awkward. It was wheezy. It was short. But it was a start.
And something odd happened: it didn’t make me feel worse. It actually helped clear my head. Those short jogs became a chance to step away from the noise of everyday life, breathe fresh air, and process things without a screen in front of me.
Each week, it got a bit easier. I didn’t magically become a gazelle, but I started to feel stronger — physically and mentally. Running became less about punishment and more about momentum. I was no longer chasing a six-pack; I was chasing headspace, confidence, and the smug satisfaction of doing something hard on purpose.
Running After 40: It’s Different, Alright
Starting anything new in your 40s is a laugh, especially when it involves pounding pavement instead of sitting down with a nice cuppa. But running? That comes with its own set of quirks.
Your body isn’t quite the same as it was in your twenties. You might discover muscles you forgot existed — usually because they’re now screaming at you. Joints can get grumpy, old injuries reintroduce themselves, and flexibility? That seems to have packed up and left years ago.
Recovery also becomes a slow-motion affair. What a 25-year-old shrugs off in 24 hours might have you walking like a cowboy for the better part of a week. Which means rest days are no longer optional — they’re sacred.
Then there’s the head stuff. It’s easy to feel like you’ve missed your window, that this is a young person’s game. But honestly? That’s nonsense. You’re still allowed to take up space at the start line, even if you’re also taking up a bit more room in your running top.
The trick is to set goals that suit you. Don’t compare yourself to some Lycra-clad YouTuber who “accidentally” ran 10K before breakfast. Focus on where you are, and go from there. Baby steps still count.
Gear That Doesn’t Make You Look Silly (and Might Save Your Knees)
Now, I’m not saying you need to drop a fortune before your first run, but some kit is actually worth the investment — especially if you’d like your knees to continue functioning.
Start with proper running shoes. Not fashion trainers. Not whatever’s at the bottom of your gym bag from 2012. Get a pair that suits your foot type and gives you support where you need it. Most decent running shops will watch how you walk and recommend something that won’t destroy your joints.
As for clothing, breathable gear makes a huge difference. Moisture-wicking fabric is your friend. It keeps things dry, helps with temperature, and reduces chafing — which, trust me, is not a rite of passage anyone wants.
If you’re running in the early morning or evening (or you live somewhere with weather), think about layers and visibility. Reflective gear isn’t just for safety nerds — it’s how you avoid becoming a cautionary tale.
You might also want to grab a running belt or armband for your keys and phone. And yes, music or a podcast makes things easier — just don’t blast it so loud you can’t hear traffic or rogue cyclists.
And here’s a tip: community helps. Whether it’s a local running group or an online forum, chatting to others who are just as bewildered by gels, gait analysis, and Garmin stats can keep you going. Plus, it’s always nice to know you’re not the only one googling “why does my ankle click after every run?”
Training for a Half Marathon (Yes, I Know, It Sounds Mad)
If you’d told me at the beginning that I’d be training for a half marathon, I would’ve laughed (and probably reached for another biscuit). But here we are.
You don’t start with a half marathon. You build up. Slowly. Most beginner plans are around 12–16 weeks long, with a mix of short runs, longer ones, and those sweet, sweet rest days. Aim for 3–4 runs a week, and adjust if your body tells you it’s had enough.
Cross-training is brilliant for keeping things balanced. Cycling, swimming, or even a bit of strength training can help protect your joints and build stamina. It’s not about becoming a gym bro — it’s about giving your running muscles a bit of backup.
And don’t skip stretching. I used to think yoga was for people who collect crystals, but it’s saved me more than once from hobbling down the stairs like I’m 90.
Recovery isn’t sexy, but it’s crucial. Eat well, drink water, sleep properly, and for the love of your calves, listen to your body. If something hurts, ease off. You’re not on a deadline.
Mental prep matters too. Visualise crossing that finish line. Remind yourself that you can do hard things. And if all else fails, find a mantra. Mine is usually something like “don’t die, don’t puke, keep going”.
As race day creeps closer, you’ll likely feel everything from excitement to existential dread. That’s normal. Trust your training, get some carbs in you, and try not to buy five new bits of kit in a panic.
Because if there’s one thing I’ve learned, it’s this: running after 40 isn’t about being fast or flashy. It’s about reclaiming a bit of yourself. One sweaty, glorious step at a time.
