Run Strong, Hurt Less: How to Suffer Smart (Without Your Feet Filing a Complaint)

Every runner knows what it feels like to push through pain. But how do you know when you're building yourself up — or quietly breaking yourself down?

In this episode of The Runner's Sole Podcast, podiatrist Sharon Miller breaks down the science of smart suffering — so you can train harder, recover faster, and stay on the road longer without landing on the injury list.

From the difference between productive pain and warning signs, to why your tendons lag behind your fitness, to the honest truth about shoes and strength training — this episode gives you everything you need to stop guessing and start training with real, foot-first intelligence.

🎧 IN THIS EPISODE YOU'LL LEARN:
✔ Good pain vs. bad pain — and how to tell the difference while running
✔ Why your feet absorb 2–3x your body weight with every single step
✔ The real reason most running injuries happen (it's not bad luck)
✔ How overstriding and low cadence increase your injury risk
✔ Why buying new shoes won't fix a training error
✔ The strength exercises every runner needs (yes, including your toes)
✔ Exact warning signs that mean you need to stop — not push through
✔ Why recovery, not running, is where improvement actually happens

👣 KEY TAKEAWAY
Suffering is part of running. But there's a big difference between building fitness and building an injury.
The runners who go the distance aren't just training hard — they're training smart, staying consistent, and listening to the one part of their body that never lies: their feet.

Welcome back to the Runner Soul. This is the place where running meets science stride by stride. And as ever, I am Sharon, your resident podiatrist, and I'm also a runner, and you guessed it, a foot nerd. Welcome back. Today we're talking about something every runner secretly prides themselves on. Yes, you guessed it. Suffering. Yes, we love to suffer. That noble art of questioning your life choices halfway through a run. But here's the twist. Today we're going to learn how to suffer intelligently. We are going to learn to suffer for your higher good. So your feet don't revolt and force you into an unwanted relationship with the sofa. We don't want you on the sofa. And we're doing it from a podiatry perspective. Because your feet, whether you like it or not, they are in charge. And so let's clear something up straight away. That is not all pain is created equal. Because there's always a good fairy and there's always a bad fairy. And in this case, there is good suffering and there's bad suffering. So, what entails the good suffering? Well, the good suffering, if your legs are burning a little bit, you're breathing like a broken accordion, and you're wondering why you didn't use swimming or gymnastics, and that's the good suffering. Now the bad suffering, that's when you feel a sharp pain, it's starting to limp, it's starting to change your gait, you're starting to walk differently, and that very specific spot on your foot is screaming, we need to talk. So from a podiatry point of view, your feet are like that brutally honest friend. Yes, they will tell you that your bomb does look big in those trousers. They won't sugarcoat anything. So if something's wrong, your feet will let you know repeatedly. And don't try to ignore them, because that's how you go from a slight niggle to why am I googling crutches at 2 a.m. We all need a quick reality check because every time your foot hits the ground, it's dealing with three to five times your body weight. So if say you weigh 70 kilograms, well that could be over 300 kilograms per step. Now multiply that by thousands of steps, and you can see where your feet are coming from. Your feet aren't just working hard, they're basically running a full-time job with zero annual leave. And they have lots of work to do. They have lots of lots of tasks like absorb shock. They are responsible for adapting to every different terrain you're walking in. They are responsible for propelling you forwards, they're responsible for keeping your balance. And what do we do? Yeah, we reward them by stuffing them into the tightest possible shoes and running more and more and more and more. Why do runners get injured? Well, here's the spoiler alert. It's not actually bad look. Most injuries don't come from one dramatic moment. No no no. It's usually a case of I felt great, so I doubled my mileage, I added some heels, and I put on my new shoes all in the same week. It's classic. So here's the science, and don't worry, it's the painless version. Your fitness improves quickly. Your tendons and your bones do not. They have a little bit of catching up to do. So your brain might say, Let's go, we can do it, but your feet are saying, hmm, we're not emotionally or structurally ready for this yet. So the result is overload. So think of your body like it's like a Wi-Fi connection. So the muscles are the full signal, your tendons are like the buffering, and the bones, well, they're still connecting. And on to the biomechanics, which is very important. And I hear you all say, what does biomechanics mean? Well, that means how you run. And how you run does really matter. So let's talk about how you run. Now, small little things make a big difference, as in everything in life. So if you're over striding, then that's more impact, that's more stress. Low cadence, that means a bigger load per step. If you've got poor control and you're wibbly wobbly, then your foot compensates for everything. Your foot, it's basically the customer service department of your whole body, and it deals with all the complaints, all the coming down from above, all the shit basically.

Shh. Did I say that?

Now, also, if you have bad hip control, the foot has to deal with that. It's gotta compensate. If you've got tight ankles, the foot has to deal with that. Yeah, more work, gotta compensate. And life stress? Okay, maybe not that one, but yeah, to an extent, yeah. It it still does have to compensate in some way. The shoes are helpful, but they are not a magic wand. They are not a magic carpet, unfortunately. So let's address the elephant in the running store. Now, shoes are great, but they are not miracle workers. Buying new shoes while ignoring training errors is like putting on a fancy new tire on a car and then driving into a wall. What's the point? What actually matters is the comfort, the fit, and the gradual adaptation, and also rotating your shoes is a great idea. It slightly changes how your foot is loaded and how it has to work, and it means it reduces some repetitive stress. Plus, let's be honest, it justifies buying more shoes, and it's nice to treat yourself because you're worth it. And now we move on to strength training. Yes, I'm afraid you do have to do it. I know you just want to get out there and run, but it's a bit like painting a room without your preparation. Sure, you can slap the paint on the walls, but it's not gonna stay there and it's not gonna look good for very long. So, if you want to suffer more safely, you need stronger feet and legs and muscles. So the key exercises are calf raises. Your ankyles will definitely thank you. Eventually, you need some balance work, which is important for the whole of your life, because you know, to be mobile for the rest of your life and not end up in a wheelchair or with walking aids when you get older, it's all about your balance and it's about the strength. So, foot strengthening is a yes, yes, yes, yes, yes, yes, yes, yes, yes. Your toes have jobs to do as well, they're not just there to be painted or to be going, Eh. I know a lot of men come to me and they say, Oh, my wife hates my feet. She looks at them and she goes, Uh you've got ugly feet. Well, you don't have to have ugly feet if you look after them. We will give you tips to have beautiful feet and not just beautiful feet. We want beautiful, functioning strong feet. So the stronger the tissues, the more low tolerance, and the fewer dramatic injury breakdowns. And the warning signs. Now, please don't be that runner because every runner has ignored pain at some point. Especially if you're male, you want to be macho, you think I'm not gonna let this pain keep me back. But here's when to pay attention. So pain that changes how you run, pain that gets worse the next morning, and pain that's in one very specific sore spot. Now the last one is especially suspicious because general soreness is fine. It's like you know, when you climb up a hill and you come back and your legs are all wibbly wobbly because you know that you've worked hard. You know, that's fine, but not if you are in constant pain. You you know the difference, and one exact point of doom is not fine. So these are the things to look out for. And here's your boring seeker weapon. What is it? Recovery! Here's the part no one brags about on social media. Recovery. Don't approve during your run, you improved while. Sleeping, eating, not running. Shocking, I know. Because recovery is all about that rest. We need to have that rest. So skipping recovery is a bit like making a cake and taking it out halfway through. It looks okay, but something's very wrong. And it doesn't taste very good. And my final thought about suffering smart. Look, running is supposed to be hard sometimes. If it was easy, everybody would be doing it. And if it was so easy, there wouldn't be any point. That's why we gain such benefits from running. Not just physically, but also mentally as well. And that is all part of why we love it. But the goal isn't to destroy yourself, it's to build yourself. And the best runners don't just train hard, they train consistently, they know it's very important to rest and have days off, and it's this consistency that happens when you stay injury free. So, in closing, next time you're out running and things start to niggle and you start to feel, hmm, is my body trying to tell me something? So ask yourself the question: is this productive suffering? Am I going to benefit from it? Or is this the start of a very bad decision? Well, your feet already know the answer to that one, and deep down you do too.
