Plagued by runner's knee? Here's how to avoid and treat it

Knees are delicate things. While some runners might experience a twinge every now and then, knee pain can be the reason some runners have to stop altogether. Because of this, it’s important to tune into your body and catch any issues early on.

Knee pain from running occurs for a number of different reasons. Unfortunately, there isn’t one solution. However, this guide will help you understand your knee pain and hopefully keep it under control.

What is runner’s knee?

Patellofemoral pain syndrome, otherwise known as runner’s knee, is a fairly generic term for knee pain from running. It tends to involve a dull pain around the front of the knee, and you might notice a popping or clicking sound when you move your leg in a certain way. 

Runner’s knee tends to occur when you run too far too fast and your knees aren’t prepared. It can also be down to the way you’re running or a lack of muscle strength.

While runner’s knee is common, it’s important to note that there are a number of different causes of knee pain. It could be something else such as bursitis or arthritis, and your GP will be able to diagnose the issue.

Prevention

Lots of people think that running is as simple as putting one foot in front of the other. But it’s much more complicated than that. One of the things runners have to think about is preventing injuries - especially if you’re training for a race. You don’t want to have to duck out at the last minute due to knee pain, so here are some tips for prevention.

Training sensibly 

Since runner’s knee often boils down to overuse, it’s important to follow a training plan if you’re planning on running a significant race. If you start running intense distances with little or no preparation, your body will suffer and you could have a serious injury. Training plans ensure that you prepare for a race safely and sensibly, with plenty of rest days in between. 

The right shoes

Most runners agree that the right shoe helps their knees. Shoes handle the shock that is created by the impact of your foot striking the ground. However, there’s some debate in this area. A 2018 study showed that trainers that are too cushioned could actually contribute to running related injuries - including knee pain. Some even vouch for barefoot running, where you don’t wear shoes at all. So, what’s the answer? It seems that, while you don’t want super bouncy trainers, you still need the right ones for you. The perfect trainer will support your ankles and feet, and keep everything well balanced.

Adjusting your technique

Knee pain can also be caused from a lack of technique. There are certain ways of running that can cause knee pain, such as over-striding, lifting the knees too high and leaning backwards. When running, try to lean forwards and focus on keeping your knees soft and bent. A gait analysis will help in assessing how you run and finding any problem areas. It’ll also help you find the right pair of shoes.

Strength training

Runner’s knee can also be a result of weak muscles - especially in the thighs and hips. Hip weakness can force your thigh to move irregularly when running and pull inwards, which puts excessive strain on the knees, while thigh muscles - especially the quadriceps - are directly related to the way you straighten and bend your knees. So, it’s important to do strength training alongside your running and build these muscles.

Stretching

All runners know the importance of stretching. But even I’ll admit that when I’ve been pushed for time in the morning I haven’t stretched for as long as I should. Stretching properly before running can reduce the likelihood of knee pain as it strengthens and exercises the muscles surrounding the knees, giving them more support. You should stretch for at least 10-15 minutes before running and use a range of exercises or, alternatively, try out our Pre-run yoga routine.

Treatment

Unfortunately, knee pain from running can still occur even when you’ve done everything right. In this case, it’s important to know how to treat the pain so you can recover as quickly as possible.

Rest

Once you’ve experienced knee pain, it’s important not to put pressure on the area. Keep your leg elevated and avoid putting weight on it. Stop running until you’ve spoken to your GP and established the next steps.

Ice

Ice is always the go-to method for reducing inflammation. Keep the leg elevated and use an ice pack or bag of peas on the knee for 15-20 minutes three or four times a day.  

Knee brace

After resting your knee for as long as the GP recommends (which could be for weeks - or months), it might be time to start running again. If you’re ready, use a knee brace to shift the weight off the damaged part of your knee. You’ll need to start slowly and combine your run with plenty of walking, too.

The Challenges Women Face in Running and How It Impacts Participation

Running is often lauded as one of the most accessible sports—just lace up your trainers and go. However, for many women, the barriers to participation go far beyond the logistical. While safety concerns are frequently highlighted, deeper systemic issues like access to the sport and unequal treatment are also preventing more women from running. It was a topic keenly discussed at our In Her Stride panel held at the end of November, with key members of the female running community including Sophie Power, Tasha Thompson, Rehana Mawani and Emily Shane. 

Running is often lauded as one of the most accessible sports—just lace up your trainers and go. However, for many women, the barriers to participation go far beyond the logistical. While safety concerns are frequently highlighted, deeper systemic issues like access to the sport and unequal treatment are also preventing more women from running. It was a topic keenly discussed at our In Her Stride panel held at the end of November, with key members of the female running community including Sophie Power, Tasha Thompson, Rehana Mawani and Emily Shane. 

Before we kick things off however, we should highlight that female participation in running events is growing, and this is a great thing! According to data from Let’s Do This, women in their 20s are the fastest-growing demographic in event participation this year. However despite this, women are still 16% less likely to run every week compared to men. This disparity is particularly striking given that women report higher levels of personal benefits from running, such as improved fitness, better sleep, and reduced stress.

The reasons for this are complex and personal, however we have broken down three key challenges discussed during our panel and the solutions explored that could help address them.

1. The Pressure of Pace

One of the biggest hurdles for many women is the pressure to run faster. Despite the average UK woman’s running speed of 06:37 min/km (according to Strava), most run clubs don’t cater to this with the slowest pace often around 6 minutes per km. Add to this the relentless focus on personal bests and fast times on social media, and it’s no surprise that many women feel too intimidated to join in. 

Thankfully, there are starting to be more people rebelling against this speed obsession, including our panelist, Emily Shane. Emily has been leading the charge to encourage more women to disregard pace and focus on the experience of running to drive uptake amongst women. Initiatives like events without cutoff times and more inclusive pace groups at running clubs are vital to creating a more welcoming environment and broadening the benefits of running to the experience and community. 

2. Perception of Sport in Schools

One of the topics hotly discussed was how for many girls, the barriers to enjoying physical activity start at school. Puberty, coupled with changing bodies and fluctuating emotions, can make sports feel daunting and uncomfortable for teenage girls. Research highlights this disparity: only 38% of girls enjoy sport and exercise compared to 53% of boys, and just 26% of girls feel confident in physical activity versus 43% of boys.

The panel emphasised the need to address this such as:

  • Introducing a wider variety of sports and fitness activities to cater to different interests
  • Providing more supportive and confidence-boosting PE kits.
  • Showcasing more female role models in sport to inspire young girls.

By addressing these issues at the school level, we can foster a love of sport that lasts into adulthood.

3. Treatment at Events

This is a topic that panelist Sophie Power, founder of SheRACES is incredibly knowledgeable and passionate about. Even at organised running events, women often experience unequal treatment. From “unisex: t-shirts (which are actually designed for men) to a lack of sanitary products in portaloos, these "small things" can collectively make women feel like an afterthought. Prize money inequality and rigid event policies—like no deferral options for pregnant or postpartum women—further highlight these disparities.

Thankfully, initiatives like the 50:50 campaign by Threshold (a campaign to get 50% of women at Ultra startlines vs. the current average of 30%) and the advocacy work of SheRACES are driving change, and there are many amazing event organisers such as Maverick, Threshold, Why We Run and many more, that are working hard to make their events are inclusive as possible for women. 

Despite these challenges, the panel and attendees felt overwhelmingly optimistic about the future of running for women and the benefits it brings us. Progress is being made, however we all need to add our voices to the conversation to help more women get into the sport and reap the benefits. 

Some Helpful Resources

Here are a few helpful resources. This list isn’t exhaustive by any means, however is a good starting point for those looking for inspiration on where to start.

From Radio to Race Day: Hattie Pearson’s Path to Endurance Event Glory

Hattie Pearson is the type of person who doesn’t just dabble in fitness (or most things…!) She dives in headfirst, often with no hand-holding (except, perhaps, metaphorically). From her first triathlon in 2021 to a series of jaw-dropping endurance feats in 2024, she’s been redefining what’s possible with determination, community, and a big ‘YES’ attitude.

Hattie Pearson is the type of person who doesn’t just dabble in fitness (or most things…!) She dives in headfirst, often with no hand-holding (except, perhaps, metaphorically). From her first triathlon in 2021 to a series of jaw-dropping endurance feats in 2024, she’s been redefining what’s possible with determination, community, and a big ‘YES’ attitude.

Just say YES

Hattie’s ‘yes’ streak started when a friend and her decided to do a sprint triathlon together. “We had such a great time,” Hattie recalls, “and I was like, I want to do more of this.” That spark quickly turned into a blaze of ambition. By the following year, she was competing in Outlaw triathlons and even signing up for a full-distance Ironman—before completing her first half-distance event. “I didn’t give myself the choice to not carry on,” she says.

The Power of Community

For Hattie, discovering the 10IronWomen network—a group committed to gender parity in triathlons—was a game-changer. “It’s amazing to see a community encouraging women and non-binary folk to show up,” she explains. “Seeing others doing it made me think, I want to be a part of this.” That sense of solidarity and shared purpose has been a recurring theme, whether she’s lacing up for a winter triathlon in the Alps or a grueling ultra-marathon closer to home.

A Year of Big Goals

This year, Hattie set herself a dizzying list of challenges. She swam 500 kilometers (yep, that’s half a million meters!) and tackled a range of events, including a winter triathlon complete with ski touring, the Étape du Tour cycling challenge, and her first ultra-marathon. Each was hard in its own way—whether it was battling snowy trails with crampons or smashing out seven-and-a-half-minute miles for 13.1 miles. But for Hattie, the difficulty is the point. “Every time I achieve something I thought was impossible, I remind myself: I can do hard things.

Balance and Burnout

With goals that ambitious, fitting it all in can be a challenge. Early mornings help. “I’m one of those people who can get up at 5:00 a.m,” Hattie admits, however it also takes a lot of discipline. With her work on Hits Radio starting later in the day, she carves out time for training, dog walks, and the occasional tantrum over broken goggles. “I’ve definitely had those ‘forgetting-my-swimming-costume’ moments,” she laughs. But her key to staying motivated is simple: keep it fresh and fun. Whether it’s joining her triathlon club for training or trying a completely new event, keeping it fun and different is the secret to staying motivated and on track to reach your goals. 

Advice for Aspiring Endurance Athletes

For anyone looking to follow in her footsteps (or strokes), Hattie has this advice:

  • Be patient. Results don’t come overnight, and the journey is as important as the destination.
  • Stop comparing. “Your journey is completely your own. Social media only shows the highlights,” she reminds us.
  • Find your community. Whether it’s a running club, a neighbor for early morning jogs, or an online network, accountability and camaraderie make all the difference.

What’s Next for Hattie?

In 2025, Hattie plans to tackle her first multi-day event, the Monster Triathlon. Admittedly it is as scary as it sounds, kicking off with a 5K swim in Loch Ness, followed by a 1,000-kilometer bike ride to Windsor, and wraps up with a casual 50K run to London(!). Her goals also include more open-water swimming, trail running, and maybe—just maybe—an even bigger endurance challenge. (Though definitely not swimming the English Channel: “No way am I swimming through jellyfish without a wetsuit!”)

Hattie Pearson’s journey is more than a personal triumph. It’s a testament to the power of showing up, saying yes, and proving that with the right mindset, anything is possible. Whether you’re tackling your first 5K or dreaming of an ultra-marathon, Hattie’s story is proof that the finish line is worth the hard miles. And when you cross it? You’ve won your race—medal or not. 🏅
