Day 3. This is probably the worst you've felt since crossing the finish line.

Your quads are on fire. Stairs are a problem. You're walking like you've aged 30 years overnight.

This is completely normal.

Post-marathon muscle soreness peaks between 48 and 72 hours. It's called delayed onset muscle soreness (DOMS) and it's your body responding to the micro-damage caused by 26.2 miles of repetitive impact. It is not a sign that something is wrong.

Here's the part that matters: Days 4 and 5 are the trap. The soreness starts to ease. You feel human again. And the temptation to go for "just a short run" kicks in.

Don't.

Your muscles may feel ready. The deeper tissue repair isn't done. Running too early is the most common cause of post-marathon injury we see in clinic - and it's the most avoidable.

Our free 14-Day Post-Marathon Recovery Guide covers exactly what to do from today through to your first run back. Day-by-day timeline, red flags to watch for, and when it's genuinely safe to train again.

Written by Lead Physiotherapist Ian Gilham and Dr David Porter, formerly First Team Doctor at Chelsea FC.

Running ni**le or running injury? A physiotherapist explains how to tell the difference before the London Marathon.

Race week is the worst time to Google your symptoms. Every runner has aches. Not every ache is an injury.

The difference matters because the management is completely different. A ni**le needs reassurance and routine. An injury needs assessment and a plan.

Swipe through for the clinical markers we use to distinguish between the two.

If you are running the London Marathon on Sunday and something does not feel right, a physiotherapy assessment this week could be the difference between finishing comfortably and finishing with a problem that follows you for months.

Recovering from injury? This is why physio-led reformer pilates works.

Most people think of pilates as a fitness class. In a clinical setting, it’s a rehabilitation tool.

Physio-led reformer pilates combines low-impact, controlled movement with adjustable resistance tailored to each patient. That means we can target and isolate the specific muscle groups that need strengthening after injury - without overloading the body.
It’s rehab that’s built around you, not a generic programme.

If you’re recovering from a sports injury, managing chronic pain, or returning to training after surgery, reformer pilates could be the missing piece.

So many thanks to for this month’s Tatler feature on Opus.

Astrid reflects on Dr David Porter’s route from NHS A&E and intensive care into elite football, and the thinking behind Opus: bringing the standard of care typically reserved for professional sport into a clinic built around individuals, not templates.

She captures our model clearly: a highly experienced, multi-disciplinary team and a simple, rigorous framework, assess, treat, rehab, supported by thorough baseline testing and a detailed, personalised programme shaped around each patient’s overall goal.

Whether you’re recovering from injury, preparing for surgery, returning after an operation, or focusing on longevity, the approach is proactive, structured and evidence-led.

At the heart of it is the line that defines our ethos:
“No matter how good a doctor you are, you’re the support act, the patient is the star.”

To enquire or book an assessment, use the link in bio or DM “OPUS” and our team will take care of the rest.

This is Dr David Porter, Founder of Opus and Sports Medicine Doctor. 👋

David started his career in A&E and intensive care, drawn to the pace, pressure and decision-making. An opportunity to work at Chelsea FC soon followed, one he couldn’t turn down, and that began a decade working in elite football.

There were some incredible highs (including cup wins and access to cutting-edge treatments like stem cells), alongside the realities of constant travel and the politics that come with professional sport.

In 2018, David co-founded Opus with a clear aim: to make stem cell treatment accessible in the UK in a safe, ethical and research-led way, after seeing first-hand the difference it made to injured players.

Since then, Opus has evolved into a truly personalised healthcare service, looking beyond symptoms to consider biomechanics, psychology and long-term performance.

No two patients, or plans, look the same.

Outside the clinic, David’s an enthusiastic amateur weight-lifter, navigating the same work-life-training juggle many of our patients know well and occasionally struggling to practise what he preaches.
