They'll call it a lateral ankle sprain. They'll ice it, tape it, and be back four weeks later with the same problem — because a peroneal tendon injury doesn't follow the same rules.

The outer ankle is a crime scene with multiple possible perpetrators. In this episode, we work through all five: the sprain that brought the tendons down with it, the overuse pattern built on cambered roads, the shallow groove that lets the tendon escape with every step, the longitudinal split tear that standard MRI misses, and the high-arched foot that loaded the predisposition until something gave way.

We cover how to map peroneal pain away from ligament pain, the one question most clinicians never ask, why dynamic ultrasound catches what static imaging misses, and how the management pathway splits entirely depending on whether you're dealing with tendinopathy, a tear, or a tendon that's regularly leaving its groove.

This one's for every runner whose ankle sprain never quite resolved.

A deep midfoot ache. Weeks of it. A normal X-ray. A green light to keep training. And then — a complete fracture.

The navicular stress fracture is running medicine's most deceptive case. The bone sits at the apex of the medial arch, absorbs enormous compressive force at push-off, and carries a blood supply too poor to tolerate a missed diagnosis. Get it wrong and a stress reaction becomes a fracture. Get that wrong and you're in surgery.

In this episode, we work through the five suspects — athlete profile, foot geometry, training errors, RED-S, and the early warning signal that runners keep training through. We cover the N-spot, the hop test, and why a normal X-ray is not reassurance. We explain why CT and MRI are non-negotiable, why immediate removal from running is the only appropriate response to clinical suspicion, and how fracture grade determines everything that follows.

This one's for every runner who was told their X-ray was fine and went back to training anyway.

They'll call it a stiff big toe. They'll say they've always had it. They'll tell you they've just adapted. But adaptations are compensations in disguise — and compensations leave a trail.

Hallux rigidus is one of running's slowest-moving cases. The first metatarsophalangeal joint quietly loses its range. The runner quietly adjusts. And by the time pain arrives, the joint has been making compromises for years.

In this episode, we follow the evidence. We work through the five suspects driving degenerative change — from anatomical variants and old trauma to gait patterns, shoe history, and systemic arthritis. We cover how to read the gait for avoidance patterns, why weight-bearing range matters more than passive range, and how X-ray staging changes the management decision entirely.

Then we build the plan: load management through equipment, preserving the range that remains, addressing the compensating chain — and having the honest conversation about when conservative care has a ceiling and surgery becomes the right call.

This one's for the runner who's been quietly working around their big toe for years and calling it normal.

t's not always the fascia. Sometimes it's the nerve — and the nerve doesn't lie.

Tarsal tunnel syndrome is one of the most misdiagnosed conditions in injured runners. The foot burns. The arch tingles. It gets worse at rest, not on first steps. And yet it gets handed a plantar fasciitis diagnosis and a night splint, and sent on its way.

In this episode, we follow the tibial nerve into the tarsal tunnel — a narrow corridor of bone and retinaculum — and work through every suspect that could be squeezing it: space invaders, swollen tendons, pronating mechanics, post-traumatic scar tissue, and systemic nerve vulnerability.

We cover how to read the pattern, what Tinel's sign tells us, why nerve conduction studies can mislead early on, and what a proper rehabilitation plan actually looks like — from load modification to neural mobilisation to surgical decompression when all else fails.

This one's for the runners who've been told it's their fascia for six months. It might not be.
