What would you do if you got a tibial stress reaction or a tibial stress fracture while training for a 153 mile race? Ultrarunner Whitney had a major goal: finish Spartathlon, the 153-mile race from Athens to Sparta. But five months before race day, an MRI showed a tibial bone stress injury. In this interview, Whitney shares her running background, the emotional impact of the diagnosis, how she worked with her doctor and coach, and the meticulous symptom tracking and modified training that helped her prepare. She also recounts the race itself, the mental challenges of ultrarunning, and her advice to runners facing a difficult decision about a goal race. Her story is not a universal medical protocol: significant tibial bone stress injuries require individualized assessment.

Peroneal tendinitis can become a huge problem when you are a runner with a race on the calendar.   In this episode, Dr. Christopher Segler explains three things runners should question when trying to calm down irritated peroneal tendons without unnecessarily losing running fitness.   We discuss why corticosteroid injections around a tendon can create concerns, why randomly switching among different running shoes may not help an already irritated tendon, and why automatically spending 4 to 6 weeks in a fracture walking boot can create a new set of problems for a runner.   The goal is not simply to make the tendon quiet. The goal is to understand the injury, protect it appropriately, maintain as much fitness as possible, and build a strategy that matches your race goals.

If you are a runner with a plantar plate sprain and you already had an MRI, but you are still not getting better, the MRI report may not answer every question that matters.   In this episode, Dr. Christopher Segler explains four questions he believes runners should ask their doctors about MRI imaging of a plantar plate injury. He discusses MRI slice thickness, why the plantar plate is difficult to image, why your doctor should personally review the MRI images instead of relying only on the radiology report, why you should ask to see the suspected plantar plate injury on the images, and when ultrasound may help confirm what is actually happening.   The goal is to help runners have a more useful discussion with their doctors, better understand the severity of the injury, and avoid losing unnecessary running fitness while waiting for a workable plan.

A runner recovering from an overtraining injury may notice new sensations, tension, discomfort, or other “noise” as activity increases. That can be confusing, especially when the goal is to rebuild strength without overloading tissue that is still weaker than normal. In this episode, Dr. Christopher Segler explains a simple construction-site analogy for understanding some of the sensations that can show up during recovery. Healing tissue requires materials to be carried in and damaged materials to be carried out, and fluid movement around the injury can create sensations that become more noticeable as activity increases. The key is not to ignore pain or major swelling. It is to understand what the changes mean by carefully tracking injury severity, daily steps, repetitions, symptoms, and how those measurements change as activity increases. The goal is to match the strength of the healing tissue with the right strength-building activity so you can keep progressing without overloading the injured structure.

What should you do if you are five weeks away from a half marathon and develop a metatarsal stress reaction? In this episode, Dr. Christopher Segler talks with a real runner who is preparing for a half marathon in Argentina after developing a fifth metatarsal stress reaction. He has already stopped running for five weeks and has been maintaining fitness with stationary cycling. The discussion focuses on the information a runner needs in order to decide what activity can be added safely: establishing injury severity, tracking pain trends, monitoring tenderness, reducing inflammation, maintaining strength and stability, and increasing stress on the bone systematically instead of simply going out for a test run. Dr. Segler also explains why X-rays can miss some stress fractures, how MRI and ultrasound may provide additional information, why zero pain is not always the only useful benchmark, and why runners need measurable baseline numbers before progressing activity.

How much should you move your ankle when you have a metatarsal stress fracture? An elite Masters track athlete asked Dr. Christopher Segler this question after noticing that her ankle was getting stiff while wearing a fracture walking boot for a third metatarsal fracture. Ankle stiffness matters because once you return to running, restricted motion can increase the forces applied to the foot and may contribute to other overtraining injuries. But aggressively forcing ankle motion while the metatarsal is still healing can also put unnecessary stress on the injured bone. In this episode, Dr. Segler explains the concept of doing “a little motion, a lot” instead of “a lot of motion, a little,” why frequent gentle ankle movement may be preferable to forceful end-range stretching, and why tracking discomfort is essential when deciding when to increase activity.

What should you do when Achilles tendon pain comes back after you thought it was better? In this episode, we listen in on a real strategy call with a runner who had Achilles tendinosis for years, improved after treatment, returned to running, and then had the pain flare again after hill training. The key lesson is that the next step is not guessing which treatment might work. The next step is figuring out exactly how severe the problem is, what activities trigger it, and what information you need to make a smart decision about running, treatment, and recovery. If you have Achilles pain that keeps coming back, this episode will help you think more clearly about what to track, what to avoid, and how to build a better plan.

A runner with a third metatarsal stress fracture was doing everything right. Her injured left foot was getting much better — but then her “good” right foot started aching. That can be frightening. Does it mean you are developing another stress fracture? In this episode, Dr. Christopher Segler explains why the uninjured foot can become overloaded when you are using a fracture walking boot, crutches, or a knee walker, how compensatory stress can trigger metatarsal aching, and why you should not simply ignore new pain in the other foot. You’ll also learn why systematically tracking pain and activity can help you determine whether the aching foot is getting better or heading toward a more significant problem.

A runner thought he had another ordinary ankle sprain. He could still walk, he checked the Ottawa Ankle Rules on himself, and he concluded that he did not need an X-ray. But almost a week later, the swelling and bruising still were not behaving like his previous ankle sprains - and the X-rays showed that his ankle was actually broken. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why runners can be especially vulnerable to self-diagnosis after an ankle injury, how an athlete's pain tolerance can make a serious injury seem deceptively manageable, and why a clinical decision rule is not the same thing as examining yourself. In this episode you'll learn: • Why runners may underestimate the significance of pain after an ankle injury • What the Ottawa Ankle Rules are actually designed to do • Why being able to walk does not prove that your ankle is not broken • How extensive bruising and persistent swelling change the level of concern • Why a violent inversion-and-eversion mechanism deserves extra attention • How anchoring bias can make a familiar ankle sprain diagnosis feel more certain than it really is • When an ankle injury is not following the expected recovery trajectory • Why objective evaluation matters when an injury simply is not behaving normally

Can a stress fracture actually heal with too much bone? Yes - and in some runners, that extra bone canbecome a problem of its own. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why a very large bone callus does not always mean a stress fracture is safely healed. He walks through two runner cases: one in which a large callus hid an unstable fracture heading toward nonunion, and another in which prolonged irritation produced a completely healed but excessively thick metatarsal that crowded the surrounding soft tissues. In this episode you'll learn: • Why bone callus forms around a stress fracture • How continued motion can create a deceptively large callus • Why a big callus can coexist with an unstable fracture or nonunion • How prolonged irritation can leave a healed bone too thick • Why excess bone can crowd muscles, nerves, and other soft tissues • Why simply “running less” may not reduce stress enough • What pain, bruising, and swelling can tell you about injury severity • Why measuring improvement matters before you increase activity

Can you still do your race after breaking a toe? Many runners assume a broken toe automatically means canceling the event. But that's not always true. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler shares a real strategy call with a runner preparing to hike the Tour du Mont Blanc after suffering a displaced fourth toe fracture only one week before departure. In this episode you'll learn: • The two complications that can permanently affect future running after a broken toe • Why pain isn't the only thing you should monitor • How swelling predicts future problems • Why shoe stiffness matters more than most runners realize • How to determine whether your toe is stable enough to test • Why a broken toe doesn't always mean canceling your race

Have you ever felt guilty about taking a day off during stress fracture recovery? For many runners, the hardest part of getting back to running isn't the injury itself—it's resisting the urge to complete every planned workout. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler shares a simple mental strategy that can help runners recover faster by changing the way they think about recovery days. In this episode, you'll learn: • Why runners often feel guilty about taking a recovery day • The biggest mental mistake competitive runners make during stress fracture recovery • How soreness and fatigue can actually become valuable warning signs • Why your coach wants you close to the injury threshold—but never across it • The simple mindset shift that can prevent setbacks • Why "earning" a day off can help you recover faster and race sooner • How to balance fitness gains with protecting a healing stress fracture The goal isn't simply working harder. The goal is getting stronger while protecting your healing bone so you can get back to racing as quickly as possible.

Have you ever felt a strange sensation that seemed like a rubber band squeezing your Achilles tendon, shin, or foot? It may not be pain… But it might be one of the earliest warning signs that you're about to make a running injury worse. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler introduces what he calls the "Rubber Band Sign"—a subtle sensation reported by runners with Achilles tendon injuries, tibial stress fractures, and metatarsal stress fractures that may signal increasing stress before significant pain develops. In this episode, you'll learn: • What the "Rubber Band Sign" feels like • Why runners describe it before pain develops • How it may relate to Achilles tendinosis and stress fractures • Why swelling around injured tissue may create this sensation • What to do if you notice it during your return to running • Why paying attention early may help you avoid a bigger setback The goal isn't simply recognizing another symptom. The goal is recognizing an early warning sign before your injury gets worse.

When your doctor recommends surgery, there is one question most runners never ask. But it may be the most important question of the entire conversation. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why runners should not simply accept a recommendation for surgery without understanding how confident the surgeon is that the procedure will actually get them back to running. Using a recent second-opinion strategy call with an experienced ultrarunner, Dr. Segler discusses how asking for a "guarantee" isn't really about demanding certainty—it's about understanding your surgeon's confidence, expectations, and reasoning. In this episode, you'll learn: • The one question most runners are afraid to ask before surgery • Why "Can you guarantee I'll get back to running?" is really about confidence, not contracts • How surgeons think differently about different injuries • Why vague surgical recommendations should prompt more questions • How to decide whether surgery truly supports your running goals • Why reassurance and clarity matter before making a permanent decision The goal is not simply having surgery. The goal is choosing the treatment that gives you the best chance of getting back to running.

When is the single most important time during the healing of a metatarsal fracture? Most runners assume the hardest part is waiting weeks to get back to running. In reality, the most critical period may be the very first week after the fracture occurs. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains why the first seven days after a metatarsal fracture lay the biological foundation for healing, and why seemingly small mistakes during that first week can delay your recovery. In this episode, you'll learn: • Why the first week is biologically the most important phase of healing • What happens during the inflammatory phase after a fracture • Why bone stability is essential for successful healing • How movement disrupts the body's repair process • Why even sleeping without your boot may slow healing during the first week • How small movements from exercise can delay recovery • What runners should focus on before worrying about fitness The goal is not simply surviving the first week. The goal is creating the strongest possible foundation for the bone to heal so you can get back to running sooner.
