What happens when a former professional triathlete and endurance coach suddenly develops a painful plantar plate sprain? In this episode of the Doc On The Run Podcast, Dr. Christopher Segler speaks with Marcus, a former professional triathlete and current triathlon coach from Brazil, during a real running injury strategy call focused on plantar plate injuries in runners and triathletes. Marcus had to cancel an upcoming 45K trail race after developing sudden pain under the ball of the foot consistent with a plantar plate sprain. During the call, they discuss how plantar plate injuries develop, why bunions and shoe selection can increase stress on the plantar plate ligament, and how endurance athletes can protect the injured ligament while maintaining fitness. They also discuss: • Why MRIs often fail to tell the whole story with plantar plate tears • Whether carbon-plated running shoes can reduce plantar plate strain • How to maintain fitness without worsening the injury • Why boots alone are often not enough • The biggest mistakes runners make during plantar plate recovery • How shoe construction can affect forefoot stress • Why triathletes are uniquely vulnerable to forefoot overload injuries If you’re a runner or triathlete struggling with forefoot pain, second toe pain, a plantar plate tear, or a plantar plate sprain, this episode will help you better understand the injury and what actually matters during recovery.

If you have popping or clicking around the outside of your ankle, do you actually need peroneal tendon surgery? Not necessarily. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains the 5 reasons runners might actually consider surgery for painful popping peroneal tendons—and why many runners may not need surgery at all. In this episode, you’ll learn: • What the peroneal tendons actually do • Why peroneal tendons pop or click • When popping is actually dangerous • The difference between painful instability and harmless clicking • Why some split peroneal tendons heal without surgery • The most important question runners forget to ask surgeons • How to think about surgery from a runner’s perspective The real goal is not simply fixing the tendon. The goal is getting back to running.

How do you know if your stress reaction just turned into a stress fracture? That’s one of the most important questions a runner can ask—because once there’s a crack in the bone, everything changes. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains the 5 key signs that indicate your stress reaction may have progressed into a true stress fracture. Understanding these signs can help you avoid making the injury worse and make smarter decisions about training and recovery. In this episode, you’ll learn: • The difference between a stress reaction and a stress fracture • Why that distinction matters for runners • The 5 warning signs your injury has progressed • The most reliable sign that you may have a crack in the bone • Why bruising is a major red flag • How to think about injury severity when making training decisions If you want a clearer way to assess your injury, get the free Stress Fracture or Injury Self-Assessment Worksheet at: https://www.stressfracturesecrets.com/mistake

If you have plantar fasciitis and you’re trying to keep running, you’ve probably been told to stretch, rest, or stop running altogether. But what if the solution is much simpler? In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains the one simple trick he personally used to fix his plantar fasciitis while training for Ironman races—without stopping running. This episode breaks down how small biomechanical changes can dramatically reduce stress on the plantar fascia and allow healing while maintaining fitness. In this episode, you’ll learn: • What the plantar fascia actually does • Why plantar fasciitis develops in runners • How road slope changes stress on your foot • The simple adjustment that reduced strain instantly • Why small changes can make a big difference in healing • When this trick will work—and when it won’t

If you have a calcaneal stress fracture and a 100-mile race on your calendar, the question is simple… Can you still run it? In this episode of the Doc On The Run Podcast, Dr. Christopher Segler lets you listen in on a real strategy call with an ultrarunner trying to decide whether he can complete a 100-mile race in just over two months after being diagnosed with a calcaneal stress fracture. This episode breaks down the real risks, the real decisions, and the exact strategy needed to balance healing with maintaining fitness. In this episode, you’ll learn: • Why calcaneal stress fractures are especially risky for runners • The biggest danger that could permanently end your running • The 3 key signs that tell you if you're getting better or worse • How to maintain fitness without making the fracture worse • The most dangerous time before your race (when most runners make mistakes) • How to find the exact line between healing and training If you want a clearer way to assess your injury, get the free Stress Fracture or Injury Self-Assessment Worksheet at: https://www.stressfracturesecrets.com/mistake

What do you do if you’ve been training for months and suddenly get a stress fracture right before your race? In this episode, I explain the four real options runners have when they don’t want to cancel—and how to think about risk, recovery, and still crossing the finish line.

If you have been out of running for weeks with a fibular stress fracture and the pain is gone, but you still feel a little pressure at the injury site, should you wait until you are 100% symptom-free before trying to jog again? That is the question in this episode of the Doc On The Run Podcast. In this episode, Dr. Christopher Segler explains why the answer is not based on time alone. Just because you have stopped running for four to six weeks does not automatically mean the bone is ready for impact. What matters more is whether your symptoms are improving, whether you can tolerate increasing load without worsening symptoms, and whether you have rebuilt enough strength and stability to run safely. In this episode, you will learn: Why “no pain” does not always mean “fully healed” Why a slight sensation does not automatically mean you are not ready The 3 key factors to assess before a return-to-run test Why the fibula is lower risk than the tibia, but still needs a careful approach The biggest mistakes runners make when returning after a stress fracture How to know if your recovery progression is actually working If you want a clearer way to assess your injury, get the free Stress Fracture or Injury Self-Assessment Worksheet at: https://www.stressfracturesecrets.com/mistake

If your doctor told you that you have a plantar plate injury, did they mean stress, strain, or sprain? Those terms sound similar, but they mean very different things when you are trying to heal and still run. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains the biomechanical difference between plantar plate stress, plantar plate strain, and plantar plate sprain, and why understanding those terms can help you avoid delayed healing, unnecessary time off, and long-term toe instability. In this episode, you’ll learn: What the plantar plate actually does The difference between stress, strain, and sprain Why runners often get plantar plate injuries at the second toe How to tell whether your plantar plate is irritated or actually injured The two biggest mistakes runners make when trying to return to training How to modify workouts without making the injury worse If you want a clearer way to assess the severity of your injury, get the free Stress Fracture or Injury Self-Assessment Worksheet at StressFractureSecrets.com. This description reflects the transcript’s focus on distinguishing load versus actual ligament damage, the signs of instability, and the practical return-to-running decisions runners need to make.

If you have peroneal tendon pain and one doctor says your MRI shows a tear while another says it is just post-surgical change, what are you supposed to do? That kind of conflicting advice can leave runners completely stuck. You do not want unnecessary surgery, but you also do not want to keep training on a tendon that may actually be torn. In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains a practical framework runners can use when MRI findings and medical opinions do not match. In this episode, you will learn: • Why peroneal tendon injuries are often difficult to diagnose accurately • How MRI can sometimes overcall or miss a split tear in the peroneal tendons • Why different doctors may look at the same scan and reach different conclusions • Four practical options a runner can consider before making a major decision • Why diagnostic ultrasound can sometimes add more useful information than another opinion alone • How to think about a careful test run without masking pain signals with ibuprofen If you are trying to decide whether your peroneal tendon is healing, needs more imaging, or might need surgery, this episode will help you think more clearly about your next step.

When is it actually safe to start loading a stress fracture again? In this episode, Dr. Christopher Segler explains how runners can think about progressive bone loading without making the injury worse. He covers why “just rest” is incomplete advice, why pain relief does not equal full healing, the 3 phases of stress fracture recovery, and the biggest mistake runners make when they try to return too soon.
