If you feel an unusual ache in your foot during marathon or triathlon training, you might worry that you have a stress fracture. But many runners actually develop a stress reaction before a true stress fracture occurs.

The problem is that runners often ignore the early warning signs. They experiment with shorter runs, slower workouts, or simply hope the discomfort goes away.

In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains three critical first aid steps runners should take immediately when they suspect a stress reaction in the foot.

You’ll learn:

• Why stress reactions and stress fractures are closely related
• Why runners often waste valuable training time by “negotiating with themselves” about the pain
• The importance of tracking injury severity
• How comparing photos of your feet can reveal subtle swelling or bruising
• Why reducing stress on the bone is essential to prevent worsening injury

If you act quickly and manage the injury correctly, you may be able to calm the stress reaction down while maintaining your running fitness.

If you suspect a metatarsal stress fracture but your most important marathon is on the calendar, you need a plan—not panic. In this episode, Dr. Christopher Segler explains the only two questions that determine whether you can keep training (or even race) without making the stress fracture worse, plus what you should measure and track starting today.

If you think you have a stress fracture, you’re probably wondering how long it will take to heal — and when you can run again.

In this episode, Dr. Christopher Segler explains the three stages of bone healing, why early protection matters, why pain can disappear before the bone is strong, and how to safely apply stress at the right time so you don’t restart the healing clock.

If you want to heal faster and protect your race, this episode is for you.

If you’re a runner dealing with a stress fracture, you’ve probably been told to “just stop running” and come back in six to eight weeks. But that advice completely ignores the way runners think. In this episode, Dr. Christopher Segler is going to walk you through the crucial questions every runner with a stress fracture should be asking—but that most doctors never do. We’re talking about what might actually be slowing your healing down, what you could be doing right now to maintain your running fitness, and what objective metrics you should be tracking so you know exactly when it’s safe to do more. Because if you want to heal fast and get back to running, you need better questions—and better answers. 

When does a metatarsal stress reaction actually show up on imaging? In this episode of the Doc On The Run Podcast, Dr. Christopher Segler explains the difference between a stress response, stress reaction, and true stress fracture—and why timing matters when choosing X-rays, MRI, ultrasound, or CT scans. Learn how early imaging can help you make smarter race decisions, avoid false reassurance from a “normal” X-ray, and protect your fitness without turning a minor stress reaction into a full fracture.

Can you still run a race if you have a stress fracture—or will it permanently set you back? In this episode of Doc On The Run, Dr. Christopher Segler answers the most urgent question injured runners ask when a big event is approaching: can I still run my race with a stress fracture? You’ll learn how to assess risk, distinguish pain from damage, and make a clear decision without sabotaging your long-term recovery.

How much walking is too much when you have a tibial stress fracture? In this episode of Doc On The Run, Dr. Christopher Segler breaks down how runners can safely stay active while healing, explains the key differences between Fredrickson Grade 1 and Grade 2 tibial stress fractures, and outlines the two critical factors that determine how fast you can recover—without making the injury worse.

Today I was on a strategy call with an injured, but recovering runner who is trying to figure out how to organize his workouts to get strong quickly, without re-injuring his stress fracture.

He was headed in the right direction, but was making a critical mistake when trying to do more with split workouts. It’s not about splitting workouts. 

It's all about the stressors that are applied to the stress out bone. But this also applies to other overtrain injuries like Achilles tendinitis, perennial, tendinitis, or plantar plate sprains.

If you understand, this basic principle, you will definitely get back to running a whole lot faster!

Today on the Doc On The Run podcast, why any runner with any overtraining injury should focus on making sure there are no big stressors on the same structures.

The Walk-Run Routine is likely the most overprescribed and least understood plan for returning to running after an overtraining injury like a metatarsal stress fracture for a plantar plate sprain. 

But the commutative forces that result from that specific routine may put your foot at unnecessary risk of re-injury. Understanding how and why those unique stresses happen may help you make better decisions about your first few runs after you feel your stress fracture or plantar plate sprain has healed enough to resume running. 

Today on the Doc On The Run podcast, we're talking about the worst thing about walk run routine after running injury.

Kettlebell workouts can be a great way to maintaining strength, even if you have a running injury. 

If you are a runner who has an overtraining injury like a metatarsal stress fracture or a plantar plate sprain, you are probably doing everything you can to keep the rest of your running body strong, while that one injured part heals. 

Kettlebell training can help, as long as you don’t let those kettlebell workouts overload that injury to the ball of the foot.

You have to pay close attention to form and technique. Today on the Doc On The Run podcast, we're talking about Kettlebell mistakes and modifications for injured runners.

This morning I was on a webcam call with a runner who had healed a fracture and started running again. He has been running every Monday, Wednesday and Friday, with cross-training in between.  

Now he is ready to add a fourth running workout to his weekly training schedule. 

The question is: 

“What day of the week is best to add an additional run, because I want to make sure I don’t overload the healing tissue and re-injure it.”

Today on the Doc On The Run podcast, we're talking about which weekday is best to add workouts for injured runners.
