Injured Before Your Marathon? Here’s How to Respond

All our injury and recovery resources are rigorously vetted by our expert team and adhere to our Injury Guidelines.

It is every marathoner’s worst nightmare: you put in all the hard work and sacrifice to train for your race and then become injured before your marathon

Then the questions swirl and the bargaining begins. Can you still run your marathon? Maybe you can run if you ditch your A goal? Maybe you can pick a race that is a month later? 

Unfortunately, many runners ignore the red flags that they need to stop training for a marathon and focus on recovery—and become worse for wear. 

This happened to me personally when I was diagnosed with a partial hamstring tear ahead of my 2019 marathon. I continued to rigorously train while getting physical therapy, only to not be able to run for an entire year after my race.

Then not six months later of finally returning to running, I was diagnosed with a plantar fascia tear. Not wanting history to repeat itself, I immediately cancelled my 2021 marathon entry and focused on recovery

However, whether you can still race when you become injured before your marathon is not black or white. There are many variables such as what type of injury you have and how much time remains before your marathon. 

This is why we got with experts Todd Buckingham, an exercise physiologist at Mary Free Bed Rehabilitation Hospital, and Joe Norton, a doctor of physical therapy, to make the decision as clear as possible for you, should you become injured before your marathon. 

In this article, we will cover:

  • What to do if you become injured before your marathon,
  • What type of injuries you can still run with,
  • What type of injuries require you to cancel your marathon,
  • How to tell if you need to stop running,
  • How can you tell what injury you have, and
  • How to mentally cope with cancelling your marathon due to injury.

What should you do if you become injured before your marathon?

Nearly every runner has been there when you wake up with an odd ache or have a sudden pain while running. 

If you become injured before your marathon, Norton says you should:

  • Go see a sports physician, orthopedic doctor, or physical therapist who is familiar with runners to find out what is going on.
  • Develop a treatment plan that includes whether you need to stop running.
  • If you are resting your injury, continue to do non-aggravating cross-training activities such as yoga, cycling, swimming, aqua jogging, or the elliptical.

It is advised to seek medical help when confronted with a running injury. However, if you can’t see a health professional, you should:

  • Stop running, and ice and heat for 20 minutes at least 3 times throughout the day.
  • If it is feeling better after several days of rest, attempt a very easy run.

  • If the pain does not get worse or goes away, you can resume running at 50 percent volume of easy running for several days before resuming training.
  • If the pain gets worse on the run or within 48 hours, you need to stop running for at least a week and reevaluate. 
  • You can continue to train with activities such as cycling, swimming, aqua jogging, or the elliptical.

What type of injuries can you still run with?

Generally speaking, runners can continue to run if they suffer from a mild strain or inflammation such as plantar fasciitis, runner’s knee, or IT band syndrome.

What types of injuries require you to cancel your marathon?

If a runner has an acute injury such as a tear, grade II or III strain, stress fracture, or broken bone, then they cannot continue to run and should cancel their marathon. 

According to Buckingham, here are the injuries you can and cannot run with:

Bone fractures: 

Most fractures heal in 6-8 weeks, but it varies from person to person and bone to bone. 

“Depending on the fracture and if it occurs early in the training cycle, it could be very possible for a runner to complete their marathon training,” Buckingham suggests, saying runners should shift their goals to finishing rather than hitting a personal best since that can set the athlete back even further.

Muscle strains: 

A mild Grade I strain can heal in 3-6 weeks, and training can continue if it does not worsen the pain. 

For more severe strains like a Grade II or Grade III or a muscle tear, the recovery process can take several months and sometimes require surgery to repair the injury. Therefore, runners should cancel their marathon if suffering from an injury of this degree.


Tendonitis can heal in 2-4 weeks, depending on the amount of inflammation. However, chronic inflammation could take 6 weeks or longer to heal.

“Based on the severity and location of the tendonitis, training could continue unless pain is made worse through training,” advises Buckingham. 

For all these injuries, it is important to consult with a health professional prior to continuing training or racing, he advises.

Can you run a marathon if you are injured 4 weeks before? 

There is hope for runners if they are mildly injured early on in the training cycle, but what if it is just one month before? It is still possible, says Buckingham.

“Depending on the type, severity, and location of the injury, it is possible to run a marathon if injured 4 weeks before the race.’ 

Here are the injuries you CAN possibly run your marathon with:

  • A Grade I muscle strain could heal on its own before race day. 
  • Tendonitis (if not painful to run and the goal is to finish, not run a personal best).
  • Stress fracture depending on the severity and location of the fracture (but this is not advisable).

Here are the injuries you CANNOT run your marathon with:

  • A Grade II or Grade III strain 
  • Muscle tear
  • Stress fracture 
  • Broken bone

How can I tell if I need to stop running because of an injury?

You need to stop running due to pain if:

  • The pain does not go away after traditional at-home treatments like ice and heat, and rest. If you treat at home with no improvement for 2 weeks, stop running!
  • The pain causes you to change your gait, putting you at risk for compensatory injuries.
  • The pain gets worse as you run or intensifies within 48 hours of your run.

Buckingham adds that if you continue to run and the pain doesn’t intensify, then running is not making it worse and you can continue to train.

How can I tell what injury I may have?

The location of the pain will be the first indicator, according to Norton. If the pain is acute, it could be a joint or tendon. If it is diffused, it could be a joint. 

The second indicator is how the pain behaves, meaning what makes it worse and what makes it go away. 

  • Tendons and muscles warm-up and improve with activity unless they are torn.
  • Bones get worse with activity.
  • Joints like some mobility but may have a threshold of how much.
  • Hamstrings and calves will be more stimulated with speed activities as they are associated with faster running velocity.

The 1 to 10 pain scale

Norton likes to use a pain scale of 1 to 10 to ascertain if a patient should stop running:

  • If the pain hurts more than a on the pain scale 6, stop running. And if you can’t walk, see a professional!
  • If the pain hurts at a level 5, proceed with caution. If the pain does not improve in 2 weeks of taking it easy, but doesn’t hurt outside of running, take 3 days rest. Then try running at 50 percent of your volume at an easy pace. If it still hurts, see a professional. 
  • If the pain is at a level 2, tread lightly for a couple of days until it is gone. Focus on eating a balanced diet, sleeping, and using heat, ice, massage, compression, to spur healing.

How can I decide if I need to cancel my marathon?

Many runners push through the pain of an injury all because they don’t want to think their hard work is wasted. However, training with an injury is risky and it could lead to more time off in the future. 

Remember, there will always be other marathons and the most important thing in running is longevity in the sport.

  1. I thought I sprained my ankle 2 weeks ago so was just self treating it but then decided since it wasnt improving I hit dr a few days ago. Sure enough I had a small fracture and he put me in a boot. He said I could still run my half marathon which is early december but I do plan to let go of my A goal and just finish it ! Hope all injured people out there are healing well!
