Why Does My Achilles Hurt During Marathon Training?

Achilles pain during marathon training can show up as a sharp or aching feeling while you run, especially as repeated mileage strains the tendon.

If your Achilles starts hurting during marathon training, the timing of the pain can tell you a lot about what is happening. You may feel fine when you begin a run and then notice the tendon becoming sore as the miles build, especially when your training includes longer runs, hills, faster sessions, or a sudden increase in mileage. The Achilles tendon works every time you push off the ground, so a demanding training schedule can repeatedly stress the same area.

As the tendon becomes tired during a longer training session, it may not move as comfortably as it did at the beginning of your run. That repeated demand can leave the area less flexible and more sensitive, making each additional mile harder on an Achilles that is already being stressed.

More Miles Keep Asking Your Achilles To Push Off

Every running stride makes your Achilles tendon help propel you forward.

During marathon training, your Achilles has to handle that job over and over for much longer distances than during an ordinary run. As the mileage accumulates, repeated push-off can place more strain on the tendon, especially when you are also adding hills, speed work, or longer training runs.

The Pain Becomes More Noticeable As Your Run Goes On

A tired Achilles can become more painful as repeated strides add up.

You may start a training run with little or no pain and then notice the Achilles becoming sore, tight, or increasingly uncomfortable several miles later. The tendon is continuing to work with every step, so fatigue and accumulated stress can make the original irritation much more noticeable as the workout continues.

Why Your Achilles Keeps Hurting During Training

Your Achilles has a hard time healing when blood flow and circulation are limited.

Tendons, ligaments, and other soft tissues naturally receive less blood supply than many other parts of the body. Because of this, they often take longer to heal after repeated stress or injury, leaving you more vulnerable to lingering pain and a cycle of reinjury.

When circulation through the area remains limited, injured tissues have a harder time receiving the vital oxygen and nutrients they need to repair and heal. This can leave your Achilles feeling stiff, tight, weak, or painful during everyday movement and activity.

What Can Help Your Achilles Feel Better

Your Achilles starts feeling better when blood flow and circulation improve.

Chinese herbs have been used for centuries to promote healthy blood flow and circulation. Their medicinal properties help break up stagnant blood and fluids that remain trapped around injured tissues, interfering with circulation. As circulation improves, blood flows more freely through the area, allowing those tissues to receive the oxygen and nutrients they need to heal properly.

Topical herbal remedies made with these Chinese herbs can help relieve pain while improving blood flow and circulation to injured tissues. The right product depends on your symptoms and whether you're in the acute or chronic stage of recovery.

If you have pain, swelling, inflammation, or bruising, Acute Sinew Liniment helps relieve these symptoms by increasing circulation and dispersing stagnant blood and fluids around the injured area to speed recovery. During the acute stage of healing, getting circulation moving early allows injured tissues to receive the fresh blood, oxygen, and nutrients they need to repair and heal.

If your injured area is especially swollen, red, or warm to the touch after a recent injury or flare-up, Sinew Herbal Ice is also used to reduce swelling and inflammation while restoring normal circulation so you can quickly regain range of motion. While traditional ice is commonly used to reduce swelling, Sinew Herbal Ice acts as an ice alternative to reduce swelling and inflammation while also dispersing accumulated blood and fluids to speed the healing process.

If you no longer have swelling or inflammation, but still have pain, stiffness, weakness, or sensitivity in cold and damp weather, Chronic Sinew Liniment helps relieve these symptoms by strongly stimulating circulation and increasing blood supply to injured tendons and ligaments to promote their healing. This is especially important because tendons and ligaments naturally receive less blood supply, which is why chronic injuries can take longer to heal.

If you have residual pain and stiffness, or the area becomes more painful in cold weather, Sinew Injury Poultice is also used to significantly stimulate circulation to injured tendons and ligaments to further promote their healing. By strongly increasing circulation, it counteracts the reduced blood flow caused by cold weather that commonly aggravates chronic tendon and ligament injuries.

If you exercise, play sports, or do other strenuous activities, Sinew Sports Massage Oil warms and stimulates muscles for exertion and relieves muscle tightness and soreness after activity. Warming and preparing your muscles before activity can improve flexibility, enhance performance, and reduce the risk of injury.

Frequently Asked Questions

You may also find these commonly asked questions helpful.

Why Does My Achilles Hurt During Marathon Training?

Your Achilles may hurt during marathon training because repeated running keeps stressing the tendon, especially as mileage, long runs, hills, or speed work increase.

Why Does My Achilles Start Hurting During A Long Run?

Your Achilles may become painful later in a long run because repeated strides and push-off continue adding stress to the tendon as the miles build.

Can Increasing Marathon Training Mileage Cause Achilles Pain?

Yes. Increasing your mileage can place more repeated demand on the Achilles, particularly when your training volume rises faster than the tendon can comfortably handle.

Why Does My Achilles Hurt More As I Keep Running?

Your Achilles can become more painful as you keep running because fatigue and repeated strain can make an already irritated tendon increasingly sensitive.

Why Does My Achilles Feel Tight During Marathon Training?

Your Achilles may feel tight when repeated running leaves the tendon less flexible and increasingly stressed during your training session.
