The Achilles tendon connects your calf muscles to your heel, and it takes a huge amount of load every time you run, jump, or push off, several times your body weight with every stride. When it’s overloaded, it doesn’t always announce itself as a dramatic injury; often it’s a slow-building ache that athletes push through for weeks.
Tendinopathy vs. rupture
Most Achilles problems are tendinopathy: a gradual overuse injury from too much load, too fast, without enough recovery. It’s common in runners increasing mileage quickly and in sports with a lot of jumping and sprinting. A complete rupture is a different, more serious injury, usually sudden, often described as feeling like being kicked in the back of the leg, and it needs immediate medical attention.
Why Achilles tendinopathy is easy to ignore at first
Early on, it often just feels stiff in the morning or at the start of a run, then loosens up as you warm up. That pattern tricks a lot of athletes into training through it, which is exactly how a manageable issue turns into a chronic one that takes months to resolve instead of weeks.
What treatment actually involves
Achilles tendinopathy responds well to a structured loading program, specific exercises that progressively load the tendon to stimulate it to heal and adapt, not just rest and stretching. Training volume usually needs to be adjusted temporarily while this happens, and addressing contributing factors like calf strength, ankle mobility, and running mechanics matters as much as treating the tendon itself.
When to get it checked
See someone if you have persistent Achilles stiffness or pain that isn’t improving after a couple of weeks, pain that’s affecting your running or training, or especially any sudden sharp pain or a popping sensation, which could indicate a partial or complete rupture and needs prompt assessment.
Getting assessed in Calgary
We assess where you are on the tendinopathy spectrum, identify what’s driving it, whether that’s training load, mechanics, or strength, and build a progressive plan to get the tendon handling your sport again.
