Your gastrocnemius, the surface calf
The big muscle you can see. It crosses the knee and the ankle and it powers push off. Often tight. Often blamed. Often doing too much.
Achilles & Calf Self-Assessment
Achilles Pain That Will Not Settle? Start Here.
You backed off. You stretched the calf. And the tendon still grumbles every morning and every push off.
Here is the truth most runners never get told. It is rarely the Achilles that is the problem. The Achilles is a spring. It handles five to seven times your bodyweight with every single stride. It only overloads when the muscles that should be sharing that load go quiet.
Your Achilles is caught in the middle. When the calf and the chain above it do their jobs, the tendon springs. When they do not, the tendon takes tension it was never meant to hold.
The Basics
Meet The Team Around Your Achilles
Keep this simple. A few key players decide how your Achilles feels.
Your soleus, deep in the calf
It accepts load every time your foot hits the floor at midstance. When it goes quiet, that load travels straight into the tendon instead.
Your hamstrings and glutes
When their load tolerance drops, the calf and Achilles pick up the slack lower down. In clinic this is the hidden driver we find again and again.
When these share the work, the Achilles springs and recovers. When the calf tightens and the soleus and hamstrings go quiet, the tendon carries the tension on its own. That is when it starts to complain. Most of what you will do on this page is about getting that load off the tendon and back into the muscles that should hold it.

What Does Your Achilles Actually Feel Like?
Pick the one that fits you best. It points you to the right checks below.
01Check First
Sudden sharp pain
It felt like a blow, or like being kicked in the back of the leg, and you cannot push off or rise onto your toes.
Start with the pathology checks 02CoordinationGrumpy in the morning
Stiff and sore at the first steps or the start of a run, warms up mid session, aches after.
Go to coordination 03CoordinationTight calf, sore push off
A tight or aching calf and pain driving off your toes, worse with hills or speed.

Pathology Assessments
Achilles Tendon Assessment: Signs You Need A Professional
Is It Something To Get Checked?
Before anything else, we rule out the things that need a professional eye. These checks do not diagnose anything. They tell you whether it is sensible to get it looked at before you load it.
The Single-Leg Heel Raise Screen
A tendon that cannot take your bodyweight through a simple heel raise is telling you something. Here is a simple way to screen it at home.
- Stand next to a wall or rail and hold it for balance only.
- Stand on the sore leg on its own.
- Rise up onto the ball of your foot, as high as you can, then lower slowly. Try for up to ten.
You can rise and repeat
You get up onto your toes, pain stays low and settles. Capacity looks fine. Move on to the coordination checks.
You cannot, or it is sharp
You cannot rise onto your toes, it is sharply painful, or the tendon looks or feels thickened next to the other leg. That is a flag. Stop, and get it assessed before you load it.
What you are looking for. Watch whether you can get up onto your toes at all, how the pain behaves, and how the tendon looks compared to the other side.
The Red Flag Check
Some signs mean stop and get it looked at. Tick any of these and book an assessment.
- Sudden sharp pain that felt like a blow or like being kicked in the back of the leg.
- You cannot push off or rise onto your toes.
- Visible swelling or a thickened appearance to the tendon.
- Morning stiffness that is getting worse week on week, not better.
- Sharp pain at one specific point on the tendon that stops you running.
A word on a sudden blow. A sharp, sudden pain low on the tendon with a loss of push off can signal a tendon tear. That needs urgent assessment, not a wait and see. Most Achilles pain is not this. But if it fits, get seen quickly.
When in doubt, get it checked.
These checks are for peace of mind and understanding your body. They are not a diagnosis and they do not replace medical advice. If your pain came on like a blow, you cannot rise onto your toes, or the tendon is visibly thickened, stop training and see a doctor or physio.
If nothing above fits you, your Achilles pain is far more likely a load and coordination story. That is good news, and it is exactly what the next part is for.
Coordination Assessments
Is Your Body Sharing The Load?
No red flags? Then the question changes. It is not "what is damaged". It is "who has stopped doing their job". This check shows you whether the back of your chain is sharing the load, or leaving it all to the calf and the tendon.
The Midfoot Bridge Check
This is the one to start with. It tells you whether your soleus and hamstrings will accept load without your back or your quads taking over.
- Lie on your back, knees bent, feet flat, weight on the balls of your feet.
- Lift your hips just an inch off the floor. That is all. Not a big bridge.
- Hold that tension through your midfoot and feel where the work is.
A good result
You feel the work in your hamstrings and deep in your calf. Your hips stay level. You can hold it without arching your lower back.
A poor result
The work dumps into your lower back, or into the front of your thighs. Your weight rolls back to your heels. Your hips drop or twist. This is the pattern that keeps loading your Achilles. It is also exactly what the drills below retrain.
Get The Basics Right
The Drills
These are the exact drills we use in our clinics to get the team around the Achilles working together again. Do them in order. Each phase earns the next. Keep everything pain free.
1
Isometrics
Wake it up.Midfoot Foam Roller Bridge
Restores the connection between your foot, ankle, knee, and hip, so force transfers cleanly through the whole chain.
Cue. Push through the ball of your foot, hips only an inch up. Do not let your weight roll back to your heels.
2
Load Tolerance
Share the load.Midfoot Bridge with Hip Shifts
Teaches your nervous system it is safe to hold load through the midfoot while adding controlled side to side movement.
Cue. Stay just an inch off the floor. Keep contact through the ball of your big toe as you shift.
New drill
Anterior Hip Loading
Trains the whole front line, from your toes to your ribs, to tolerate load as the hip extends. That is the exact moment the calf and Achilles get overloaded when the front line goes quiet. It builds the deceleration capacity that keeps the tendon out of trouble at end range.
Cue. Push through your toes with your elbows locked. Lower the knees toward the floor first, then drive the hips forward. Do not bend your elbows to cheat the load, and back off the depth if you feel your lower back.
Soleus Slouch
Restores the co-contraction around the knee so the hip can do more of the work.
Cue. Slight knee bend, weight over the midfoot, neck and shoulders relaxed. Do not let the knee snap back or your weight drift to your heels.
3
Deceleration Tolerance
Control it.Slouch Walking Lunges
Takes the co-contraction and adds movement through space, the way real sport demands.
Cue. Stay low in the tunnel, do not stand up between steps, keep the upper body relaxed.
New drill
Peroneal Bracing
Builds control on the outside of your lower leg and ankle, the stability real ground actually demands. Uneven surfaces and side on load stop catching the tendon out.
Cue. Stand on one leg, ribs over your midfoot, a hand on the wall for light support. Shift to the outer edge of your foot and back, slow and controlled. Do not lean so far you lose control, and keep midfoot pressure between shifts.
Progress
Achilles Pain Recovery: How To Know The Drills Are Working
The push off starts to feel springy again, not braced.
You feel the work shift into your soleus, hamstrings and glutes, not the tendon.
The morning stiffness eases, and the tendon warms up faster.
The tendon feels no worse the next day. That is the rule that matters.
When to progress
When a drill feels easy and clean, move to the next phase. Easy is the signal. If it still feels like a fight, stay where you are.
When to get help
If the pain is not settling after a couple of weeks of honest work, if the tendon feels worse the day after every session, or any red flag from the pathology checks shows up, get it assessed.
Your Sport
Achilles Pain By Sport: Running, Hyrox, CrossFit and Gym
Running and marathon
The Achilles handles five to seven times your bodyweight every stride. Ramp mileage or intensity too fast and the spring cannot recover at the same rate. This is the most common Achilles injury we treat in athletes training for a first marathon or triathlon. Share the load down the chain and the tendon copes.
Hyrox and CrossFit
Deep squats and lunges push the ankle into dorsiflexion, straight into the calf and Achilles complex at the bottom of the movement. If the tendon is already sensitive, forcing depth or heavy load flares it. Modify depth, elevate the heel, and keep the surrounding muscles strong rather than resting them off.
Gym and lifting through a niggle
Do not let the calf and Achilles atrophy while you wait. Reverse lunges and split squats load the tendon more kindly than forward lunges. If full range calf raises hurt, mid range isometric holds can settle the tendon while you keep strength.
