Which calf muscle did you strain?
Your calf is two main muscles layered on top of each other. The gastrocnemius is the big superficial one that gives the calf its shape, and it crosses both the knee and the ankle. The soleus sits underneath it and crosses only the ankle. Which one you have torn changes how you test it, how you rehab it, and when you get back.
| Feature | Gastrocnemius strain | Soleus strain |
|---|---|---|
| Where it hurts | Upper calf, near the knee crease | Deep lower calf, closer to the Achilles |
| How it happened | Sudden sprint, jump, or change of direction | Gradual onset during sustained running |
| Pain test | Calf raise with straight knee hurts | Calf raise with bent knee hurts |
| Common age group | All ages, especially explosive athletes | Over 25, endurance athletes |
| Typical return | 3–6 weeks | 4–8 weeks (often underestimated) |
Grading your strain
1–3 weeks
Grade 1 return
Mild, tightness with no power loss
4–8 weeks
Grade 2 return
Moderate, pain and weakness, limping
3–6 months
Grade 3 return
Severe, a complete tear, may need surgery
The calf raise test: your return-to-play benchmark
Before you go back to running you want 25 single-leg calf raises on the injured side, to the same height as the good side, with no pain. For match play, aim to match the good side across three testing days in a row.
Return-to-running progression
Walk normally without pain
Weeks 1–2
If you are limping, you are not ready to progress. Walking should be completely pain-free with a normal gait pattern.
Light jogging
Weeks 2–3
Start with 5 minutes of easy jogging on flat ground. Increase by 5 minutes per session. No pain during or the morning after.
Running at 70–80%
Weeks 3–5
Increase pace progressively. Include gentle curves and changes of direction. Monitor for any tightness.
Sprint and sport-specific
Weeks 5–7
Full-speed sprinting over 20–40 metres, repeated sprint bouts, rugby-specific drills. Must complete two full training sessions before match clearance.
