How to Safely Return to Running After Injury – The Atomic PT Progression
Coming back to running after an injury is about more than just waiting until it “feels better.” A structured, criteria-based progression lowers the risk of re-injury, rebuilds confidence, and ensures your body is ready for the demands of running.
Before You Start – Clearance Criteria
You should be able to:
Walk briskly for 30 minutes without pain
Have full, pain-free range of motion at the hips, knees, and ankles
Perform single-leg hops, bounds, and step-downs without pain, swelling, or limping
Have strength at least 80–90% of the uninjured side (can be tested via single-leg strength tests or hop tests)
Tolerate basic plyometric drills (200–250 foot contacts, e.g., jump rope or low-level hops)
The Atomic PT Return-to-Run Phases
Frequency: 2–3x/week, with at least one rest day between run days.
Surface: Start on treadmill or level track, then progress to roads and varied terrain.
Pace: Comfortable conversational pace until cleared for speed work (i.e Zone 2)

Atomic PT Return-to-Run Progression
A structured, criteria-based plan to get you back to running safely after injury.
Before You Start – Clearance Criteria
You should be able to:
Walk briskly for 30 minutes without pain
Have full, pain-free range of motion at hips, knees, and ankles
Perform single-leg hops, bounds, and step-downs without pain, swelling, or limping
Show strength at least 80–90% of the uninjured side
Tolerate 200–250 low-level plyometric foot contacts (e.g., jump rope)
Phase 1 – Walk/Run Intervals
Goal: Reintroduce running gradually while maintaining good form.
Session 1: Walk 4 min / Run 1 min – Repeat 4–6 times – Total 20–30 min
Session 2: Walk 3 min / Run 2 min – Repeat 4–6 times – Total 20–30 min
Session 3: Walk 2 min / Run 3 min – Repeat 4–6 times – Total 20–30 min
Session 4: Walk 1 min / Run 4 min – Repeat 4–6 times – Total 20–30 min
Progression rules: Advance to the next session only if pain-free during and after, no swelling, and no change in running mechanics. Rest or cross-train between run days.
Phase 2 – Continuous Running
Goal: Build steady running volume at an easy pace before adding intensity.
Starting point: Begin with 10–15 minutes continuous running at a conversational pace.
Progression rate: Increase time or distance by no more than 10–20% each run.
You can increase after each successful run or hold for 2–3 runs before increasing, depending on tolerance.
Frequency: Run 2–4 days/week with at least one rest or cross-training day between runs.
End goal: Comfortably run 30–40 minutes continuously, pain-free, with good form.
Move to Phase 3 when you can hit target time for 2–3 runs in a row without symptoms or gait changes.
Phase 3 – Volume Build
Goal: Return to baseline mileage without speed or hills.
Increase weekly mileage by 10–30% depending on injury type, history, and tolerance.
Add an extra run day only if tolerated.
Keep long run under 40% of total weekly mileage.
Continue to rest or cross-train between hard days.
Step back in mileage if soreness lasts more than 24 hours, if pain alters gait, or if swelling returns.
Phase 4 – Return to Full Training
Goal: Safely reintroduce higher-load elements like speed and hills.
Add hills once you reach 50–60% of pre-injury mileage without symptoms.
Introduce short strides (20–30 seconds) 1–2x/week on flat ground.
Progress to full workouts, hills, and race-pace running once you’re at 75–80% of pre-injury mileage.
Maintain recovery days and cross-training to avoid overload.
.Additional Key Points
Always warm up with dynamic mobility drills and activation exercises
Keep easy pace until tissues adapt; speed work comes last
Cross-train to maintain cardiovascular fitness during build-up
Use pain as a guide: mild discomfort during running is acceptable if it resolves within 24 hours and does not alter your gait
