Most running setbacks happen because people base their return on symptom resolution alone, not tissue capacity.
Running produces 2â5Ă bodyweight of ground reaction force with every step.â¨Over a 5km run, thatâs 6,000â7,000 high-load repetitions.
Pain tells you how something feels.â¨Load tolerance tells you what your tissues can handle.â¨These are not the same thing.
A safe and effective return-to-running plan considers:
1. Tissue Capacity
Muscles, tendons and bone adapt to load through mechanotransduction.â¨When load is reintroduced too quickly, microdamage exceeds repair = irritation, inflammation, flare-ups.
2. Strength Thresholds
Research shows that deficits in calf, quad, hip and trunk strength increase running-related injury risk.â¨Strength must meet the demands of impact loading before running begins.
3. Impact Management
Factors like cadence, stride length, footstrike and running surface influence loading rate.â¨ie - A higher cadence (165â180) reduces tibial shock and joint loading.
4. Progressive Loading
Your tissues respond best to gradual, predictable load exposure.â¨Alternating walkârun intervals, spacing recovery days and tracking RPE all help manage cumulative stress.
5. Symptom Behaviour
We expect some discomfort.â¨What matters is:
* Does it settle within 24 hours?
* Is irritability low?
* Is there increasing tolerance week to week?
Pain â damage.â¨Capacity â comfort.â¨
Running readiness sits in the interaction between the two.
A structured return-to-running plan isnât conservative ââ¨itâs scientific stress dosing to rebuild durability, reduce recurrence and keep you running long-term
