Return to Running After Injury: Structured Walk-Run Session

Session Overview

A conservative, structured walk-run reintroduction for triathletes returning to running after injury or a prolonged break — cleared by a physio or doctor for gentle load, but not yet ready for continuous running. This session prioritises pain-free tissue loading over pace or distance.

What You’ll Need

• A flat, even surface — a track, park path or treadmill (avoid trails or cambered roads for this early stage)
• A stopwatch or interval timer
• Written clearance from a physio or doctor if you’re returning from a diagnosed injury, not just general deconditioning

Warm-Up (5 minutes)

Walk briskly for 5 minutes, gradually increasing pace, followed by a few dynamic leg swings and ankle circles. Do not stretch cold or static-stretch an area that’s still recovering — save static stretching for after the session if at all.

Main Set

Alternate short, easy running intervals with longer walking recoveries. Run efforts should feel genuinely easy — RPE 3-4 out of 10, well below any pace where you’d notice the previously injured area. Stop the session immediately if you feel sharp pain (dull, general fatigue is expected and fine; sharp or localised pain is not).

• 8 x (1 minute easy run, 2 minutes walk)
• Total running time: 8 minutes across the session
• If all 8 reps feel completely pain-free, next session try 8 x (90 seconds run, 90 seconds walk) — increase run time only, keep walk recovery generous until you’re consistently pain-free

Cool-Down (5 minutes)

Walk easily for 5 minutes to bring heart rate down gradually, then gentle static stretching of calves, hamstrings and hip flexors if the recovering area tolerates it comfortably.

Coaching Notes

• Progress run time, not run pace — the temptation to “test” the injury with a faster effort is exactly what derails a return-to-run plan
• Leave at least 48 hours between walk-run sessions early on, and monitor how the area feels the following morning, not just immediately after — delayed soreness is common and worth tracking
• A short-term setback (a session that doesn’t feel right) is normal and doesn’t mean starting over — simply repeat the previous week’s volume rather than progressing, and don’t push through
• This is a general template, not a substitute for individualised physio guidance — return-to-run protocols vary significantly by injury type (bone stress injury timelines are very different from a tendon or muscle strain)
