Hamstring Rehab • Return to Running
Why the calendar isn't the whole story.
Return to running is one of the biggest milestones in hamstring rehabilitation — whether after a grade II strain or a complete rupture requiring surgery. But it shouldn't be prescribed by a date on a calendar. The real question is: has the athlete earned the right to run? Our approach is built on progression by competency, not weeks since injury.

The Problem With Timelines
Returning to running following a hamstring injury should not be based solely on time since injury. Two athletes can both be eight weeks post-injury and be nowhere near the same level of readiness. One may have full strength, no pain and clean running mechanics; another may still have pain, a significant strength deficit and poor tolerance of loading. Treating them identically because of the same post-injury date does not make sense.
Research by Fearghal Kerin and colleagues, demonstrates that hamstring injuries can have very different rehabilitation timelines depending on their anatomical characteristics. In professional rugby players, injuries involving the intramuscular tendon were associated with a substantially longer time to return to full training than injuries without tendon involvement.
This is why rehabilitation should be individualised rather than dictated by a fixed timeline — and why the decision to run should be criteria-led, not calendar-led.
Evidence-Led Frameworks
The published work of Matthew Buckthorpe and colleagues has shaped how modern sports medicine handles return to running after hamstring injury. A few principles stand out:
Running itself should be used as a rehabilitation tool, introduced early in controlled doses — not withheld until the end of rehab and then "switched on".
Progression through the running programme should be governed by objective criteria — pain response, strength, and tolerance of the previous stage — not by a predetermined number of sessions.
Sprinting places the greatest demands on the hamstring. A controlled jog does not demonstrate readiness for high-speed running — speed must be rebuilt progressively, stage by stage.
Rehabilitation should progressively expose the athlete to the demands of their sport — accelerating, decelerating, changing direction and repeating efforts under fatigue.
The Physio Tullamore Model
Our hamstring rehabilitation model doesn't ask "how many weeks has it been?" It asks "what does your sport demand, and what can your body currently do?" Here's how it works:
We establish the objective physical and movement demands of your sport — at your level. Sprint speeds, repeated-sprint volumes, acceleration/deceleration loads and movement qualities of a senior club, academy or county athlete are not the same. Your targets come from that profile, not a generic protocol.
We rebuild your physical capacity and conditioning back to that level — eccentric hamstring strength, high-speed force production, tissue tolerance and repeated-effort conditioning — measured objectively at every stage, not assumed.
Working on the technicalities of how you move: stride mechanics, posture, ground-contact strategy, acceleration and deceleration technique. Passing a strength test while running with compensations is not ready — how you run matters as much as whether you can.
This is underpinned by our Biomechanics Screening and Running Biomechanics assessments, with speed profiling via Speed Gates & Biomechanics.
The Progression
Once the criteria are met, running is reintroduced through a structured speed and exposure ladder — progressing only when the previous stage is tolerated:
Controlled jogging & tempo runs
Strides & progressive acceleration
High-speed running
Maximal sprinting
Sport-specific running under fatigue
Response is monitored throughout: pain during or after running, and symptoms the next morning, tell us whether the previous workload was tolerated or whether the programme needs modifying. The response to running is a criterion in itself.
Criteria Before Running
Kerin's research into return-to-high-speed-running decision-making supports a multidimensional, criteria-based approach. Before running is introduced, the athlete should demonstrate:
Minimal or no pain during everyday activities and rehab exercises. The absence of pain is considered an important criterion by the majority of elite practitioners — it should not be ignored because a particular date has arrived.
Strength progressively restored, with particular attention to eccentric hamstring strength — a key criterion when progressing towards high-speed running, built from controlled strength work towards demanding eccentric loading.
Running introduced gradually — lower speeds first, then faster running, acceleration and sprinting — progressively exposing the athlete to both internal and external training loads.
A major milestone: reaching high or near-maximal running speeds without pain or adverse symptoms — essential in Gaelic games, where athletes repeatedly accelerate, decelerate, change direction and sprint.
The Checklist
Before running begins — and before progressing each stage — we ask:
If the answer to any of these is "no", the athlete isn't behind schedule — the criteria simply haven't been met yet.
Real-World Example
In April 2026, Westmeath footballer Luke Loughlin suffered a Grade 4C hamstring tear and tendon rupture during Westmeath's Leinster Championship quarter-final victory over Meath. He required surgery and initially believed he would probably not play football again during 2026.
Instead, in August — just over three months after injury and surgery — he came off the bench for his club, The Downs, and immediately contributed two two-point scores and helped create a goal in a 1-13 draw with Coralstown/Kinnegad.
His return demonstrates why time alone cannot be used as the primary return-to-running or return-to-play criterion. A three-month return following a complete rupture should not be interpreted as an appropriate timeline for every athlete — it shows what is possible when rehabilitation, physical preparation and individual response to loading allow it. His manager also highlighted the significant prehabilitation and rehabilitation work completed around the surgery.
Loughlin's experience should be viewed as an individual case study rather than a target timeline. Significant hamstring injuries have highly individual recovery timelines; successful return depends on the capacity to tolerate progressively increasing loads — not the number of weeks since surgery.
Key Takeaway
Return to running after hamstring injury should be a progression rather than a single date. The question should not simply be "How long has it been since injury?" The more appropriate question is:
“Has the athlete demonstrated the physical capacity to tolerate and repeatedly perform the demands of running and their sport?”
Return to running is therefore not the final goal. It is one important step towards the ultimate objective: a safe and successful return to performance.
