Description of intervention(s) / exposure
Participants will be asked to participate in four consecutive Saturday parkruns, supervised by a member of our research staff. The project will take place in Southern Tasmania, utilising the weekly parkrun event on the Queens Domain.

parkrun is a 5 km volunteer led community run/walk event held weekly on Saturday mornings all around the world. Participants receive a barcode upon registration which is matched to a finishing position and run time. Each registered individual receives an email with their personal result and all runners’ results are published publicly on the parkrun website each week. Participants in parkrun consist of a broad demographic of people including walkers, joggers and runners and include a wide variety of ability levels from people starting their fitness journey to elite level. In this study, participants will be asked to walk in four (preferably consecutive) parkrun events, supervised by a member of our research staff. Participants will be able to end their participation in each event early if they are unable to complete the full 5 km.

An exercise physiotherapist with >3 years’ experience in supervising group exercise sessions will be present at all parkrun events and will ensure the exercise is performed safely. Physiotherapists are qualified to advise patients about recognising an “unsafe” symptom exacerbation – using an 11-point numeric rating scale (NRS-11) to score walking pain. If symptoms rise above unsafe levels, participants will be advised to rest and the intensity will be reduced appropriately.

Adherence will be monitored by attendance at each individual parkrun. If a participant does not attend one of the parkrun's they will be contacted to determine why they did not attend and if they are continuing with the study. If a participant chooses to withdraw from the study, some brief questions about why (detailed in our early withdrawal script) will be asked and recorded with participant permission. Our physiotherapist will be in attendance at each parkrun to encourage participants and ensure their participation in the event is safe.

Outcomes
Primary outcome [1] 307405 0
Feasibility: Determined by participant adherence, attendance and/or study completion rates. Attendance will be recorded at each parkrun by research staff. Adherence will be measured by the number of parkrun's each participant attends and whether they are sequential. Study completion rates will be determined by the number of participants who complete all 4 parkrun's during the study.
Timepoint [1] 307405 0
Before, during and after each individual parkrun, and at the post-intervention interview approximately 1 week after the participant has completed their fourth parkrun.
Primary outcome [2] 307406 0
Acceptability of parkrun to knee osteoarthritis patients. Acceptability will be assessed by qualitative measurements of enjoyment using the Physical Activity Enjoyment Scale, reporting confidence in completing the upcoming parkrun on a visual scale of 1 through to 10, and levels of exertion using the Borg Perceived Exertion Scale.
Timepoint [2] 307406 0
Before and after each individual parkrun, and at the post-intervention interview approximately 1 week after the participant has completed their fourth parkrun.
Primary outcome [3] 307407 0
Safety: Measured by the number of adverse events recorded throughout the duration of the study.
Potential AEs from this study include increased knee pain or pain at other sites, temporary muscle stiffness, falls or other injuries related to the exercise. Falls or injuries that occur during the intervention will be recorded by our physiotherapist. Knee pain will be recorded before and after each individual parkrun event using a 100mm visual analogue scale. Participants will be encouraged to contact the researchers should they have any concerns about injuries or pain and any adverse events that are reported in this way will be recorded.
Timepoint [3] 307407 0
Adverse events (AE) will be monitored throughout the study. AEs will be defined as any intervention-related problem that lasts for >2 days and/or caused the patient to seek other treatment. Potential AEs from this study include increased knee pain or pain at other sites, temporary muscle stiffness, falls or other injuries related to the exercise. There is a very rare chance of an exercise induced heart attack or case sudden death. In the case of an AE, participants will be advised to rest and reduce activity. Research staff will be present at the parkrun events to support participants and assist should any safety issues arise.
Secondary outcome [1] 351864 0
Function and stiffness: Function and stiffness will be assessed using the Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC).
Timepoint [1] 351864 0
WOMAC will be used at baseline and post-intervention interview approximately 1 week after the participant has completed their final parkrun.
Secondary outcome [2] 351865 0
Enjoyment: Physical activity enjoyment will be assessed using an adaptation of the Physical Activity Enjoyment Scale.
Timepoint [2] 351865 0
After each individual parkrun and at the post-intervention interview approximately 1 week after the participant has completed their fourth parkrun.
Secondary outcome [3] 351866 0
Exertion: Levels will be measured using the Borg rating of perceived exertion scale.
Timepoint [3] 351866 0
After each individual parkrun.

Summary
Brief summary
Participating in physical activity reduces pain and improves function in knee osteoarthritis (OA) patients. Despite this, only 13% of people with knee OA meet the current physical activity guidelines, far lower than the national average. Identifying effective, low-cost, accessible, scalable and sustainable strategies to promote physical activity in knee OA patients is crucial. ‘parkrun’ is a free weekly mass community event that represents a novel setting with substantial untapped potential for physical activity promotion. The aim of this study is to assess the feasibility, acceptability and safety of parkrun for patients with knee OA. Participants will be asked to participate in four consecutive Saturday parkruns and complete quantitative and qualitative interviews about their experience. Participants will be followed-up after 6 months to assess longer-term impacts and adherence. Study findings will inform the development of a large RCT aiming to examine parkrun as a strategy to promote physical activity for knee OA and study its effectiveness compared to usual care.

This will be the first study to examine parkrun as a novel physical activity promotion strategy for knee OA patients. This is a group of patients in need of innovative strategies to promote physical activity participation. Given the “parkrun phenomenon” has hit 17 countries around the world and consists of 400,000+ Australian members, this project has potential for broad national and international implementation.
