parkrun and Cardiac Arrest: Your Guide to Getting Started

parkrun is a free, weekly 5K event held every Saturday morning at hundreds of locations across the UK and around the world. You can walk, jog, or run — at whatever pace suits you, on that particular day. There is no last place, no pressure, and no cost. For cardiac arrest survivors, it has become one of the most widely recommended and widely loved parts of recovery.

This page covers everything you need to know: the evidence base for parkrun in heart conditions, the safety measures that make it appropriate for survivors, real stories from our community, how to join the SCA UK parkrun group, and how to get started if you’re not sure you’re ready yet.

What is parkrun?

parkrun is not a race. It is a timed 5K event, but the time is only there if you want it. Many participants walk every single week. Many others alternate between walking and jogging. Some run competitively. All of them cross the same finish line, get the same barcode scanned, and count as a parkrunner.

Events take place every Saturday at 9am (junior parkruns on Sundays). They are organised entirely by volunteers, are free to enter, and are held in parks, green spaces, and paths in communities across the country. All you need is a free registration and a printed or digital barcode. You can find your nearest parkrun at parkrun.com.

The Evidence for parkrun in Heart Conditions

A study published in the journal Open Heart examined how people with heart-related conditions participate in and benefit from parkrun. The findings were striking. Among participants with heart conditions who regularly attended parkrun, the research found significant improvements across multiple dimensions of health and wellbeing:

Importantly, the study found that for people with heart conditions who initially exercised fewer than three days per week when they first registered for parkrun, nearly half had increased their activity to three or more days per week by the time they were surveyed. For some, the benefits extended to measurable medical improvements — one participant reported that their resting heart rate decreased enough for their GP to reduce their beta-blocker dosage.

The social dimension matters too. The study found that encouragement from friends and family, and the feeling of being active in a safe and welcoming environment, were significant factors — particularly for women with heart conditions. parkrun’s community structure provides exactly this kind of sustained, low-pressure social support.

Safety at parkrun

Every parkrun event in the UK is required to have a working AED (automated external defibrillator) present at every event. This is not just a guideline — it is a mandatory requirement. For cardiac arrest survivors, this makes parkrun one of the safest public exercise environments available. You are doing a 5K in a green space surrounded by people, with a defibrillator on site and volunteers trained in its use.

This has made a real difference. David Walker, a 69-year-old survivor, collapsed immediately after finishing his parkrun at Battersea. Volunteers and an off-duty doctor used the parkrun’s AED to save his life. He has since recovered fully and is a vocal advocate for public AED access.

Sean Doyle from Huddersfield had two cardiac arrests before his local parkrun had even officially started. Fellow parkrunners, an off-duty nurse, and a doctor responded immediately. The parkrun community then rallied to buy the event a defibrillator and supported Sean’s family throughout his recovery. Sean went on to complete over 300 parkruns.

These stories are not anomalies. They reflect what the parkrun environment actually is: a community of people, mostly strangers, who look out for each other week after week.

The SCA UK parkrun Group

SCA UK has its own parkrun club. More than 30 survivors and co-survivors have joined, completing parkruns at locations all over the UK and beyond. Every week you can see the consolidated results from all our members — different courses, different paces, all of them showing up.

To join, simply go to your parkrun profile settings and select Sudden Cardiac Arrest UK as your club. Your results will then appear in our consolidated report each week. You can also wear your SCA UK running top to spread awareness — many of our members use parkrun as a way of raising the profile of cardiac arrest survivorship in their local community.

Not Ready to Walk or Run? Volunteer.

Many survivors aren’t ready — physically or psychologically — to participate in the 5K when they first discover parkrun. That is completely fine. parkrun runs entirely on volunteers, and you can get all the benefits of the community, the fresh air, the routine, and the connection without taking a single running step.

Volunteer roles include marshalling the course, scanning barcodes at the finish line, managing tokens, and timekeeping. Most events need six to eight volunteers each week and are always grateful for help. SCA survivor Hugh Burrill, in Australia, began volunteering at his local parkrun while he was still recovering. He found the community and structure invaluable, and only began walking the course when he felt genuinely ready. That is a completely valid and well-trodden path.

Getting Started

Before significantly increasing your activity levels after a cardiac arrest, please speak with your cardiologist or cardiac rehabilitation team. What is appropriate depends on your underlying condition, your current cardiac function, and where you are in your recovery. For most survivors who are progressing well, gentle walking — at parkrun or anywhere else — is encouraged, but the timing varies.

If you get the green light, here is how to get started with parkrun:

1. Register for free at parkrun.com/register — you only ever need to register once
2. Find your nearest event at parkrun.com/events
3. Print or save your barcode — you’ll need it to get a result
4. Turn up at 9am on a Saturday — no need to tell anyone you’re coming for the first time
5. Walk, jog, or run — do whatever feels right on the day
6. Join the SCA UK club in your profile settings so your result appears in our consolidated report

The first one is always the hardest. Many of our members report that they stood at the start line wondering if they were making a mistake — and that within a few weeks it became the highlight of their week.
