parkrun

the5krunner first ran a parkrun at Bushy Park almost twenty years ago, trained alongside several of the original Race 1 runners, and, with a friend, wrote to their MP recommending founder Paul Sinton-Hewitt for the CBE he received in 2014. The technology content, the training plans, and the course guides collected here come from someone who has been inside parkrun from near its beginning, when the fields were small, the barcodes were paper, and almost nobody owned a GPS watch.

Twenty years on, parkrun is one of the most reliable fitness benchmarks available to the amateur runner. It costs nothing, runs every week, and measures the same 5 kilometres on the same course against the same field. No other mass-participation event offers that combination.

That repeatability is what makes parkrun genuinely useful as a performance tool, not merely an enjoyable weekend run. Every other race you enter can be little more than a one-off. parkrun approximates a repeatable experiment unusually well for amateur sport: change your training, choose the right conditions, make a considered decision about which course to run, and the following Saturday gives you comparable data.

The sub-20 question

For the majority of parkrunners who arrive at this site, the question is some version of the same thing: how do I run faster, and how long will it take? The sub-20-minute 5k is the central milestone. Its difficulty varies considerably with age and sex; for most adults without a running background, it requires structured training, though those with high aerobic fitness from cycling, rowing or other endurance sports will often find the barrier lower. It is a good performance by any standard, achievable by more people than believe it, but not without work. The plans and guides here cover every stage of that journey, from a first attempt to break 25 minutes through to the final seconds separating a 20:05 runner from a 19:59 one.

Your barcode and your watch

The practical starting point for any regular parkrunner is getting your personal barcode off paper and onto your wrist. The process is straightforward on both your Garmin Forerunner and Apple Watch; once done, it removes one of the few remaining pieces of friction from race morning. The detailed guide to setting this up, covering the Gasteropod CIQ app for Garmin and the dfyb.run wallet option for Apple is the most-read piece on this site.

Course selection and difficulty

Not all parkruns are equal. The difference between a course built for fast times and one that demands climbing in both directions is substantial and measurable. The difficulty ratings framework developed here quantifies the time penalty for elevation and surface, allowing you to make an informed decision about whether a given course suits a PB attempt or is better treated as a training run. For London specifically, a dedicated guide covers the full range, from Bushy Park, one of the fastest and most storied courses in the country, where parkrun began, to the harder options in the capital. More than forty course guides and videos covering events from Paris to the Cumbrian coast are indexed below.

Age grading

The clock time is only part of the picture. Age grading standardises performance across age groups and sexes: a 65-year-old running 23 minutes and a 28-year-old running 17 minutes can be compared on equal terms. A score above 70 per cent represents a good performance by any standard; above 80 per cent is excellent; above 90 percent puts you among the best age-group runners in the country. The guides here explain how the calculation works and what score is realistic at your current level.

Records and history

parkrun’s 1,000th event at Bushy Park on 31 August 2024 drew 6,204 finishers, a global attendance record. The men’s course record at Bushy stands at 13:48, set by Andrew Baddeley in 2012. The British women’s parkrun record stood at 15:31, set by Melissa Courtney-Bryant at Poole on Christmas Eve 2022, until Innes FitzGerald ran 15:27 at Exmouth on New Year’s Day 2026. These are not footnotes: they illustrate how a Saturday-morning run in a public park became a serious competitive environment while remaining entirely free and volunteer-run.
