Note: list and apps updated as of September 2023, after the 5K app decided to delete the number challenges and parkrun HQ came out with a statement discouraging parkrunners from chasing them. General post refreshed in April 2024.
parkrun does not need gamification and challenges to be great, it can be addictive and enjoyable as a local social event, as an occasional excuse for exercise or as motivation for quick or extended tourism to unexpected locations.
That said, a lot of official and unofficial parkrun challenges have been created to make it more engaging for people who enjoy completing lists and achievements. I find this to be fun, motivational and it helps keeping it new and fresh week after week.
These challenges can take a long time to complete and they are a lot. You can use several apps or a popular Chrome extension to track them.
Order from chaos
Like most ‘fan-driven’ things, the development of parkrun challenges have gotten a bit out of control as it got more successful, so I think trying to create some order around it could be useful

Official vs Unofficial parkrun challenges
1) Official: these are the parkrun challenges that were created by parkrun itself and they are limited to milestones, ie reaching a number of events run/walked or volunteered at.
These milestones are the most well known parkrun challenges and the easiest to track: you will receive an email from parkrun telling you when you have reached one. Also, parkrun sells merchandising to mark your achievements.





2) Unofficial: this is where the real meat is. I will only focus on the parkrun challenges that have become ‘established’. Otherwise, the only limit is your imagination: with the help of the wonderful 5K app, you can create your own challenges and the app will track completion levels for you.
Unofficial parkrun challenges: main categories
1) Indices: just a number. Based on some more or less complicated series of events you have completed, you get a number that gets more difficult to achieve the higher you go. Higher index numbers give you bragging rights if you care about it
2) Completion lists: the bulk of it, complete certain combinations of events or achieve certain combinations of finish times and you will progress on each specific item
3) Maps: originally limited limited to the Chrome extension or dedicated websites, some apps are also starting to integrate them partially. Specifically, the 5K app has included a layer option to see the Voronoi parkrun map in April 2024.
I find the last two groups of ‘achievements’ quite fun and motivational to pick new events to visit while you can see your progress ‘conquering the world’ visually
Indices
Courtesy of the 5K app, the picture on the right shows my ‘indices’ as of 17 May 2023. As an added bonus, it also shows the ‘tourist’ streak, which we can also capture under this heading.

1) Tourist streak: as simple as it sounds, this counts the longest consecutive streak of different parkrun events you have run. Your local event or events you had already visited can be part of a streak as long as you don’t go to the same one twice. A streak is broken when you visit an event that is included in the streak that is running itself.
2) P Index: this one is kind of cool and it gets harder and harder as you increase it. It also incentives mixing tourism with returning to your local favourites, which is a good things. The index shows the maximum number of events that you have run ‘p’ times. In the example, it shows that there are 5 events that I have run at least 5 times. So, to get a p index of 5, you need 25 events, to get it up to 6, you would 36 events and so on.
3) V Index: same as above, but for volunteering. It shows the number of volunteering roles (not venues) that you have performed v times
4) pC-Index: same as the P index, but looking at countries. If you ran 2 events in 2 countries, it will be at 2 and so on;
5) re-Index: how many different locations have you repeated at least once. This index was added by the RunningAchievements app in August 2023

6) Wilson Index: this shows the longest uninterrupted streak of ‘event numbers’ you have run, starting from 1. So, to even start this one you would need to run an inaugural event, which is pretty difficult unless you go chasing them. And you should not do that if you are in the UK.
I definitely do not actively try to increase this one, but it gives an interesting additional stat to look at as it develops naturally.
The screenshot is from the 5K app, which gives also a ‘floating Wilson Index’, looking at the longest streak even if it does not start from 1, to give something to try working on without pushing hordes of tourists to first events.
I picked up a ‘3’ at Wakehurst parkrun in May 2024, but who knows if the actual index will ever start for me. I don’t chase inaugurals, but maybe one day an event will open near me.
My lowest Wilson event is Thames Path, Woolwich, which I was lucky enough to visit on its second ever event – and I loved it.
Maps
These ones are pretty cool, but your mileage might vary if you, like me, have gone pretty much laptop-less outside of work. The main way to enjoy them is via a Chrome extension and until April 2024 there wasn’t any way to make them work easily on iOS. Also, the extension does not offer anything that cannot be found on the more convenient apps. That said, I still go to it once a week because they do show tourist progress in a nice visual way and they also offer new reasons to target your explorations and plan future trips
As of late April 2024, a basic version of the Voronoi map is offered as an optional layer on the 5K app. It does not look as good on a small screen and the algorithm used to calculate the shapes is slightly different, but it is a great addition. As of May 2024, a Voronoi map layer has also been added to the Running Achievements app. I think it looks closer to what we were using to on the Chrome extension, compared to the 5K app option. That said, both are great! You can now start filling your maps also without the Chrome extension if you want to.
A world map divided into geometric shapes (Voronoi diagram) centred around a parkrun venue. The ‘diamonds’ are filled once you have visited an event, giving you a way to track how much of the world, or of your region, you have explored. If you have time and money for it, you could conquer the world, I guess
I have snapped a few screen pictures going from global to local, to give you an idea of how it looks. These represent my progress as of 17 May 2023, when I had completed 101 parkrun across 48 different events and 3 countries (UK, Italy, Netherlands).




Clockwise, the pictures show the global map, with flags showing you where parkrun is present. Need motivation to go to New Zealand for a quick weekend? I’m sure there is someone somewhere who was crazy enough to to do it 🙂
If you zoom in to Europe, you see big coloured diagrams where you have been. The event density in countries other than the UK is much lower, so my Milano Nord or Den Hague events are very visible also from this view.
The UK is parkrunland, so every single event will have a much smaller impact on your progress, especially if you are centred around an area as dense as the South East/London. Before zooming in too much you can see a few escapades from the big smoke: a bit of Surrey, Hove Promenade, Poole… up North you would see South Manchester is also done (day before my first marathon).
But besides those few, I have been focusing on my ‘local’ area. I think this is cool as it shows concrete but slow progress and it forces you to ‘fill those gaps’ motivating you to further exploration. Eventually, my current map-face will swallow Reigate. Sorry not-sorry.
2) Bullseye ‘record chaser’

Same concept, but with a different twist: the site calculates the ‘geographical centre’ of all your parkrun events and calculates a bullseye area of concentric circles around it. Then it gives you a list and a visual map and challenges you to complete it. At the moment I seem to have a demon with the eye set on my current centre (Lloyd). Funnily enough, this became the shape when I ran event 666 in Roundshaw Downs… scary! 🙂
To make things more complicated, the centre of the bullseye target is recalculated every time you run a new event. I have not understood yet if it is a weighted average or a straight one… if the latter, I guess going for a random event in East Asia would put your centre in one of the suspended Russian locations, making things kind of impossible without long haul weekly trips.
Completion lists
And now we tackle the elephant in the room, the many challenges that involve completing words with letters claimed running an event whose name starts with it, running events in specific locations or regions, running specific event numbers or on specific dates or finishing in certain times.
It’s endless and pointless. But fun and motivating.
I will use the two main parkrun mobile apps as the bible to list the most established achievements, but as said, anyone can create a new one and try to push it on one of the many dedicated social media groups.
The tables below show how the ‘achievement tabs’ look in the two main apps, 5K and RunningAchievements. The last picture is the reason why RunningAchievement is still relevant in my view: it offers a ‘regional tick list’ that 5K does not offer.



First off, let’s try to organise them thematically. There is just so much you can do with a run event that wants to de-emphasise times, so it will mostly be achievements based on where or when you attended an event.
- Words and letters: complete a word (real or made up) claiming each letter running an event starting with it or complete the alphabet
- Dates: Run events in certain dates
- Geographic: visit one or more events linked by location or features of their locations
- Events: special occasions or special events
- Number series: claim a number in a specific number series by running the an event number at any parkrun venue

Note that RunningAchievements does not recognise the words for N/S/W/E if they are not spelled in English, while 5K does. Also, RunningAchievements offers a tab to track regional completion achievements similar to Lon-Done and South East for all countries and UK Régions. I have only included Lon-Done and South East simply because those are the two I am currently tracking

Number series
Update as of 7/723: the 5K app has deleted the number challenges on request of parkrun HQ. These challenges do not appear automatically anymore as of this date and parkrun HQ strongly encourages parkrunners NOT TO flock to events on purpose to tick the box on event numbers. This is particularly important for ‘high numbers’ on something like Nelson..
| Achievement | Description | 5K | RunAch | My % |
|---|---|---|---|---|
| Fibonacci | Attend a parkrun whose event number matches the Fibonacci sequence | (X) | 50% | |
| Nelson | Attend a parkrun whose event number is a multiple of 11 | (X) | 78% | |
| Prime | Attend a parkrun whose event number is a prime number | (X) | 22% |
Dear God, it’s like a cult LOL.
I’m looking to do my first Parkrun this Saturday in Braintree. So a streak of one. Winning!
It definitely is a bit of a cult, but a healthy one, so we can let it pass 🙂
Seems fair- looking forward to my induction tomorrow. Do I need to bring something to sacrifice?
Yes, of course, your firstborn. They collect them on Sundays at junior’s
Fantastic he’ll be overjoyed. 😂
Have you thought about adding a colour challenge – parkruns with colours in them – e.g Tyne green or Blackheath
Another one: royalty like Kingston, Queen’s Park, princes, royal tunbridge etc
