All The Welsh parkruns

There are currently 61 parkrun events in Wales of which I have completed 5. The first Welsh event was Cardiff which started on February 16th 2008 and the newest is Llwybr Dyffryn Tywi, Nantgaredig which started on April 11th 2026. The name for having completed all parkrun events in Wales is “Plugged The Leek”.

Severn Bridge parkrun’s start and end are in Monmouthshire, Wales. However the course extends into Gloucestershire, England.

Three 5k parkrun events in Wales have been permanently cancelled: Bodelwyddan Castle, Caldicot and Llanelli Coast. Each has been replaced by other nearby events.

Numbers exclude 2k Junior parkruns and any events that are not open to the general public such as prisons or armed forces facilities.



Welsh parkruns by County

If you’re exploring Welsh geography, the county names can feel a little tangled. Wales has layers of counties: some ancient, some administrative, some ceremonial, and they don’t all line up neatly. Here’s a clear guide to how the historic and preserved counties fit together.

The historic counties, with names like Glamorgan, Pembrokeshire, and Denbighshire, date back to the 16th century, when the Laws in Wales Acts (1535–1542) established them as the framework for local government, justice, and taxation.

They no longer have any official administrative role, but they remain deeply woven into Welsh life. People still use them for cultural identity, local geography, sporting organisations, and heritage. In many ways, these counties are the mental map that Wales still lives by.

The preserved counties are much more recent. They are based on the administrative counties created in 1974, when Wales underwent a major reorganisation of local government. Those 1974 counties, such as Dyfed, Gwent, and Clwyd, ran local services until 1996.

In 1996, another restructuring replaced them with today’s 22 principal areas. At the same time, the preserved counties were formally created to keep the old 1974 boundaries alive for ceremonial purposes.

Today, their role is narrow but important: they define the areas served by the Lord-Lieutenants and High Sheriffs of Wales. Beyond that, they don’t influence local government or everyday administration.

  • Glamorgan is the Welsh historic county with the most events at 19. Montgomeryshire has the least with 1 event.

  • Gwent is the Welsh preserved county with the most parkrun events at 12. Powys has the least with 4 events.

  • Cardiff and Gwynedd are the principal areas with the most parkrun events at 5 each. Merthyr Tydfil and Wrexham have the least with 1 each


All of the Welsh parkrun events …

Below are each of the Welsh parkrun events in alphabetical order. A few things to note:

  • The interactive maps below take you to the approximate location for the course, typically the centre of the park. See the course instructions in the parkrun page for each event for specific directions to the start.

  • Course maps and elevation profiles show the route at the time that I ran it and may have changed since then. See the Course page in the event’s page on parkrun.org.uk for the current course outline. Note that course outlines are from Garmin data during a specific run and may vary from the officially measured distance.

  • Please contact me If you spot an event that doesn’t have a course map and elevation profile and you would like to donate one from your own run. I’m also interested in maps and elevation profiles for courses that have changed or where there’s regular alternative route (e.g. Horsham). I’ll need a GPX file from your run plus the date. I’ll include a credit for you and will donate £1 to parkrun.

parkruns are free, weekly, community 5k events all around the world. I started in December 2012 and have been obsessive about it ever since. See my parkrun Collection page for details.

Western Wales County Tops

View from Aran Fawddwy


“Remote” and “obscure” are relative terms. If you live in Aberystwyth then Arran Fawddwy, Plynlimon and Foel Cwmcerwyn are all local and accessible peaks. If, like the rest of the us, you don’t then they’re a bugger to get to.

Over my 7 years of County Topping I’d managed to pick off the rest of Wales. Snowdon came first and I’d repeated it several times. The rest of the North was ticked in one trip in 2016, the South in 2014 and all between came on weekend adventures over the years. The final 3 are pretty well spaced out so they could only be done on a road trip rather than a single location adventure. If I’d known earlier that this trip would be such fun I’d have tackled these much earlier.

As is mandatory for all weekend trips now, travel happens on a Friday after work. Saturday starts with the nearest parkrun not yet done. This time is was Dolgellau, a beautiful course along the Afon Mawddach river and Madwddach Trail. The National Cycle Network signs along the route reminded me that I’d passed through here before on my NCN8 end to end Wales trip in 2010.


Arran Fawddwy

Significance: Highest peak in Merionethshire (Historic CT)
Member of: Hewitt, Marilyn, Nuttall
Parent Peak: Snowdon. NHN = Peak 931
Elevation: 907m
Date climbed: June 22nd 2019
Coordinates: 52.7880° N, 3.6881° W

Llanuwchllyn, our start point for the Arran Fawddwy, walk was only 20 minutes from Dolgellau so we were on the trail by 11:00. We were lucky with the weather and had a the most amazing sunny day with clear skies and view for miles. The 360° view from the summit was a rare prize amongst so many cloudy summit days in my Welsh trekking experience.

Arran Fawddwy is a long but easy trek with only a small bit of scrambling in the last 20 minutes. It’s quiet up there too. At 2976 feet it narrowly misses out on being in the Welsh 3000s and the nearby Cadair Idris gets much more attention. If it wasn’t for it being a County Top I’d likely never have gone there either. That would have been a shame as this was one of my most enjoyable UK hikes in several years.

Once off the mountain we drove an hour South to the YHA at Borth. I didn’t know what to expect when I booked this one. My friend who was in charge of accommodation booking had made such an arse of it, I had to take over with only a month to go. This one was booked on the only criteria that it was near Plynlimon and still available.

As it turned out, Borth was a hidden gem. It’s an old Seaside resort that missed the memo about the need to become cheap and tacky. Our room in the YHA was spacious and had a sea view. Dinner in the seafront Victoria Inn and a beach walk back topped off a perfect adventure day in Wales.


Plynlimon

Also known as: Pumlumon Fawr
Significance: Highest peak in Cardiganshire (Historic CT), High Point of the Preserved County of Dyfed and the Principal area of Ceredigion
Member of: Hewitt, Marilyn, Nuttall
Parent Peak: Pen Y Fan. NHN = Craig Cwm Amarch
Elevation: 752m
Date climbed: June 23rd 2019
Coordinates: 52.4675°N 3.7828°W
Route Start / End: Out and back from parking place on Nant-y-Moch eastern road plus a loop of Pumlumon Fach
Route Distance: 7.7 km (4.8 miles)
Route Elevation Change: +/- 400m
Subsidiary tops on route: Pumlumon Fach (664m)

Plynlimon is just a few miles as the crow flies from Borth. We were driving though so it took a winding 45 minute trip so many hairpin bends and a route around the Nant-y-Moch reservoir.

The start of the trail is a small parking spot on the Maesnant road where it meets a farm track. There's 2 options from here: an out and back following the Maesnant stream or a circuit of the Pumlumon Fach. As we were following Jonny Muir's guide an wanted a more interesting route. We opted for the circular plus a couple of detours to bag the summits of Pumlumon Fach and an unnamed peak nearby.

Plynlimon was a much shorter trek than yesterday's Arran Fawddwy trip so we were back down by lunchtime and quickly on the road towards Newport YHA. Even with a short stop to bag a bonus Trig Pillar near Cardigan we arrived at the YHA by 15:00. I'd not read the check-in instructions so didn't realise that we were 2 hours too early. We could get a whole other mountain bagged in that time.

By the time wed reached the parking spot for Foel Cwmcerwyn it was proper rainy. The summit was apparently not far away but we couldn't see anything. Sticking to the GPS route and a straightforward path we arrived at the Trig Point in under and hour. The completion of the Welsh County Tops was a bit of an anticlimax in a damp field with views stretching across the nearest 15 metres.




Lôn Las Cymru: Cycling The NCN Route 8 Wales End To End

Cycling the NCN route 8, the Welsh End to End, was my alternative Stag Do. Although I had a more traditional one, my interests at the time were returning to the outdoors and this would end up being more memorable. It was a four day, three person adventure through the the heart of Wales.

The route is also know by its Welsh name, Lôn Las Cymru, which means Wales' Blue Lane. I'd only heard of this name in the last few years so I assume it adopted it since our trip. Whatever the name, it's a great North-South end to end as an alternative to, or warm up for the much longer LEJOG.

Unlike LEJOG the far ends of the route are easily accessible by train. We were travelling up from South East England and took a train from London Euston to Crewe then the North Wales Coast line to Holyhead. The return trip from Cardiff is even more straightforward with many options for trains heading east into England.

Once a busy port town for ferries to Dublin, Holyhead has lost its way in recent years. There's not much reason to stop in town now if you're taking the ferry. We were just staying one night but quickly ran out of things to do. It was a few years before I'd started my UK County Top obsession. If I'd known at the time it would have been a short cycle to Holyhead Mountain to bag the highest point in Anglesea. I returned a few years later to claim it on a tour of the North Wales County Tops.

After a good night's sleep we set off early to find the start of the route and make our way south. Splitting the trip into 4 days gives you enough time to see the country and get enough miles in. It also nice splits into 4 distinctly themed days.

Day 1 is beautiful, cutting through the heart of Anglesea, over the Menai Bridge and across the top of the Llyn Peninular. By contrast, Day 2 is hilly with more dramatic scenery as you curve round the south western edge of the Snowdonia National Park. Day 3 is a gentler descent through mid-Wales through some stunning countryside often overlooked by tourists. Day 5 is the Grand Finale, tracking the Taff Trail through the Breacon Beacons National Park, through the valleys to Cardiff Bay.

For a more detailed description of the route I recommend the section in Big Rides (look out for my own Day 3 photo on page 76).
