Overview
The Pauline Porter Populaire long distance cycling event is a journey the length of Wales from Chepstow to Menai Bridge and back.
Enjoy the delights of the classic Bryan Chapman Memorial 600km but as a 3 day Populaire; a bit hillier, a tad longer, quieter roads where possible, more sleep!

Pauline Porter is the creator of the original Anglesey & Back 600 and a friend of Bryan Chapman; riding the original event with him. I'm proud she has let me honour her by naming this Populaire after her. Pauline will be about during the event so you can have a chat with her about its history.
Resolution 17 to maintain longer Brevet Populaires passed at the AGM.
However it will run as an open event as its integration into the regulations needs to be discussed.
Description
This year the event will be run as an open event. It won't count towards any Audax UK awards or points.
Event speeds:
9.3-10.3kph is the overall speed for the Arrivée opening times.
Daily times are based on 12.5-25kph for each days' latest start. The control opening times for Saturday's & Sunday's first controls are adjusted for any early risers that want to set off from 07:00; this will equate to about 20kph moving average and there will be a few hills before the controls.
Day 1:
07:00 START. Heading north into the Usk Valley you'll make quick progress as the adrenaline rushes you up and over the Black Mountains to Honey Cafe. Follow the Wye Valley, on the old Mid-Wales Railway track bed in places, then utilise parts of the old A470 to Rhayader where you make a beeline to Llandidloes on quieter roads.
The fun begins as you ride up to Llyn Clywedog reservoir on the west side and over the Machynlleth Mountain Road with views of Cadair Idris on the horizon; perhaps one of the best roads in the UK. Cross the Dyfi into Snowdonia and stick to the stunning estuary & coast going through Aberdyfi & Tywyn to get to...
Kings YHA from the top nestled below Cadair Idris' peak for your first sleep stop.
- Distance: 225km
- Climb: 3686m
- Finish by: 01:00 [based on 12.5kph]
Day 2:
07:00-08:00 START: From here you will do the top loop in reverse compared to the other routes so in the afternoon you'll pass the other riders coming in the opposite direction.
Head to Dolgellau and climb up to Llyn Trawsfynydd on quiet roads for a fast descent on the main. Your first control is at Tan-y-Bwlch Station Tea Rooms on the Ffestiniog Railway.
Through Beddgelert you'll pass west of Snowdon to Rhyd Ddu and on to Menai Bridge for the second control.
Coming back climb Pen y Pass from the north before back to Beddgelert. Then along the coast past Harlech Castle and over Barmouth Bridge to Kings YHA for your second night; don't forget to engage the granny gear as you turn off the main road!
- Distance: 173km
- Climb: 2934m
- Finish by: 22:00 [based on 08:00 start @ 12.5kph]
Day 3:
07:00-08:00 START: Heading back up the hill to once again see Cadair Idris' peak you'll make your way towards Cross Foxes. Follow the NCN over to Dyfi Forest and valley before up and over into the Carno. Pass through Newtown then up and over into the quiet Teme Valley to Knighton.
Head south keeping within Wales to Hay on Wye and Gospel Pass, Wales' highest paved road with its stunning views across the Wye Valley!
Descend into Llanthony Valley, opposite the Priory is Treats where you can get some stunning cake.
The final leg awaits to Monmouth and the Wye Valley once more; finishing off by passing Tintern Abbey then back to the Arrivée.
- Distance: 221km
- Climb: 3925m
- Finish by: 01:12 [based on 08:00 start @ 12.5kph]

BCM600 - The Iconic Annual Audax Event with Awesome People and Breath-taking Scenery
This esteemed ride has been on my bucket list since discovering audax. I have to say, so far, it is the best route I have ever done in the UK. Wales.is.fucking.awesome. In addition to the scenery, the people are just as awesome. In 600km only a single honk / shout of us being wankers from a welsh person (a white van). Everyone else was super patient and law-abiding. Always gave us 1.5m of room. Never overtook on a solid line. As we neared England ironically we had 3 motorcyclists (with English accents and union jack plates) honk at a patient welsh driver waiting to safely overtake a rider ahead of us. They then proceeded to box us in and slow down, not letting us pass, with one claiming “you could kill one of us by undertaking”. People are awesome. Well, forget that, the Welsh are awesome. It gives me hope that there is a place not too far away that I would feel very welcome if I ever decided to leave the hustle, bustle, and general self-obsessed in the southeast.
Will is an amazing Organiser and it is my understanding this was his first time taking over as Organiser of the BCM. It went down without a hitch … but for the one unfortunate uncontrollable hitch … which the volunteers were ALL OVER and I could not believe how well they sorted everything out to keep the event moving forward.
Brilliant BCM 23
Superbly run and organised event. Loved the route and the helpers were just brilliant at every checkpoint, with hearty food on offer. Even the weather was well organised. A brilliant way to see Wales end to end in all it’s guises, with some stunning vistas and a decent amount of climbing.
The best of Wales. Twice.
A very fine weekend on two wheels. Helped out by some stunning weather, this was a truly excellent event – a great route, buttery smooth organisation and relentlessly cheery volunteers who couldn’t do enough. Thank you Will and team.
Always one of the best - now it’s even better!
A truly epic weekend’s cycling – epic distance, epic climbing, epic scenery and an epic effort from everyone involved in putting on such a great event. This one felt much more than just another long bike ride – it felt like a proper cycling adventure. Love the changes Will and ACB have introduced – particularly the delightful coastal section on the way home from Kings.
Glorious Wales
A stunning route in beautiful scenery, seeing Wales at its finest. Really well organised by Will and his band of helpers and volunteers who helped shepard weary riders at the stops, helping people find a spot to sleep. Nice to have Fergus the photographer popping up at random spots along the route as well.
It was my firsts audax over 300k and (most of) the climbs were pretty steady affairs. A couple were a bit #willshills, but that was to be expected. Some of the A roads got a bit busy, but that came with travelling that length of Wales and also the weather had all the drivers out.
Nice to spin down the Wye Valley in May as a run in to the finish, although the Llancloudy climb after 575km was a bit unfair!
Looking forward to more of the same.
