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]
Reviews
What others think.
BCM 23
This was my second BCM , and loved the changes made in the second half from Newtown to the shell Garage .
Would welcome changes to the first half ( If Possible) to used some quieter roads .
Organisation first rate from Will and the team from ACB . The Food stops worked very well with the staggered start .
Maybe would like to see an Outdoor food stop control with about 50/60:k from finish.
As it was ACB first BCM event I’m pretty sure that this well run Event will be even better in the future.
A fun weekend
Superb. Enjoyed the route even more than my 12 previous BCM’s
Great TLC from ACB pals, plenty of food, nice bed at Kings
Liked the day two route via the coast instead of Cross Foxes
Not getting any younger so it wasn’t that quick but would do that weekend again!!
The best BCM yet
Superb. Enjoyed the route even more than my 2 previous BCM’s, particularly the ‘morning’ (for me) section around the headland to Aberdovey. Although the night section shortcut through Rhyd was one kicker of a climb I’d happily avoid next time. The run back through the lanes around Weobley was far more enjoyable than previous routes down through Llandrindod Wells, even if it was a little slower going. All the organisers and helpers were fabulous and the ACB riders in particular were very friendly. The weather wasn’t bad either 😉 thanks Will.
Amazing view
This was really one of the best ride regarding the scenery. Less hilly and it would be probably the best one. The organisation and controls were great too. I loved it but my legs and bum didn’t. Would I do it again, yes if I have more comfy saddle.
Stunning
I’ve done a lot of cycling but this (2023) was my first Bryan Chapman. Bottom line: absolutely stunning, the best cycling event I’ve done in years. Incredible challenge, mindblowing scenery, fantastic organisation. Top marks to Will and his team. Thanks.
