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]

The best long weekend of cycling in the UK - PPP222
I can’t recommend this event highly enough. Stunning scenery, challenging and rewarding route, fabulous controls and time to take it all in without worrying about the clock. The set up at Kings works really well and it was a real luxury to have a bed for 2 nights. Thanks to Will and all the volunteers who made this such an exceptional event.
Pauline Porter and the amazing welsh weather
The new 3 day option isn’t easy, but was always the right side of enjoyable, even with the +2000m or so of climb over the BCM. Definitely a great 3 days on the bike, lots of new (to me) roads. Also the bonus of no sleep deprevation and only modest teeth grinding on Gospel pass. Kudos to all the endlessly cheerful volunteers who gave up their time.
As good as it gets
There are two events every Randonneur should ride; PBP and the Bryan Chapman Memorial, this is without doubt the best 600km event I have ridden. A few main roads to make efficient progress in group riding for the first 200km, then the hills start, and every hill rewards the rider with a spectacular view. Most of the energy is returned to the rider on the descents which are glorious, not much wasted in excessive braking. All of Wales in a day, and then back again the next day. Controls are good with not much waiting around for food. The return leg is more testing that it used to be, but avoids sharing the main roads with motorbike clubs on a Sunday afternoon.
Machynleth, Harlech beach, Pen-y-Pass, Menai Bridge, Gospel Pass Tintern Abbey. You will not find a more scenic event, hopefully you will still have enough in the legs to climb the gospel pass after 530km
A challenge has to take you outside your comfort zone.
If this was a flat 600km I would have been happy with getting up and down from Bangor but it wouldn’t have been a challenging ride. The BCM 2024 was a challenge, at least for me, and I’ll be honest, at the time I was incredulous at what we were being asked to climb, but after the fact, and this was perhaps no more than one hour after we finished, possibly as the endorphins kicked in I was elated and knew for certain that I’d never forget this ride – my first BCM. I would seriously suggest that you enter Brevet Cymru (400km) a couple of weeks prior because as well as being a ‘hilly’ warm up it will, if you are a beginner as I was myself, give you experience of riding at night and testing your nutrition strategy. For me Brevet Cymru was invaluable, because it made me change my gearing to one more suitable for hilly terrain, 50/34 up front and 11-34 out back, stock up on gels, and sorted out which lights to use for night riding. It also gave me the confidence to know i could make the sleep control at around 390km. Anyway, for BCM2024 we were blessed with the weather, I just needed arm warmers and a light jacket in the night to keep warm. The route as many will tell you is pretty flattish until Llanidloes when it starts to go up with several steep pitches, especially at Llyn Clewedog and Kings Youth Hostel. If your gearing allows you to turn the cranks within your Z3/4 power output you’ll be fine. Getting to Pen-y-Pass near Snowden is awesome as then is reaching Menai Bridge. Slower riders like myself then left for the final ‘night riding’ leg to Aberdyfi which involves some climbing, but ironically its welcome as it keeps you warm. I slept at Aberdyfi for 2-3 hours, having a drop bag was invaluable as i kept a sleeping bag and gels in it plus the toothbrush. Out in the morning at 6am and i was greeted by the rolling mist receding out to sea revealing a magical seascape dotted with boats, it was genuinely a thrilling moment and the one that i’m happy I had the privilege to see. It’s only just over 200km to the finish, but by God it isn’t easy, and I’ll say it again, I’m glad it wasn’t, I feel a better person for having overcome this challenge. The very best part was meeting other riders. I latched onto someone virtually from the the first climb out of Chepstow and we stayed together for the whole ride, alternatively chatting or just zoning into our task, him climbing ahead, me catching up on the descents, waiting for each other, or stopping when the other needed a rest. Hand on heart `i don’t think I could have finished the ride without ‘Tony’ just being there. The other riders were similarly helpful and full of encouragement.
Finally, the organisation was spot on, not overbearing but offering all you needed to help you on your way.
I coming back. I leant a heck of lot about myself, my equipment, how to paperboy (!!!), and I want to put these to the test, apart from the paperboying, again next year.
Best bike ‘thing’ I’ve ever done.
Wow, what an Audax, my first 600 and what a route to be treated to. Amazing scenery, great climbs, lovely people and smiling faces. The outward leg to the Menai bridge was just beautiful, riding though the dark to Barmouth was exhilarating, a quick nap in a local air bnb and headed off on the return leg.
Eek, what a return leg it was, some absolute beasts to get over, very climby indeed! Such a great was had, thanks to everyone that volunteered their time and helped out, and thank you for the beans on toast and Welsh cakes at the end, it was well needed. Am I up for it next year? Of course I am!!
