The Classic End 2 End. Legend has it Bryan Chapman would cycle the length of Wales and back to go see his mechanic; come follow in his pedal strokes!

The classic Bryan Chapman Memorial is the 600km randonnée to do!

New for 2024 are two variations giving more sleep over similar routes. The Anglesey & Back 300+300 and the 3 day Pauline Porter Populaire 2-2-2.

Start times:

Published start time is 06:00.

Additional start times will be used up to 04:00 so please factor this into your planning for travel/accommodation.

Your start time/group will be based on your selected average moving speed and be provided 2 weeks before the event.


This long distance cycling event is a journey the length of Wales from Chepstow to Menai Bridge and back.

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 for the first control. Then follow the Wye Valley, on the old Mid-Wales Railway track bed in places, to Llandidloes.

Shortly the fun begins as you ride up to Llyn Clywedog reservoir 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 then another climb into Snowdonia with more mountain views and perhaps a low flying RAF plane as you join the Mach Loop round to Dolgellau.

A third done and you are at Kings YHA, the third control; don’t forget to engage the granny gear as you turn off the main road!

From here you head across Barmouth Bridge on the shared path then up the coast to Harlech Castle and on to Beddgelert. Climb Pen y Pass nestled under Snowdon‘s peak before descending to Menai Bridge Heritage Centre for the fourth control; this is the old church hall used by the original event back in the 80s.

Half way, hopefully no visit to a mechanic like Bryan Chapman would, now back you go; this time to the west of Snowdon through Rhyd-ddu. This year you will retrace the route back to Barmouth and around the coast to Aberdyfi for the sleep control; easier and flatter into the night along the coast.

From here it is off to Newtown with a gradual climb from the Dyfi & Twymyn valleys into the Carno. Then up and over into the quiet Teme Valley passing through Knighton.

Again the route changes for this year heading south keeping in Wales as much as possible; the flatter night section earlier allows the inclusion of Gospel Pass, Wales’ highest paved road with its stunning views across the Wye Valley and little overall effect on total climb.

Descend into Llanthony Valley; opposite the Priory is Treats the final control where you can get some stunning grub.

The final leg awaits to Monmouth and the Wye Valley once more; finishing off by passing Tintern Abbey then back to the Arrivée.

  • Food & drink provided at start, Kings YHA, Menai Bridge, Aberdyfi & the Arrivée.
    • The ‘menu’ will be provided later with the final ride details.
    • Every endeavour will be made to cater for all dietary requirements.
    • However if you require specialist provision any precooked meals you provide can be transported from the start to the controls.
  • Bag drop provided to Aberdyfi.
  • Airbeds and blankets provided at Aberdyfi.
  • No showers currently – working on getting the local football club’s up and running for the event.

Camping Friday night: £7 tent | £10 van
Parking Saturday & Sunday: £5

The best BCM yet

23rd May 2023

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.

The best long weekend of cycling in the UK - PPP222

30th May 2024

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

29th May 2024

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

29th May 2024

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.

29th May 2024

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.

This is what 'audax' is all about. Travelling between controls to collect proof of passage (PoP) to prove you have cycled the distance. The above controls are found in your brevet card, the route notes, as POIs with the route, and waypoints with the GPX. Your brevet card it to be filled out as you progress around the route. PoP is obtained in several ways. It is highly recommended you carry a pen or pencil to fill your brevet card as you go; if it is a long event numbering any receipts to correspond with the control number will save you time later, then keeping them in order is next level!

Types of control:
  • CONTROL - a place or venue where you obtain PoP which can be done in several ways. You will be able to get food and/or drink, also WC will be available.
    • Manned - a volunteer or venue member of staff will stamp your card providing PoP. All controls are thus unless specified as...
    • Free - you must obtain PoP from that place that has a time and date, usually a receipt from a cafe, shop or ATM.
  • INFO - a question found in your brevet card that is relevent to the location needs to be answered and recorded.
  • CHECKPOINT - similar to a control but there may not be any facilities present.
  • SECRET - now that would be telling wouldn't it!

I use the RWGPS app on my phone to navigate audax events by using spoken cues, I also use it to route check and proof my route notes. This IMHO is the best of all worlds. I don't need to look at a screen (but I can check if I want), I get clear directions when needed (you may need to get used to my shorthand which gets spoken as such), I get a warning if I'm off route, the battery lasts a lot longer than constantly using the screen; especially nowadays as phone batteries are getting bigger plus many are able to rapid charge in a short amount of time. All you need is a good case and mount for inclement weather.

  • Install the app.
  • Join the event.
  • Go to the route.
  • Send to device.
  • Open app and confirm download.
  • In settings (exact location varies depending on iOS or Android) to optomise for best battery use:
    • Logging - adjust interval: every 10s is best for the battery, logs your ride but won't get you any KOMs; every 1s uses 10x more battery power to write data but may get you a KOM if you pedal quick.
    • Navigation - Spoken alerts ON | Off-course alerts ON | others at your discretion.
    • Handlebar mode ENABLED - this will keep RWGPS above any screen lock so you can recall it if needed by pressing power button or similar.
    • Handlebar mode - Screen OFF for cues | Proximity Wake OFF (otherwise changes in light will turn the screen on) | Keep screen on NEVER.
    • Offline mode ENABLED - when you start riding.
  • Better still use flight/aeroplane mode whilst riding.
  • You can adjust the text-speech settings via your phone settings; the type of voice, playback speed etc.

Most of the battery drain on a phone is from the screen. By using voice commands you eliminate this but can still view the map if needs be. The second biggest drain whilst cycling is the phone itself searching for a signal as you move between cell towers; putting the phone into flight/aeroplane mode whilst moving solves this problem; you can easily turn data back on to #tag that #CAKE at the next stop!


Make sure battery optimisation is turned off otherwise Android will recognise RWGPS as an excessive battery drain and can limit its functionality. This will be particularily evident if you stop for a bit without GPS signal then continue; the app will appear to be functioning correctly but Android will limit it and data can be lost from the stop point until the app is restarted. There may be a similar feature in iOS.

  • Settings >Apps.
  • Find RWGPS and expand Advanced >Battery.
  • If it says optomised then select and wait for all apps to load.
  • Make sure the apps displayed are 'All apps', find RWGPS and select.
  • Select 'Don't optimise'. Exit settings.

You have agreed to and declared that at the time of the ride...

  • You have no symptoms relating to COVID-19.
  • That you are not self-isolating.
  • That you are not required to quarantine during the period of the event.
  • That no local or other regulations prohibit you from attending this event.
  • You agree that if you develop any such symptoms before the event you will not attend.
  • You agree that if I develop any such symptoms immediately after the event I shall inform the organiser.

Please follow any wishes of private establishments en route. I highly recommend carrying a mask/buff/scarf etc for the simple act of covering your face if needed when indoors. Any specifics requested by controls will be noted in the control tab.
